This book provides over 300 summaries of joint-venture programs between secondary and postsecondary schools. The overall purpose of the partnership programs is to improve the chances for at-risk students to graduate from high school and have a successful college experience. The main portion of the book is divided into four parts, each focusing on a major grouping of partnerships: (1) "Programs and Services for Students"; (2) "Programs and Services for Educators"; (3) "Coordination, Development, and Assessment of Curriculum and Instruction"; and (4) "Programs To Mobilize, Direct, and Promote Sharing of Educational Resources." Each part begins with a brief introduction, followed by an array of abstracts that describe these partnership activities. Following these four parts is a comprehensive national directory to the programs in the national computer database. For each partnership program, the directory lists the following: name of the higher education institution; name of the partnership; name, address, and telephone number of the higher education contact person; and a five-digit program reference number. Appendices include a blank survey form for readers interested in submitting new entries to the database or updating existing information, and information for accessing the national partnership computer database at Syracuse University. Contains an index. (GLR)
