City College began charging tuition in 1976. In 1999, the CUNY Board of Trustees voted to eliminate remedial classes at all CUNYs Senior Colleges, thereby eliminating a central pillar of the policy of Open Admissions and effectively ending it.  Students who could not meet the academic entrance requirements for CUNY's Senior Colleges were forced to enroll in the system's community colleges, where they could prepare for an eventual transfer to one of the 4-year institutions. Since this decision, all CUNY senior colleges, especially CCNY, have begun to rise in prestige nationally, as evinced by school rankings and incoming freshman GPA and SAT scores. In addition, the end of open admissions sparked a change in CUNY's student demographics, with the number of Black and Hispanic students decreasing and the number of White and Asians students increasing.
