In 2006, The David and Lucile Packard Foundation began to support the After School Education and Safety Program (ASES)–funded expansion of after-school programs in California. The Foundation invested in the establishment of technical assistance (TA), workforce development, and leadership infrastructure to help build a sustainable system that provides better programmatic and financial support for California’s after-school programs. This report examines the ways in which the Foundation’s investments from 2007 through 2010 have contributed to the continuous improvement of the after-school field.
