The 12-month Enrollment count is the unduplicated headcount of students enrolled over a 12-month period. Because this enrollment measure encompasses an entire year, it provides a more complete picture of the number of students at non-traditional institutions that enroll students year round or for short-term programs.
Data collected include:
- Unduplicated headcounts by level of student, race/ethnicity, and gender;
- Instructional activity (total hours students are engaged in instruction); and
- Full-time equivalent (FTE) enrollment (calculated based on instructional activity).
FTE provides a meaningful combination of full- and part-time students across institutions that operate on different calendar systems and is used to calculate expenses per FTE and revenues per FTE.
