Is Studying a PhD in Computer Science a Crazy Idea? Pros and Cons

Are you considering a PhD (Doctor of Philosophy) in Computer Science but feel pretty unsure whether it's the right thing to do?

Gather round cos I've recently been weighing up this decision myself!

I don't mind getting stuck into books and studying, I also love the University experience.

So, it's got to be a rewarding experience! And should help further my career.

The answer turned out a bit more nuanced than that!

I know that as I've spent hours trawling the web for opinions, experiences and advice on sites like Quora and Reddit. This article is a summary of that work, listing every pro and con I could find.

1. What are the Pros of studying a PhD?

There are a few career paths facilitated by studying a PhD

• Academic research
• Commercial research (think having a role Google's DeepMind)
• Teaching at the college/university level. [3]

I haven't listed software development as a PhD is definitely not required to become a coder.

A bachelor's degree in Computer Science or Software Engineering is the requirement for most companies. Either of those degrees will give you the foundation necessary to understand programming at a deeper level and prepare you for a career in industry.

A PhD is mainly about research and opens up a host of advance and research-oriented opportunities. [2] The primary requirement to earn a PhD is that you must create new knowledge about your subject. . [5] [4] Even as a Professor, research may still feature high in your tasks.

There are, however, an increasing number of PhD jobs required in computer science such as research scientist for many of the top tech companies, where you would cover many of the same duties as during your PhD but on their commercial behalf. [3]

Even if you pursue a role as a coder, having a research focused background as a developer can help set you apart and bring new strengths and perspectives to a development team.

A PhD encourages you to take a more holistic approach to project solving. [3]

I like this quote I found from a developer:

"_Having said that and having been working in (effectively) an industry developer job for the past five years, what I've found is that my training has prepared me very well to ask questions at a higher level of abstraction, to recognize and plug gaps in our knowledge, and to think a bit beyond the highly focused build this now mentality that often drives development. _" [3]

During a PhD, you master teaching yourself how to learn, how to write well, and how to methodically solve problems. [3]

Additionally, many come into a Computer Science PhD from different fields and actually learn to code on the course. Switching to Computer Science at PhD level, where you solve problems with practical skills and technology, may ultimately benefit your career as compared to staying on your current trajectory.

1.3 It's Interesting

You've got free access to the latest/classified research, top class library services and access to leading professors in their field.

1.4 Prestige

Pulling off some high level and published research may bring you notoriety, eventually allowing to become recognized as a famous Professors/Researcher such as Canadian computer scientist Yoshua Bengio. [6]

1.5 Networking

You will undoubtedly meet some inspirational and well-connected people from all over the world.

Often those pursuing a PhD are among the most intelligent and educated of society. The crème de la crème of their perspective countries. Networking with them, and building friendships, will open a host of new career and travel opportunities.

1.6 It's Fun

Universities are a highly concentrated spaces of dynamic and energetic people.

You've got societies to pursue your hobbies and interests, parties and the good old university bar. Not to mention, subsidized gyms, food and often, accomodation.

Some of us, myself included, thrive in such as environment.

1.7 Self-fulfilment

A PhD will help feed an intellectual curiosity.

Do you like to inquire, invent, create, explore, read, discuss, ponder, teach and discover the unknown?

Compared with the rigid tasks of a normal job, a PhD let's you pioneer research, sketch out solutions to the unknown and share all of that with the world through academic publishing.

If you're the type of person who doesn't want to merely make things but understand why things work, a PhD might be for you.

2. What are the Cons that come with studying a PhD?

2.1 narrows your focus.

During a PhD you study a subset of Computer Science and although you become an expert in that area, you may lose touch with the broader understanding of the field.

For example, being super knowledgeable about, say, Convolutional Neural Networks (CNN) while knowing little to nothing about Recurrent Neural Networks (RNNs) or even more basic ML models (e.g. Logistic Regression) will reduce your overall employability to a very specific number of jobs. [1]

Unless you attain a scholarship, there is a hidden cost to PhDs that's notwithstanding the fees.

Those with a bachelor's or master's degree pursuing an industry role will be able to earn well, save and invest for the future.

PhDs are, therefore, incredibly expensive because your stipend is low compared to industry salaries and you are losing out of several years of salary reasonably early in your working life.

