This issue of "New Directions for Community Colleges" presents practical models and new strategies for creating powerful programs in concurrent enrollment, a rising trend in providing educational opportunities for college coursework to students in high school. The contributors draw from strong statistical data and demonstrate the effectiveness of seamless education with models of successful collaboration in existing programs, including the Virginia Plan for Dual Enrollment; the Salt Lake Community College model of curriculum design, faculty development and student success; Ohio's Postsecondary Enrollment Options program; Miami's nationally acclaimed New World School of the Arts; and Columbus State Community College Model for Successful Implementation. Incorporating a comprehensive overview with detailed account of positive legislative actions, as well as a valuable sampling of literature in the field, the contributors also explore the core tenets of collaborative education - the view that such education is a continuum; that program course offerings complement the high school curriculum rather than supplant it; and that accessibility, financial support, and academic support services for dual enrollees is crucial. In step-by-step approaches to creating valuable programs, the authors detail all the components necessary for the success and credibility of concurrent enrollment with a focus on the faculty liaisons from appropriate disciplines - along with active involvement of community college department chairpersons, academic deans and chief instructional officers - that provides the framework for an ever-improving concurrent enrollment program. This is the 113th issue of the quarterly journal "New Directions for Community Colleges."
