In 1993, a second annual review was conducted of the 1990 State Regents admission policy for the Oklahoma State System of higher education. The review was intended to assure institutional policy compliance, ascertain the effects of increased admission standards on institutional student profiles, and evaluate whether the ultimate goal of maximizing student success was being achieved. In keeping with the 1990 policy, both the University of Oklahoma (UO) and the Oklahoma State University (OSU) are experiencing a stair-step increase in admission standards. In the fall of 1991, to enter the OSU or UO, a student was required to have a 21 or higher American College Test (ACT) score, or rank in the top 40 percent and have a minimum 3.0 (4-point scale) high school grade point average (GPA). Study findings included the following: (1) from fall 1991 to fall 1992 total enrollment reached 163,988, representing a 2.8% increase, while first-time entering freshman enrollment increased by 4.3% for OSU, 4.1% for UO, and 7.9% for the two-year schools; (2) the comprehensive and regional institutions are not receiving as large a market share of high school graduates as they were six years ago, with two-year institutions absorbing their enrollment losses; (3) among fall 1992 first-time entering freshmen, 58% of those admitted to both comprehensive and regional institutions met all three criteria (ACT, rank, and GPA) for the appropriate tier; (4) systemwide attrition rates declined from fall 1987 to fall 1992; and (5) from 1987 to 1992, minority student enrollment increased from 16.7% to 23.3%.