If you take into account compound interest, these few years will be worth the most when you retire. If you get average 8% return on investment, every $100k now earnt is $1M when you are 60. [7]

You can probably get a higher salary after getting a PhD, but chances are, if you continued working for 4-5 years, you would be getting similar salary as well.

You need to consider whether the non-monetary rewards of a PhD are worth that hidden cost.

The 5 or more years of your life exchanged for a PhD are, for most people, among your most productive, fruitful, healthy, and responsibility-free years of life.

Some people prefer to use that time climbing the career ladder, renovating a home, spending time with relatives or starting a business.

Attaining a PhD is a grind where constant and long-term deadlines are a stress that hangs over you.

2.4 Supervisor

During your PhD, you will generally be monitored by a supervisor.

Something I've seen come up a lot is that many students experience a bad relationship with their supervisor or feel that they're being steered in a direction contrary to their interests.

Studying a PhD doesn't equate to free reign. Be prepared to compromise and answer to a someone else, much in the same way in the real world.

2.5 Isn't Needed For Majority of Industry Roles

As rightly discussed in the pros, certain research career opportunities arise when studying a PhD.

However, for the majority of software roles, everything you can do with a PhD you can also do with a BSc or MSc. You might even be considered over-qualified for some jobs.

PhD students are also more likely perform worse on technical interviews than non-PhDs as they're often out of practice with coding (being so focused on research). Or, if they do code, it's in a more obscure language. [7]

With or without a PhD, you have to answer the same questions when interviewing in the industry: what can you do, what have you done, what skills and qualities make you the best candidate and the best fit?

Top tech companies judge you based on your interview performance, not your resume.

You may aspire to a faculty role, working as a professor, however, industry roles are often more numerous, more generously compensated, and provide a better work-life balance.

Research roles may also require you to move yourself and your family to wherever tenure beckons.

This point is contested but in some specialties of Computer Science, the research in industrial settings is arguably more relevant and more interesting, think of the research that Google and Facebook conduct in their own R&D departments.

2.6 A PhD is Antiquated

The concept of a PhD precedes the online education revolution of recent times, driven by technology and the limitless amount of information and tools available to us.

Nowadays, you can get PhD equivalent knowledge and skills in many fields just by learning on your own without costly time, energy, and career sacrifices using online courses (Code Academy, Coursera, edX, MIT OpenCourseWare , Udemy, etc.) [1]

Additionally, you are not limited in any way to keep up with trends, connect with leaders in the field, go to conferences, and immerse yourself in the field. Many industry practitioners indeed do.

2.7 It's hard

Doing a PhD will be completely different to your day job.

You probably find the technical side of your job pretty easy most of the time but your PhD should genuinely challenge you (if it doesn't, you've chosen too easy a project).

But there is also the psychological aspect of a 5+ year project that will sometimes feel like it's going nowhere. Although your supervisor will guide you, they won't give you the answers on a plate. It can be lonely. [1]

If you do not have the skills to learn on your own, nor motivation, curiosity, and discipline to manage your learning process, you're going to find it incredibly difficult and without a guarantee you'll actually graduate.

3. How to decide whether to pursue a PhD?

With all this taken into account, how do you come to a conclusion?

The most important question to start with is: "Can you do what you want to do without a PhD?"

Note, that you can't skip this question by saying, "Well, I don't know what I want to do." In that case, you need to figure it out before returning to the PhD question.

Also consider that for any given goal, getting a PhD will almost always be the "hardest way" to accomplish it. But for a select few number of goals, getting a PhD is also the only way to accomplish it, and therefore by definition also the easiest way.

For example, see yourself a 'professor and best-selling in a top academic institution' - then a PhD and the experience of one could be for you.

There are also two additional considerations _

Do you have a family to take care of, and can you do so just as well while working on a PhD? If you are currently raising a family, paying a mortgage on a home, and trying to send your kids to the best schools, then I would think long and hard before starting a PhD. A PhD is likely to substantially decrease both your time and money, two resources you need a lot of when you have a family.

If you don't currently have a family, mortgage, car, etc. doing a PhD may push certain life goals quite a bit further down the road.

Where are you planning to get your PhD from, and who will be your advisor? The institution you choose to do your PhD matters a lot more than where you did your undergrad. You really need to find a department that has the right reputation for your research interests.

