Accreditation is critical for any educational institute. It certifies that the school and its curriculum meet the appropriate standards outlined by the U.S. Department of Education and/or the Council for Higher Education accreditation. Choosing an accredited school gives your degree the credibility and validity required by employers. 

Many programs and departments within a school may have a separate certificate of programmatic accreditation. This elevates the credibility of the program and showcases that the department has designed a program that meets a standard of excellence. 

Programmatic accreditation also ensures that students will receive the appropriate training and knowledge to be successful in their given fields. 

Applying To Online Computer Science Programs

Admissions requirements for online computer science programs depend on the type of school, degree, and program modality desired. Prerequisite classes, letters of recommendation, certifications, degrees, GRE results, and prior grades are a few examples of typical computer science major application requirements

Admissions Requirements for Computer Science Major Programs

Admission requirements vary greatly from school to school and from program to program. There are also different requirements for undergraduate programs than for grad school. Many master’s degree program applicants must not only apply to the grad school itself, but also need to be accepted into the actual CS program. Below are some of the most common requirements for bachelor’s and master’s programs. 

If applying to an undergraduate (certificate, associate’s, or bachelor’s) program:

The most obvious requirement to apply for any college program is to have first graduated high school (or obtained a diploma equivalent, such as a GED).
Ready to apply to a computer science program? You’ll need a strong GPA to be competitive! If a program lists a minimum of a 2.5 GPA to qualify, that just means they won’t consider anything less…but the actual cutoff could be much higher, because it depends on how many other people applied and what their GPAs look like. Try to find out the average cutoffs from previous cycles to learn what the actual average GPA was for those who got accepted.
Many schools want one or more recommendation letters, ideally from someone who has knowledge about your CS skills and academic potential. The school wants these to help assess your ability to stick with the program, contribute while there, and graduate in a timely manner.
Statements of purpose (SoPs) are also common application requirements. They help the school get a better sense of each student’s personal history and goals. Some schools list questions or an essay prompt that must be used to complete the SoP, so don’t just recycle the same statement over and over, if you apply to multiple programs. 
Colleges need transcripts from high school along with any transcripts from previous colleges or schools you may have attended. Generally, they want official, sealed transcripts mailed directly from the school to them. That process can take a little while, so don’t wait until the last minute to order official transcripts.
Most programs charge a non-refundable application fee. This fee is sometimes waivable. Fees can add up quickly if you apply to many schools, so always see if you qualify for a fee waiver.


 If applying to a graduate (master’s or doctorate) program:

To get into grad school, you need a bachelor’s, obviously. But what about your major? Graduate-level computer science major don’t demand that you majored in computer science during your undergrad studies, but they do need you to have completed sufficient prerequisite coursework. If you don’t have that done, you can still apply but will likely have to earn those credits before being fully accepted into the program.
Most computer science programs want applicants to submit Graduate Record Examination (GRE) scores. Some schools may waive these or not request them at all. Some temporarily waived them during the peak of the Covid pandemic. Make sure to double check before applying!
CS graduate programs are tough to get into. They don’t just want students who will come take classes then leave. They want professionals who will contribute to the department, which is why they ask for additional information related to your background via a resume or CV! Take the time to write this document in a compelling manner and make sure it is error-free.
Another way computer science programs like to get to know applicants is through a formal interview process. Again, your success at their school reflects back on them. That is why, if you notice, many schools publish their graduation rates and stats about how quickly graduates are placed in jobs. Those are “selling points” that attract more applicants!

Paying For An Online Computer Science Degree

Deciding to go back to school is not only a big-time commitment, but it is also a big financial commitment. Tuition costs can vary depending on the school, program, required units, and projects. 

There are many avenues of financial assistance available to help with tuition costs including financial aid, scholarships, grants, internships, work-study programs, and corporate reimbursement from your current company. 

  • Financial aid - The process is typically the same for online or campus-based programs. You can take advantage of federal, state, or school based financial aid programs that usually range from merit-based to needs-based assistance by completing your FAFSA.

  • Scholarships - There are an abundance of organizations that offer scholarships specifically for computer science students to help supplement tuition costs. Unlike loans, scholarships do not need to be repaid. More detail on scholarships is provided in the next section and available with our scholarship search tool

  • Grants - Applying for a grant is a great way to raise funds for your education, and like scholarships do not need to be repaid. Consider applying for a Federal Pell Grant or a Federal Supplemental Educational Opportunity Grant. State and local government, universities, and non-profit organizations are also great places to look for grant opportunities.

  • Internships - Compliment your resume and work experience with an internship. Paid internship opportunities are dependent on the company or institution but offer experience and knowledge while getting paid!

  • Corporate reimbursement programs -  If you are currently employed, check with your human resources department to see if educational reimbursement programs are available to you as an employee benefit. 

Scholarships For Computer Science Students

Many scholarship opportunities are available for computer science students.  Here are a few avenues to consider.

Next Steps to Get Started in a Computer Science Program

Ready to start prepping your application to a competitive CS program? Your entry point onto the right educational path depends on where you’re at now!

For High School Students:

If you’re still in high school, there are things you can do to set yourself up for success as a computer science major in college.

Many high school students want to breeze through and put off the hard work for college itself. Unfortunately, that can be a recipe for failure. College is often much harder than a lot of high school students expect. Computer science, in particular, is a very challenging major. 

That’s why you want to lay a solid foundation to build upon by taking classes in high school that will aid you in your CS program. These classes include any computer science and IT courses offered, as well as digital design, science, math (including geometry, trigonometry, precalculus, and calculus), physics, typing, and speech.

Not every high school features a computer science club. If you’re lucky enough to have one, join it and stay engaged. If your high school doesn’t have one, consider starting it yourself! 

Clubs are a fun way to keep each other motivated, and an incredible method of learning new skills. There are plenty of open source materials to help you get started or augment an existing CS community.

Most high schools don’t offer computer science specific classes. That lack of access, which hits rural and urban students the hardest, can be a setback for those who want to study computer science at college. 

But students can teach themselves many of the foundational skills needed, through free or relatively inexpensive online courses.

For High School Graduates: 

High school seniors who want to go to college right away need to apply early and often. Make a list of the schools/programs that interest you, and check out the application deadlines. Many get started during the summer before their senior year, then start applying during their Fall term.

Once you’ve finished high school or earned a GED, and you’ve been accepted into a CS program, then you’re on your way to getting that bachelor’s degree!

A bachelor’s typically takes four years, if attending full-time. Part-time students may take up to twice as long. It’s important to check with the school to see if there is a maximum time limit to complete all degree requirements. 

If you’re thinking about earning a master’s next, make sure to keep up your GPA. Graduate school can be even more competitive than getting into an undergrad program!

For Bachelor’s Degree Holders: 

If you don’t want to go back to college just yet, consider signing up for a certification program related to the area you want to continue your studies in. There are dozens of options offered by numerous organizations. Below are just a few examples

As mentioned above, a college certificate is not the same thing as a certification. Certifications are usually acquired by studying material, then taking and passing an exam. College certs, on the other hand, are like miniature degrees, which require passing a certain number of regular college classes (usually between 12 - 18 credits’ worth) that all tie into a particular area of CS specialization.

If you’re ready to get back into the thick of things, a master’s degree can really boost your professional credentials and help qualify you for higher levels of responsibility - and with it, a higher salary! 

But if you’re already working, talk with your supervisor and get some feedback about which option is best suited for your career advancement. Sometimes a worker with an in-demand certification can be more important to an employer’s immediate needs than someone with a graduate degree. 

Of course, nothing is stopping you from doing all three of the above options, if that suits your career path!
