The three case studies in this report describe state-level efforts to address diversity and equity in postsecondary institutions in California, Maryland, and Washington. A preface provides some background on affirmative action programs, litigation history, and the roles of state coordinating agencies and institutional governing boards. The California case study titled, "Planning for Growth and Diversity in California" (Charles A. Ratliff), reviews the history of the state's public higher education policy, and discusses its demographic growth, the fiscal constraints on enrollment, its long-term commitment to educational opportunities, problems of access and diversity, future actions, and evaluation methods. The text is augmented by five displays. "Developing New Strategies for Enhancing Access to College in Maryland" (Howard P. Rawlings and Sheila Ards) reviews the history of Maryland's formerly segregated public higher education system, notes current policies and strategies used to promote access, and also discusses K-12 strategies for improvement. "College Admissions Standards and Equity in Washington" (Jane Sherman) sets out the context of the state's educational history, discusses how the state monitors admissions and diversity, and notes future steps. Five data tables are included. (All the reports contain references.) (CH)
