This five-part report presents a statewide framework for assessing the impact of intersegmental programs designed to enhance student preparation for college, particularly those students who are historically underrepresented in postsecondary education. The first part of the report explains the origins of the study and the organization of the report, and the second part describes the eligibility rates for public universities and the community and school contexts. Part 3 summarizes the characteristics of the state's 10 intersegmental student preparation programs in terms of their philosophy, approach to implementation, participating institutions, objectives, services, school and student demographics, and resources. Part 4 examines the extent to which the programs are achieving the objectives of educational equity, and part 5 presents four preliminary conclusions (e.g., evidence for program effectiveness and the strength of the intersegmental approach) and five recommendations (e.g., that information on program effectiveness should be reported at the project level). Appendixes, which make up the bulk of the document, reproduce the reports submitted by the 10 programs, namely: Alliance for Collaborative Change in Education in School Systems/The Cooperative College Preparatory Program; California Academic Partnership Program; California Student Opportunity and Access Program; College Admissions Test Preparation Program; College Readiness Program; Early Academic Outreach Program; Expanded Curriculum Consultant Project; Mathematics, Engineering, Science Achievement Program; Middle College; and University and College Opportunities Program.
