A discussion of concurrent enrollment programs, in which high school students can enroll in college-level courses before graduation and simultaneously receive credit for their diplomas and receive college credit, shows how such programs can address concerns about high school-college articulation and describes several program models in action. Two aspects of articulation are addressed: high school-college curriculum redundancy and the changing demographics of the college population, affecting the appropriateness of many introductory college-level courses. Benefits seen in concurrent enrollment programs include acceleration of progress for students, reduced tuition costs, reassurance for parents concerning their children's ability to handle college-level academic responsibilities, relief of high school senior ennui, productive interaction between high schools and colleges, improved high school faculty status, enhanced high school standing, facilitated student recruitment, grant opportunities, school-college faculty interaction, enhanced college-community relations, and social equity. Programs at Syracuse University (New York), Florida International University, Kingsborough Community College (New York), LaGuardia Community College (New York), Seattle University (Washington), and the Minnesota and Florida statewide programs are described. Suggestions for designing, implementing, and evaluating a concurrent enrollment program are given. 19 references. (MSE)
