In the California State University system, a campus is designated as “impacted” when the number of applications received from qualified students exceeds the number of available spaces. It also means that a campus has exhausted its instructional resources and physical capacity. The final admissions thresholds are determined after the application period has been closed and after receiving all of the undergraduate application for admissions. Those campuses are permitted to use supplementary admission criteria to screen applications.[1]

Business Rules
