Considerable attention has been paid to factors affecting student's selection of Engineering and related majors [1,3,5] and issues affecting retention and graduation in these majors [4,7]. Lesser attention has been paid to change of major policies and their effects [2].We study the history and effects of "change of major" policies in the Erik Jonsson School of Engineering and Computer Science at the University of Texas at Dallas. We further focus on two closely related degree programs (Computer Science and Computer Engineering) that are delivered by different departments within the School. A university-wide policy that just required "good standing" to change major up to four years ago has evolved into separate policies for multiple Schools that have become more restrictive over the years and especially so in the School of Engineering and Computer Science. Motivations for the policy and the updates to it included managing growth and maintaining, improving quality.We look at a number of issues arising from the policies and the interplay between the School's change of major policy and policies at the University level. We study movement of students in and out of the School and each Department and its effects. We discuss issues with maintaining a common School-wide policy on change of major and the effects on the Departments.