My advice is, in order of priority:

• Do what you enjoy and will make you happy
• Do what will help you achieve your long-term goals
• Recognize that "success" means different things to different people
• Do not follow a path to satisfy someone else's aspirations
• Ensure it's the right time and that you can afford it

Basically, it's this - Pursue a PhD because you really, really want to explore and push the boundaries and you think it that will directly benefit your long term aims.

But, walk into it with the realization that it is very hard to get a job in academia (there are many more PhD grads than there are openings) and you may wind up back in the industry - the same place you would have been before, but years earlier.

Remember! You do not NEED a PhD. So it's OK to apply, see who admits you, and then decide if you really want to go or not. You should not decide to do a PhD, apply and then simply go to the best place that accepts you without proper consideration of all the points in this article. That's a recipe for misery! [1]

What is a phd in computer science.

A PhD in Computer Science is the highest level doctorate degree you can earn. Once you finish your undergraduate degree in Computer Science or a related field like Engineering or Applied Mathematics, you can apply for your doctorate degree .

If you didn’t major in Computer Science, then earning your Master’s degree in the subject will help you on your journey for your doctorate degree. Although it is not required to apply for a PhD, having your Master’s degree first is generally preferable.

Most programs require the following, along with a degree, to apply for a PhD:

• Previous research experience
• Letters of recommendation
• A high GPA (about 3.5-4.0)

Program Length

Earning your PhD in Computer Science is not for the faint of heart as it requires a lot of time, energy and perseverance. Although the length of completion depends on your enrollment status of full or part-time, it typically takes 5-6 years to finish.

Opportunities and Challenges

As the top academic achievement within the field, a PhD exposes students to high-level information, as well as some of the hardest challenges facing the world and technology. A PhD grants students the opportunity to perform the research of their choice and explore the topic that interest them the most.

Upon graduation, a PhD student can continue with academia or enter the industry. However, if you want to enter the field as a Computer Programmer, Software Developer or the like, you don’t have to earn a degree at this level as a Bachelor’s degree will suffice. In fact, some jobs may consider a PhD candidate to be too highly qualified, so you’ll want to assess your future goals before enrolling in a PhD program.

One of the benefits of earning this doctorate degree is the freedom you have. Most programs are quite unstructured, meaning that you get to choose what you want to research. Therefore, you can be a leading expert in the field and help to shape policies around artificial intelligence, automation and technologies that are changing the way the world functions.

The deep and rich education can expand your horizons and help you understand ideas and topics that you would never have otherwise considered.

Potential Jobs

Although it is possible to enter the field of Computer Science without a PhD, having the knowledge will expand possibilities and increase your pay.

Some of the job titles that PhD candidates seek include:

Computer and Information Research Scientist:

People in this position help to invent new programming languages that enhance business practices. With the high amount of data, information and research, these scientists can create changes and also assess their impact through analysis.

Database Administrator:

Database administrators organize and secure data against attacks. Those with a PhD can be trusted to understand the complex nature of various systems and be able to better protect them.

Software Developer:

Software developers create systems and software for various uses. Although a PhD is not required to be a software developer, it further enhances one’s understanding.

Computer Science salaries vary based on position type, location and education. However, the overall field of Computer Science is growing. In fact, Computer and Information Research Scientists are expecting much higher than average growth with the discipline expected to increase its demand by 19% between 2016 and 2026. Those with a PhD will increase their salary potential based on their educational accomplishment.

Furthermore, with a PhD in Computer Science, you can go on to be a professor since you’re a leading expert in the field. The demand for jobs within the field is growing, especially regarding cloud computing, data storage, artificial intelligence and information security.

Online Versus Traditional Programs

The reason you choose to earn your PhD in Computer Science is personal, and how you choose to do it is also a subjective choice. It’s hard to say if an online university or traditional onsite program is better or worse because the reasons for choosing to do one or the other are different.

The benefits of an online program include relatively lower costs, more flexibility and greater accessibility. However, an onsite program offers you more opportunity to perform research and work with those in person who are already advancing the field.

For example, some students who earn their Bachelor’s degree in Computer Science online from University of the People may enjoy the online experience and therefore want to continue their studies remotely by earning their PhD online as well.

Earning your undergraduate degree is the first step in moving towards earning your PhD in Computer Science. While the field is always growing and the opportunity for research multiplies, pursuing a PhD in the discipline is an important decision to make. The program generally offers freedom to select your area of interest, but it also takes time and a lot of dedication to complete.

