Drawing from on-site assessments of the implementation and effectiveness of 21 selected Extended Opportunity Programs and Services (EOPS) programs operating at California community colleges, this report summarizes information collected between September 1986 and April 1987 through student and faculty/staff surveys, and 799 detailed interviews with faculty/staff and 242 interviews with students. An executive summary describes the types of services typically provided by EOPS programs in the areas of management, outreach and recruitment, instructional development and services, counseling, transition to four-year colleges, special activities, financial aid, and staff development and training. Chapter 1 describes the Operational Program Review (OPR) process used to examine the 21 programs, identifies primary information sources, and offers a profile of EOPS students. Chapter 2 presents a general survey of the structured, planned services the OPR teams found in the programs reviewed in 1986-87. Finally, chapter 3 offers a summary of 1986-87 OPR recommendations for the improvement of EOPS, covering the areas of program administration, deficiencies in program plans, compliance with Title 5, outreach and recruitment, instructional development, counseling, transition to four-year colleges, special activities, financial aid, and staff development. Specific recommendations are presented for each program reviewed. Appendixes present an abbreviated handbook of OPR procedures, including the survey instruments. (LAL)
