An ESP is an early student progress report. You can find the information online on the Allen website under current students, then resources and then student handbook, the early student progress report
Grades are issued at the close of each semester; however, a progress report may be issued anytime to inform a student of his or her status in class. The Early Student Progress Report (ESP) will be available through campus email, and follow-up will be provided through Student Services. Suggestions and resources may be recommended to help improve the student's academic performance, if needed.