Those who go on to get their PhD should really have an affinity for the subject matter and love to conduct research. It’s also useful to know that it’s typically easier to earn a PhD then enter the field as opposed to working in the field and then going back to earn your PhD.

Any form of higher education will never serve as a detriment as it helps expand your mind, create more networking opportunities and better hone your skills and knowledge regarding specific subject matter.

Online PhD Computer Science Degree Courses

The first few years of your doctoral program will probably be dedicated largely to coursework. Class offerings can vary greatly among schools, and you’ll usually have a good deal of latitude to select topics that correlate to your area of interest.

There may be a few foundational classes that all computer science doctoral students are required to take. In addition, you may need to ensure that your course schedule includes at least one class from each required category; for example, you may need a theory class, a programming class and an applications class.

• Artificial Intelligence – your time in this class can help bring you up to speed on some of the latest advancements in artificial intelligence and give you an idea of the direction that this technology may be heading. You’ll likely discuss search algorithms and probabilistic models.
• Databases – this course explores advanced topics in creating and using databases. Data analytics will likely be an important component of your studies, and you’ll probably discuss query optimization and warehouse modeling.
• Graduate Algorithms – this course can help equip you with skills and tools for advanced data collection and analysis. The topics may include hash tables, linear programming, max-flow algorithms, and dynamic programming.
• Programming Languages – your earlier academic programs probably introduced you to the basics of using programming languages, and this doctoral course is designed to build on your object-oriented and functional programming skills. You’ll likely talk about applying algorithms and running optimizations.
• Project Management for Software Design – creating a new program or operating system can involve coordinating numerous people over a long span of time. This class covers how to provide organized leadership for the process and ensure that all involved parties stay on the same page.
• Research Methods – by teaching you how to conduct original research, this class can help you get ready for your dissertation process and your future career ambitions. You’ll likely discuss different research methods, be asked to consider how bias can affect results, and be expected to demonstrate your research skills.
• Teaching Methodologies – after completing your doctoral work, you may aspire to become a university faculty member. A teaching course can help you develop your instructional skills and may give you opportunities to lead classes.

Although you can probably select many of your own classes, there will be a set number of credits that you must earn. After completing your required coursework, you will probably need to take a qualifying exam. Passing this test is usually a prerequisite to beginning your dissertation process.

Careers in Computer Science for PhD Graduates

Your doctoral degree in computer science can help prepare you for jobs in tech companies, the business world, academia, or research.

Your advanced education may qualify you for leadership roles in which you direct teams of employees or spearhead tech innovations. The field of computer and information technology is growing, and the Bureau of Labor Statistics predicts that 531,200 new positions will be added for the next ten years.

The federal government is one of the largest employers of computer and information research scientists . Other potential employers include academic institutions and research organizations.

Software and computer companies also hire computer researchers. These professionals often work in urban centers, and the East Coast and the West Coast have some of the highest concentrations of computer scientists.

As you advance, this job has the potential to become quite lucrative; the top 10% of researchers in this field make over $189,780 each year.

Computer Science Professional Organizations

As a leader in computer science, you should continually strive to improve your professional abilities and to advance the field. Joining industry organizations can help you achieve those goals.

• Association for Computing Machinery – ACM is a worldwide organization that promotes networking, research, industry advocacy, and ethical conduct among members. The group maintains the ACM Digital Library.
• CompTIA Association of Information Technology Professionals  – CompTIA offers certification programs, and those who qualify are automatically enrolled for membership in this support and advocacy group. Non-certified professionals and students are welcome to purchase a membership as well.
• Computing Research Association  – Computer researchers from government, business and academic institutions collaborate through CRA.
• IEEE Computer Society  – IEEE’s global network includes people who work in the engineering and technology fields. Societies allow members to join specialized subgroups.

Joining these organizations can provide opportunities to learn from others and to share your knowledge.

Accreditation for Online PhD Computer Science Programs

Any school that you choose for your PhD program should be accredited. As with your bachelor’s and online masters in computer science programs, the best type of accreditation to consider is regional accreditation. Employers are unlikely to hold a degree from an unaccredited school in high regard.

Regional accreditation is granted by organizations that are approved by the Council for Higher Education Accreditation and the U.S. Department of Education.

