Computing Career Change Opportunity

Your new career starts now with a Computing Career Change Opportunity

Learn the skills needed to make a career change into the thriving digital economy. The Master of Science in Computer and Information Science program with the Computing Career Change Opportunity provides students a smooth transition from a liberal arts or science background to a career in Computer and Information Science. 

The Career Change Opportunity begins with a study of the Foundations of Computing to prepare you for our MS in Computer and Information Science program. Students in this program must enroll in 35 additional credits after the Foundations course and meet all of the graduation requirements to complete the program.

In addition to the Foundations of Computing, students have the option to or add a specialization in cyber security through information assurance and cyber defense or to customize their curriculum. 

Career Opportunities

  • Application Developer/Programmer
  • Software Engineer
  • Cyber Security Specialist
  • Systems Analyst
  • Enterprise/Solutions Architect
  • Big Data Analytics
  • Business Intelligence Engineer

Our M.S. in computer and information science program is a STEM-designated program, which means international students are eligible to apply for 36 months of Optional Practical Training, allowing employers to potentially hire international students for up to three years instead of only one.

Flexible Class Options, Learning Outcomes

Computer and Information Science is a broad-based family of disciplines that includes computer science, computer engineering, software engineering, information systems and information technology. The Computer and Information Science master's program allows the student to pursue studies in any combination of these disciplines. Students may pursue the degree on a full-time or part-time basis with many courses offered in the evenings and online.

Career Outcomes

The flexibility of the MS in Computer and Information Science program allows you to shape a course of study that matches your career interests and goals. You choose courses from any graduate program on campus that relates to Computer and Information Science and your career goals. This includes the departments found in Arts and Sciences, Engineering, Management, Health, and Nursing, to name a few.

Within the program we believe you ought to have a primary and secondary emphasis in mind that reflects your interests. Your primary career focus should include at least 12 semester hours of work and the secondary career interest should be at least 6 semester hours.

While the MS in Computer and Information Science program offers specializations, we do not require one. Unless you choose one of the specializations, we do not prescribe a set of courses that you must choose. We do offer some suggestions that align well with current career positions.

  • Business Intelligence and Analytics
  • Database Analysis/Administration/Architecture
  • Information Security
  • Mobile Computing
