The BA and BS are two popular undergraduate degrees. A BA is a bachelor of arts, and a BS is a bachelor of science. Keep reading to learn everything you need to know about the differences between BA and BS degrees.
BA vs. BS: What's the difference?
The main difference between a program that awards a BA vs. one that confers a BS is the focus area of the curriculum. While BA programs usually approach a subject from a humanities perspective, BS programs generally focus on math, science, and/or technology.
If you want to pursue a career in a scientific or technical field, a BS may be a good choice. On the other hand, a BA usually involves studying a liberal arts subject, such as the social sciences, philosophy, or literature. BA courses of study typically let you take more electives than you could in a BS degree program.
Understand time commitments
Both BA and BS degree programs usually take four years to complete. However, the length of time it takes to earn your BA or BS depends on the program and how much flexibility it provides. If you're a part-time student, for example, it may take you more than four years to earn your degree.
Review admission requirements
Every program has unique admission requirements. These requirements vary depending on the subject and institution. However, most programs — whether they confer BA or BS degrees — share core requirements: Students typically must fill out an application, possess a high school or GED diploma, send in letters of recommendation, and possibly submit standardized test scores. Once you've chosen the BA or BS program you're most interested in, go to the program page to learn more about admission requirements and how to apply.
BA vs. BS costs
BA and BS costs vary by institution. As BS degrees can sometimes involve lab work, there may be additional costs related to these requirements. Science and technology programs are often popular at many institutions, which may also impact the tuition rates for BS degrees.
BA vs. BS coursework
As most science and math subjects confer BS degrees, these programs tend to involve more technical, hands-on courses (such as lab work). In a BS program, you may be required to take more classes focused on your major than you would in a BA program.
In an English, gender studies, or history program — courses of study that typically confer BA degrees — you will probably spend a lot of time developing and refining your critical thinking and communication skills.
BA vs. BS: Which should you choose?
To choose a BA or BS program, consider your goals. If your goal is a career in math, science, or a technical field, a BS may be a good choice. On the other hand, BA degrees typically focus on the humanities, social sciences, or modern languages. If you want to study one of those areas, consider a BA program.
BA programs usually allow you to take more elective courses than BS programs. That can make them a good choice if you haven't made up your mind about your career objectives.