These groups include:

• Higher Learning Commission (HLC)
• Middle States Commission on Higher Education (MSCHE)
• New England Commission of Higher Education (NECHE)
• Northwest Commission on Colleges and Universities (NWCCU)
• Southern Association of Colleges and Schools Commission on Colleges (SACSCOC)
• WASC Senior College and University Commission (WSCUC)

The most important reason to choose a regionally accredited school is to ensure that your degree, whether earned online or on campus, is respectable. In addition, accredited programs are eligible for federal financial aid, and credits may be transferrable elsewhere.

Financial Aid for PhD Computer Science Students

Doctoral students often have access to multiple funding options. Some schools allow students to serve as research or teaching assistants, and they receive a stipend in return. You can ask your school’s financial aid department whether you will be eligible for an opportunity like this or other doctoral funding.

In addition, you can fill out the Free Application for Federal Student Aid (FAFSA) to find out what federal or state assistance, such as grants or loans, you can receive. You may also be able to get doctoral fellowships through your school’s computer science department or a private organization.

Is There a PhD in Computer Science?

Yes, computer science is a common PhD offering at many universities. Computer science doctoral candidates may perform research related to artificial intelligence, databases, information technology, programming languages, or algorithmic theory.

You may take courses like Deep Learning, Graduate Algorithms, and Semantic Information Processing. Earning this degree may allow you to advance fields like technology, medicine, education, or journalism through innovative computer developments.

Can You Get a PhD in Software Engineering?

Yes, a PhD in software engineering is an option at many schools. In such a program, you may explore human-computer interactions, data collection from software, and methods of software testing. Your studies may prepare you to work in software research and development or to teach software engineering at the undergraduate or graduate level.

How Long Does It Take to Get an Online PhD Computer Science Degree?

Students’ time in doctoral programs can vary, but you may be in school for three to eight years in either an on-campus or an online PhD in Computer Science program.

• Year One – to begin your studies, you’ll choose a research advisor and take your first classes.
• Year Two – next, you’ll probably form an advisory committee, finish your classes, and take qualifying exams.
• Year Three – after that, you may be ready to submit your application for PhD candidacy and begin your dissertation process.
• Remaining Years – the remainder of your time will likely be spent conducting and presenting research and writing and defending your dissertation.

It’s important to note that your timeline will vary depending on your dissertation requirement (or lack of it). While most PhDs do require a dissertation, a professional doctor program does not require a doctoral thesis or dissertation , but will often instead offer a capstone project option.

After completing these steps, you can apply for graduation from your program.

Some universities offer part time PhD in Computer Science programs, but these will of course take longer to complete than programs requiring full time attendance.

How Much Does a PhD in Computer Science Make?

Salaries for people with computer science doctorates can vary widely depending on their particular job or field of expertise, their experience, and where they live in the U.S. For example, corporate information systems managers, on average, earn nearly twice as much as professors.

According to the Bureau of Labor Statistics, among information systems managers , those who earn the least make less than $87,480 each year. The 10% with the highest wages bring in over $208,000 annually.

Average salaries are highest in California, New York, and Texas. Those who are employed by clothing retailers, financial establishments, and electronics manufacturers may bring in some of the top earnings.

Which University is Best for PhD in Computer Science?

Picking the best university for your doctoral program is a big decision compared to that of picking a university for, lets say, an online computer science associate degree . Rather, it’s a matter of finding the program that’s the best fit for your personal goals and interests.

You should look for a university that is accredited and where the faculty’s research interests line up with your own so that they’ll be qualified to spur you on toward a greater understanding of your chosen subject area. Additionally, you may want to look for faculty members who have professional connections to industry partners that intrigue you.

Finally, for schedule flexibility, consider schools with online programs.

Is an Online PhD Computer Science Degree Worth It?

Yes, an online PhD computer science degree is worth it for many students. The Bureau of Labor Statistics is projecting 11% job growth in computer and information technology occupations over the next 10 years.

If you're considering graduate school in Computer Science

Considering graduate school in Computer Science? A good place to start is to talk with one of your CS Profs that you know well. In the meantime, here are some general thoughts on graduate school in computer science.

Frequently Asked Questions About Graduate School

Why (or why not) grad school, how long does it take, what will i do after getting a ms or phd, should i work for a while between dartmouth and grad school, how do i pick a list of programs to apply to, how do i pay for grad school.

