A growing number of schools and colleges are making college courses available to high school seniors. This document discusses factors affecting the success of partnerships between schools and colleges for the purpose of providing such courses and describes several programs currently operating. The author first identifies 10 basic principles underlying successful cooperation between schools and colleges. The report next discusses practical steps to take when starting a program. A list of questions serves as a checklist for administrators evaluating the quality of programs once they are started. The document concludes with descriptions of 10 programs from schools across the country. These descriptions note several characteristics of each program, including the nature of the community served, the extent of student participation, the type of relationship established among the institutions involved, the location where the students are taught, the effectiveness of the program, the means by which tuition costs are covered, the types of classes offered, and the transferability of the credit earned.
