Choosing a Computer Science Program

Since the field of computer science is a STEM field, it’s important to choose the right program. You don’t want to earn a bachelor’s degree for the sake of it. Instead, you want to enroll in a program that provides a well-rounded, high-quality computer science education.

Here are the crucial considerations when choosing from undergraduate computer science degree programs.

Regional and Programmatic Accreditation

Accreditation means the university and program comply with standards of quality, among other criteria. Plus, regional accreditation means access to federal and state student aid programs.

  • Check with the CHEA for the accreditation status of the college or university.
  • Consider programmatic accreditation by the ABET (Accreditation Board for Engineering and Technology).

Look beyond accreditation and consider the program’s reputation in the academic community.

Cost of Education and Financial Aid

The cost of a bachelor’s degree can be a challenge. Tuition and fees vary widely, from $13,430 at the University of Florida to $98,055 at Northwestern University.

  • Be cautious about the sticker price. Consider incidental and living expenses as an on-campus or off-campus student.
  • Research the financial aid programs available.
  • File your FAFSA early.

With proper financial planning, cost should be less of a headache.

Curriculum Quality

Check out the classes required for a computer science degree. You can decide if the curriculum meets your academic needs by:

  • Getting information from the academic catalog. Read the course descriptions and outcomes.
  • Ask current students, if possible, about their learning experiences. Get insights that will inform your decision.

The best programs have an interdisciplinary approach in their curriculum. A well-rounded computer science education emphasizes both hard and soft skills. The interdisciplinary approach ensures that students develop both types of skills through didactic coursework and hands-on learning.

The curriculum focus will also vary depending on whether it’s a BA or a BS degree. With a BA degree, the focus is on soft skills development without compromising hard skills acquisition. In a BS degree program, there’s more emphasis on science and hard skills.

Class Size

If you thrive with personalized attention, consider small class sizes. But being another face in a sea of faces has its merits, too. In this case, go for large class sizes.

Most programs have a mix of these two types depending on the course. Students may, for example, be in large lecture halls for lectures. Then, they will switch to small groups during laboratory sessions and design projects. 

Faculty Expertise

The quality of your computer science education will depend on the expertise and experience of your professors. You must then consider their professional credentials.

  • Check their academic attainments, industry experience, and scholarly endeavors. You can check the official website or request more information.
  • Connect with the faculty members you’re interested in. Many colleges allow it.

Don’t be shy, either. If you get accepted, you will learn under their tutelage.

Facilities and Resources

Both on-campus and online students must consider the availability, quality, and accessibility of the campus facilities and resources.

  • Make a campus tour. Check out the classrooms and computer laboratories.
  • Get acquainted with the learning resources, too. Libraries and study spaces should be sufficient.
  • Get a feel for campus life.

Remember that college will be your second home. Look at its facilities and resources as if these will be yours to enjoy.

Student Support Services

Your academic success will also depend on the quality, accessibility, and availability of student support services. Be sure to look for these services:

  • Admission assistance
  • Financial aid assistance
  • Mental health services
  • Writing and math centers
  • Tutoring services
  • Career development services

Your college experience shouldn’t be limited to academics either. Check out the student life opportunities, such as Greek letter societies and sports teams.

Learning Format

You should also consider whether you want to be an on-campus or online student. Many universities offer both on-campus and online formats, such as the University of North Dakota.

Your choice between these learning formats will depend on your learning style, work-life balance, and lifestyle. If you’re a working student, you may prefer the online learning format for its flexibility and convenience.

Avoid making a hasty decision. You should discuss your options with your parents and mentors, if possible. By getting their opinions, you will get another perspective.