• What's important to someone evaluating your application

Hints about applying to grad school

• Reflect. Do some soul-searching. Why do you want to go to grad school? Think about your education so far. What are your passions? What are your goals in life? What excites you? What lifestyles might you want?
• Avoid listening to what others tell you to do; think about what you want.
• An MS is basically a technical degree that gives you more interesting job opportunities. A PhD is basically a research degree, which opens up a host of advanced and research-oriented opportunities.
• Think less about how much money you can make but about quality of life. With a PhD in particular, you will often find there is more autonomy, freedom, vacations, travel, influence, creativity, authority, etc. In industry, MS and PhDs are often a ticket to eventual upper-level management.
• Think more broadly than the major or course offerings at Dartmouth. There are other things - computer science, computer engineering, electrical engineering, computer information science, and even some very unusual special things at some places.
• Talk to professors. Discuss your ideas and goals, and get some advice. Talk to some grad students here and elsewhere. Find out what it's like. Talk to recent alum friends about what they've done, why, and how they like it.
• A PhD can be the ticket to jobs in academia, industry, and government, usually in some research or advanced development capacity, or in teaching at the college and graduate level. Or both teaching and research.

What people will want to know about your PhD work is your research. What's it about? How good is it? How likely is it that you will be able to continue being productive in your area?

• Do you like inquiry, invention, creativity, exploration, reading, discussion, writing, thinking, teaching, discovering the unknown, etc? Do you like to work with others, or independently? (Both are big aspects of research.) Do you like to tackle unstructured problems, or would you rather work on a task assigned to you? Do you prefer thinking up new ideas and sketching out the basic fundamentals, or do you like to deal with finishing the details on a project?
• You can always move after getting a Master's degree. Or take a Master's and run--to industry, or to another school.

4-6 years is typical for a PhD. It can take longer, however. I know folks who took 8 or more years for their PhD. 1-2 years is typical for an MS.

• The PhD is basically a research degree. Note that scientific research today does not fit the "lonely scientist" or "lonely hacker" image, either at the graduate or professional level. Scientists--and computer scientists are scientists--do work with people. This is obviously true for teaching, but research is essentially a collaborative exercise. Meeting people and talking to people is a big part of research.
• An MS is essentially a technical degree, especially useful when you are graduating from here with a liberal-arts BA. It will open up a range of much more interesting jobs than you can get with a BA, with more responsibility, creativity, flexibility, and income, than the typical programmer-type job. At least, sooner.
• Opportunities include academia, industry (research and/or development), and government (research labs).
• Postdoctoral appointments are becoming more common. In this case, after your PhD you go elsewhere for 1-2 years to do more research under a different advisor, in a different place, on a different project. Then you would go on to one of the above situations.

This is a very personal issue.

Advantages to working:

• It gives you valuable perspective in grad school.
• Sometimes the company will pay for your schooling.
• Gives you time to consider whether you want grad school at all.
• You can save up some money.

Disadvantages of working:

• You get used to the big fat paycheck, and it's hard to take a 75% pay cut.
• You get out of practice of "going to school".
• If you didn't take GRE as a senior, you forget a lot.
• If you did take GRE as a senior, the scores "expire" after a few years.
• Sometimes you lose "currency" if your job doesn't allow you to learn as you work.

So, if you really know you want grad school, go for it. Otherwise, you might consider working for 2-3 years, and then going to grad school.

