The article examines the extent to which first-time associate's and bachelor's degree students change their majors within 3 years of enrollment. Rates of change in major are shown for students by degree program and by original declared field of study. Data in this report are from the 2012/14 Beginning Postsecondary Students Longitudinal Study (BPS:12/14), a nationally representative study of about 25,000 students who enrolled in postsecondary education for the first time in the 2011-2012 academic year. These analyses are restricted to students who had ever enrolled in an associate's or bachelor's degree program and declared a major within 3 years of initial enrollment. Students with declared majors represent a majority in both associate's (94 percent) and bachelor's (97 percent) degree programs (NCES 2017).
