Abstract: The California Department of Corrections and Rehabilitation, a large system with 35 adult prisons, is in the second year of expanding horizons by implementing a large reform effort to base both academic and career technical instruction on evidence-based practices. An important piece of the project is the implementation of a professional learning community at each institution. Professional learning communities have been adopted widely in K12 and more and more in adult education. The corrections environment offers some specific but not insurmountable challenges. Attend this session to hear about the challenges, the successes, and the lessons learned so far.
