Graduate-program decision makers face a similar challenge: how to design an admissions process that screens out applicants who are unlikely to succeed but does not provide too high an entry barrier for students who can be successful. This study catalogs the use of standardized testing in Master of Public Administration admissions and finds that less than one third of programs require standardized tests for all applicants. Moreover, program prestige, program diversity, and program size do not affect the likelihood that a program requires the Graduate Record Examination. This study also reviews the various standards that universities use to provide test waivers and also discusses other common application materials. The results should be of interest to undergraduate academic advisers and graduate-program directors as well as scholars and practitioners of higher-education administration more generally.
