Computing technology has become an essential part of nearly every profession even as new research in computer science continues to reinvent how we communicate and work. The computer science major at Bethel prepares students to be leaders in this ever-changing academic discipline as they learn current programming languages, network technology, databases, software engineering techniques, hardware, and operating systems. Electives are also offered in graphics, compilers, artificial intelligence, and high-performance computing. Students can gain work experience through employment in Bethel’s computing support services and can earn course credit through internships at local companies. Bethel conforms to the Association for Computing Machinery (ACM) model for a liberal arts university computing degree with coursework in computing ethics and a balance of practical and theoretical study in computer science.

Advanced Placement: The computer science department requires a score of 4 or better on the AP exam in order for the exam to be used to fulfill course requirements in the majors and minors it offers. Students with a score of 3 will receive elective credit or receive credit toward General Education requirements. Students should consult the department chair with questions on AP exams and requirements for majors.
