This report summarizes the work of the Oregon Parenting Education Collaborative during its first five years, 2010-2015. OPEC is a multi-year initiative led by The Oregon Community Foundation, The Ford Family Foundation and Oregon State University. Financial supporters include The Oregon Community Foundation, The Ford Family Foundation, the Meyer Memorial Trust, The Collins Foundation, and OCF Donor Advised Funds. The initiative supports expanded access to best practice parenting education programs, with a focus on reaching parents of children prenatal to age six, and supports efforts to develop and strengthen regional parenting education "Hubs." OPEC is unique in its collaborative, foundation-led approach to building a statewide infrastructure for parenting education through community-based non-profits and public agencies. The OPEC initiative was launched in July 2010 with the funding of six regional parenting Hubs serving 12 counties, and nine Small Grant projects providing evidence-based classes and/or home visiting for specific groups of parents. As of fall 2015, 15 Hubs reach 26 Oregon counties and Siskiyou County, Calif., and OPEC has provided Small Grant funding to 17 additional Oregon organizations. OPEC has achieved strong outcomes in the building of regional infrastructure and parenting education partnerships, as well as increasing positive parenting capacities.
