The master's programs require 30 to 48 semester hours of course work. In addition to a required research methodology course, each major consists of core and major or concentration requirements. Core requirements provide the theoretical underpinning for future work. Major and concentration requirements allow students to select special areas of interest depending on their professional and personal goals. Additionally, most degree programs have elective requirements. Lastly, each student completes the final program requirements with a comprehensive exam, a thesis or an integrative practicum; the options may vary according to the degree program.
