The National Survey of Student Engagement is an annual survey administered since 2000.
Another result, as described by the Times:
Money troubles interfere with the academic performance of about one-third of all college students, and a similar number of students regularly skip buying required academic materials because of the costs, according to a survey released on Thursday.
