This report presents the findings of the first full year of the implementation of the Power of Discovery: STEM2 Initiative that occurred during the 2013-14 academic year. The Power of Discovery (PoD) Initiative is guided by a logic model in which systemic support of afterschool STEM programming (the "treatment") is posited to facilitate improvements in staff beliefs about STEM, and program activities, which are posited to then support gains in STEM-related student outcomes. During 2013-14, a research team from the University of California, Irvine (UCI) collected systematic data to test this logic model. (author abstract)
