Earning an Online PhD in Computer Science
Online degree programs are not new; they have been implemented with more and more frequency since the early ’90s. The reason that these programs continue to grow in popularity is that they are excellent options for a lot of people, especially working professionals. When you have an established job or family or both, it can be nerve-wracking to consider going back to school because of the time investment, the money, or even the idea of relocating just to go to school.
Studying online allows you to stay where you are. You won’t have to relocate to continue your education. Some of these programs will have residencies, but those are typically structured in such a way that they don’t interrupt your lifestyle. Many online programs are asynchronous, so you can essentially set your own schedule. They are also associated with lower costs because you don’t have to move and you will probably have fewer costs such as supplies, fees, and so on.
There are very few universities across America that currently offer this type of degree, so we have done the research to find them for you and created this ranking of the Top 5 Online PhDs in Computer Science. They were ranked according to the following.
Colleges and universities which were examined for our ranking include not-for-profit private schools as well as public institutions. Data for the ranking is gathered from multiple sources which include the following:
Colleges and Universities were ranked based on four different numbers: overall graduation rate, retention rate, residential cost of attendance (COA), and the overall grade given by students at Niche. Graduation rate and retention rate, we dropped the percent for ease of addition. For example, 64% would become 64. No institution is expected to achieve a total score of 400, however, each of these numbers can be as high as 100.
These conversion scales explain how affordability is ranked from the COA. Also, you can find out the way we have converted Niche grades into a number. After converting these statistics into our numerical scale, all four numbers are added together in order to get a total score in order to rank the school.
While it’s true that many perceive graduation and retention rates as not as important for graduate students, they are a good way to assess the overall success of an institution, and this is why these statistics were chosen as part of our ranking criteria.
Cost of attendance is how we measure the affordability of an institution. While some institutions may have different rates for residential students versus out-of-state students, the residential COA was chosen to use for our ranking.
The Niche overall grade is a grade that has been determined by students who use Niche and voice their opinions and sometimes recount their experiences.Student opinion is important to OnlineCollegePlan and thanks to data from Niche, we are able to use their measurement and convert it into a numerical form. This allows data from actual students to create our ranking.
The ranking formula is:
Graduation Rate + Retention Rate + COA + Niche Grade = Final Score
It should be noted that no schools ranked on OnlineCollegePlan have given preferential treatment, nor have any institutions requested such. Our rankings are prepared as explained so that any individual would be able to create the same rankings using the same data from these sources in order to arrive at the same sequence at the time of publication. OCP can not be responsible for changes in data which occur after the ranking is created, however, we strive to keep our rankings updated and current.

As for actually earning the PhD in Computer Science, the requirements are still varied but not as much. PhD programs require you to complete around 60 or more credits in coursework. Alongside your coursework, you will also conduct research, and subsequently complete and defend a dissertation. The dissertation process includes a proposal, your research, typically guided research with a faculty advisor along with independent research, and then a defense. That is the basic process.
Schools will detail any required prerequisite courses that you must have completed. There are typically more requirements placed on those who haven’t completed a master’s degree, which is why having some graduate-level study is encouraged and tends to be preferred by a lot of universities. For those students who haven’t completed those classes, you may have the opportunity to take them prior to full admission to your chosen PhD program.
Once you’re in the program, your coursework will cover advanced topics in computer science. Not every school is going to offer the same courses or place the same requirements on you. It is typical that most computer science PhD programs require you to take courses in math, programming languages, architecture and systems, and more. You will also probably choose an area of focus for your degree, and have a course requirement to meet within that chosen area.
Along with a dissertation, the typical doctorate degree program also has a comprehensive examination you’ll have to pass in order to graduate. This is typically broken into a written and oral component.
Like we said, each institution is going to have an individual set of requirements, and you should explore those thoroughly when selecting the best program for you.
