What Kinds of Computer Science Degrees Are There?

Computer science degrees are available at all levels, and can lead to a wide range of lucrative, in-demand jobs. Whether you want to gain practical skills and quickly enter the tech workforce, or engage in a lifelong study of cutting edge technology, there’s something out there for you.

  • Associate in Computer Science (AA or AS): An associate in computer science typically takes two years to complete and requires 60 credits, though accelerated options are sometimes available. These programs develop foundational knowledge in computer science, and sometimes provide light specialization in areas like web or software development. Coursework includes security, networking, algorithms, programming, and database management. With an associate in computer science, you can gain employment in entry-level roles such as web developer, computer repair technician, or computer support specialist, and are ready to pursue further education in a bachelor’s degree program.
  • Bachelor of Computer Science (BA or BS): A bachelor of computer science degree typically takes four years to complete and requires 120 credits, though accelerated options are sometimes available. These programs typically include courses such as algorithms and data structure, computer programming, operating systems, and computer systems networking, as well as a professional experience component, lab component, and research component. Also, they often include specialization tracks, such as computer engineering, artificial intelligence, data science and analysis, or systems networking. With a bachelor’s in computer science, you can gain employment in well-paying entry-level roles such as computer network architect, computer programmer, computer systems analyst, information security analyst, or computer systems administrator. You would also be eligible to pursue further education in a master’s degree program.
  • Master of Computer Science (MA or MS): A master of computer science typically takes two years to complete and requires 30-45 credits. Courses in these programs often include machine learning, artificial intelligence, applied cryptography, data systems, analytics, and computational statistics. Additionally, these programs will require students to specialize in areas such as computer networking, computer research, computer engineering, artificial intelligence, or data science. You will also have to complete a research or thesis project, and likely a professional experience component. With a master’s in computer science, you’re prepared for high-paying and advanced roles in the field, including computer engineer, computer and information research scientist, software developer, and data scientist.
  • PhD in Computer Science: The highest degree you can earn in the field, a PhD in computer science typically takes three to five years to complete. This terminal degree will typically require a combination of advanced coursework, a research project and dissertation, comprehensive exams, and lab or instructional work. At this level, you will already be well into your specialization area. Therefore, you may need to determine where to earn your doctoral degree based on how each school ranks for your specialization. With a PhD, you can pursue the most advanced professions in the field, including computer and information research scientist, and post-secondary educator in computer science.

*Note: Many, but not all, degree programs offer the choice between Bachelor of Arts and Bachelor of Science degrees. Likewise, many, but not all, advanced degree programs offer a choice between Master of Arts, and Master of Science degrees. In most cases, the primary difference is the diversity of course offerings. “Science” degree courses will focus almost entirely on the major discipline, with a deep dive into a specific concentration, including laboratory, clinical or practicum experience. An “Arts” degree will provide a more well-rounded curriculum which includes both core/concentration courses and a selection of humanities and electives. The type of degree you choose will depend both on your school’s offerings and your career/educational goals. Moreover, there are sometimes numerous variations in the way that colleges name and categorize majors. The degree types identified here above are some of the common naming variations, but may not be all-encompassing.
