Abstract
An increasing number of university-K-12 partnerships are addressing the out-of-school challenges that can often constitute barriers to learning for students. This chapter describes the role that universities have played in shaping models of schooling that are intentionally designed to support the whole child and integrate services and enrichment opportunities to support students. It outlines how this university-K-12 collaboration has occurred in three major phases in which universities have: 1) helped to develop and/or implement new approaches on the ground, 2) refine these approaches utilizing developmental science and best practice, and 3) deepened the measurement of the effectiveness and efficiency of the models, as well as strengthening their scalability and sustainability.