• Choose the best programs that you can get into.
• Add 1-2 "safe" schools, that you are pretty sure you'll get into, but you wouldn't hate to be at. Remember that it is possible you'll get into some of your preferred choices, but maybe not with financial support. So, choose good schools, but ones that are perhaps less competitive.
• Pay no attention to the academic reputation of the university. It is essentially irrelevant. What matters is the reputation of the department (program) where you will be applying.
• Read their papers. Are you interested in their research?
• Find Dartmouth alums who are now students there; talk to them or find Dartmouth profs who were grad students there and talk to them.
• Student/faculty ratio.
• Success rate.
• Size of program.
• What will you learn there?
• What is required of you there?
• Who is doing interesting work there?
• Departmental dynamics...is there collaboration? Departments like this tend to be more congenial.
• Placement of recent PhDs.
• Look through journals in your area of interest; find out who is doing work in that area and where they are from.
• Talk to Dartmouth professors who are in the same general field as the one you are interested in. Discuss the schools you are considering. Ask them for suggestions. Ask them about particular professors and programs. They have connections, too, which might get you more information.
• Visit the campus. Tour the facilities. Talk to grad students, especially those who work with someone you're considering as a potential adviser. Try to get a feel for the atmosphere, the morale. This is more important than you realize. Consider things such as office space, library support, computing facilities, special research labs or computers, etc. These are important when you try to do research. Try to talk to the relevant professors. Consider the locale, and the cost of living.
• Big, famous schools are not necessarily better. In a big place you might have trouble standing out. Consider being a big fish in a small pond. On the other hand, small places can sometimes be somewhat limiting in terms of resources and variety.
• Many terminal-Master's programs (those where you are not planning to get a PhD, just a Master's) require you to pay tuition and fees. Note that many big companies will pay all this for their employees, sometimes on a part-time basis and sometimes as a year off for school, while still paying you that same huge salary! It's an option. (Same for PhD, too, though a part-time PhD takes forever!)
• Teaching assistantship (TA): You have to help run labs, tutor, grade, or even teach. First-year students rarely actually teach.
• Research assistantship (RA): You help a particular professor with their research, usually supported by a grant.
• Fellowship: This is the best. Usually this gives you all the money but with no teaching or research opportunities. Some schools do this for many of their first-year students, with the expectation that you will become a TA or RA in later years. A really good deal gives this to you for 3 or 4 or 5 years.
• Definitely plan to apply for third-party fellowships. Many require you to be a US Citizen, but not all. If you can get one of these, they often pay more, usually don't require any teaching or other duties, and you can call up the schools and tell them you have your own funds...which they are definitely psyched about. It also looks great on your resume in the future.
• One thing to know is that your guaranteed student loans (GSLs) are deferred (interest-free) so you don't have to pay them while you're a full-time student. So when you graduate from grad school, and have a big fat paycheck, and inflation has reduced your loans to a fraction of their former value, then you pay them off.

What's important to someone evaluating your application

• For most letters, you have a choice of whether to waive your right to see the letter. You should always waive this right. Yes, it may bother you greatly to waive any right, but think about it this way. If you do not waive this right, then your letter writers will not be able to write about you in confidence. Your letter readers will know this, and the letters about you will be discounted. In essence, the one subjective source of information on you has become worthless. So make sure you waive your right to see your letters.
• If you can, include something that makes you special, like a paper you wrote or the description of a programming project or the like. These "appendices" are perfectly fine and will often really make a big difference. Do not send a printout of code. But you might consider pointing to a cool program you wrote, say on github, if you really have something to show for it. Most people won't bother to try it, but they might if you make it easy for them.
• Test scores and grades are somewhat important; bad scores and grades are enough to keep you out, but great scores and grades are not enough to get you in.
• The essay is moderately important; in particular, it had better not be bad. The best essays somehow set you apart. Write your essay carefully, and rewrite it again and again. Tell them what research areas you are interested in, and why. Make it clear that you have a passion for research and would gladly charge through a machine-gun nest for the privilege of doing research. Tune the essay for each place you apply; tell them why you want to go there. Get the essay read over by someone else; make sure it is written really well. Sell yourself! Tell them what makes you unique. If you have written a research paper, or a major computer project, send them the paper (or documentation, if reasonable), perhaps after cleaning it up by making it even better.
• Start early: senior fall, or even junior summer.
• Write to lots of departments and request informational brochures and application materials.
• Take the GREs in October, or at least in December, and have the scores forwarded directly to the schools where you are applying.
• Request transcripts and have them directly forwarded.
• Send in your application well before the deadline.
• Follow up on everything. If you're using snail-mail, be paranoid.  (Who uses snail-mail anymore?) For example, send your application materials return-receipt-requested, and include a self-addressed, prestamped postcard that says "XXX university has received my materials", so that you know when they have arrived. Call them if you do not receive this. Especially: followup on faculty letters of recommendation (be tactful of course), regardless of whether they are submitted electronically or physically.
• Ask for your letters of recommendation early, October if you can. Go ahead and ask even before you have all the forms they will need, or even before you know the complete list of places you will apply. They can start writing the letter and then mail it when you give them the materials. Ask for the letters in person if possible - talk with the prof for a little while. (Make sure they remember who you are! Obviously, you want someone who really knows you well.)
