The University may impose limits on the number of units for which a student can register during each registration period. To learn about these Academic Load Regulations, visit www.csun.edu/anr/soc/academicpolicies.html. Students wishing to exceed the maximum unit load after the Registration-by-Appointment period must complete and file an Extra Unit Authorization form with Admissions and Records. There also are restrictions for students based on their academic status. Students on academic probation and undergraduates readmitted under Academic Performance Agreement are limited to 13 units.
