This report to the Illinois Board of Higher Education examines the use of tuition waivers to achieve gender equity in intercollegiate athletics as allowed by the state's Public Act 89-166. An introduction explains the context for the law which requires that institutions must demonstrate "substantial proportionality" reflecting the undergraduate enrollment ratio, a "history and continuing practice" supporting the underrepresented gender, or effective accommodation of the interests and abilities of female students. The second section identifies milestones in gender equity in intercollegiate athletics including Title IX of the Higher Education Amendments of 1972, the Gender Equity Report Card which evaluated gender equity among member institutions of the National Collegiate Athletic Association, and the Cohen vs. Brown University court case which ruled in favor of female athletes. The third section examines gender equity in intercollegiate athletics at Illinois public universities specifically emphasizing the effects of Public Act 89-166. The report concludes that Illinois public universities are demonstrating continued progress in complying with Title IX and that tuition waivers are one tool being used to improve gender equity. Tables providing gender equity data for individual Illinois institutions are provided. Appended are the text of relevant sections of Public Act 89-166, a summary of gender equity plans by six Illinois institutions, and additional data tables. (DB)
