Tradition suggests that college students should invest two hours in study for every hour of classes. The reality — that students miss that goal by half — emerged from the National Survey of Student Engagement, a research tool for colleges that examines the modern student in unprecedented detail. The survey, first published in 2000, queries freshmen and seniors. It reveals that study time can vary widely by college and by major. Architecture majors, for example, study 24 hours a week, while marketing majors put in only 12. Colleges are not required to publish survey results. The Washington Post asked prominent colleges in Maryland, Virginia and the District to disclose their survey data on study time. Only at Washington and Lee University, in Virginia, did students report as many as 20 hours of weekly study.
