Undergraduate course withdrawal at the University of Washington has risen from 3.5 percent in fall 1964 to 7 percent in spring 1973. In an attempt to understand the dynamics of withdrawal, the Faculty Council on Academic Standards arranged a survey of students dropping classes in the spring quarter of 1973. It was found that, typically, students were motivated to withdraw by too heavy a course load, which, however, was not acted on until the last two weeks of the quarter. Juniors withdrew more often than other groups. Although, in general, students remained in class long after they were aware of a problem, less than half took any steps to solve it before dropping a course. Numerous graphs illustrate withdrawal trends according to week of withdrawal, class standing, reason for course selection, reason given for withdrawal, and lag between problem onset and withdrawal time.
