This study looked at 1992 high school seniors to see how many of them would have met the new National Collegiate Athletic Association's (NCAA) Proposition 16 eligibility requirements for freshman participation in Division I college varsity sports. The new, stricter requirements are based on a combination of the high school grade point average in 13 core courses and specified Scholastic Assessment Test or American College Testing Program scores. These requirements were applied to the transcripts of a National Education Longitudinal Study of 1988 sample of 1992 college-bound high school seniors. Findings revealed that: (1) 83.2 percent met earlier NCAA standards while only 64.7 percent met the Proposition 16 requirements; (2) only 46.4 percent of black and 54.1 percent of Hispanic students in the sample met the stricter requirements as compared to 67 percent of white and Asian seniors; (3) college-bound high school seniors from the lowest of the socioeconomic status levels were the least likely to meet the requirements with only 42 percent qualifying to participate; and (4) college-bound high school athletes met the requirements at the same rate as non-athletes. Contains two tables and five figures. (Author/JB)
