Computer Information Systems Major

The Bachelor of Arts in Computer Information Systems (CIS) provides an educational foundation for students planning a career in the analysis, design, and implementation of information systems. Students are prepared for careers as systems analysts, application software developers, and information technology specialists. Students who have a strong interest in technology and its application, but are not primarily interested in the scientific and mathematical aspects of computer science, should find this program a good fit.

Information systems (IS) is the study of the application of computer technology in organizations. It is founded on two major reference disciplines, computer science and management. Unlike computer science students, IS undergraduates must complete some accounting and finance coursework. IS involves no coursework in engineering or scientific computing, and the mathematics courses are practical and applied. Traditionally, IS undergraduate curriculum focuses on managing information systems (the business side of IS); APU’s CIS program emphasizes the application of computer technology to information systems.

To be successful in this major, knowledge of operating systems, word processing, spreadsheets, and database applications is recommended. 

Career Opportunities

The Bachelor of Arts in Computer Information Systems prepares students for advanced studies in such fields as computer information systems, computer engineering, computer security, and telecommunications. Due to the rapidly changing technical and scientific technology in computer information systems, students are encouraged to enter a graduate program soon after completing a bachelor’s degree program.  

The CIS program also offers internship opportunities to prepare students for careers in the field following graduation. The program connects students with internships at several local, national, and international businesses and organizations. These organizations regularly return to APU seeking students for internships and employment. Employment opportunities in the areas of system networking, database management, telecommunication, and web programming are in abundance. 


In addition to the General Education requirements, a minimum of 47 computer information systems units, 3 mathematics units, and 7 business units (for a total of 57 units) are required for the Bachelor of Arts in Computer Information Systems.
