In 2012, Altarum and Y-USA worked together to create a plan for evaluating compliance with the PHA commitment using the Framework for Program Evaluation developed by the Centers for Disease Control and Prevention Evaluation Working Group. The primary aims of the evaluation were to (a) assess the extent to which Y-USA was fulfilling its commitment to PHA, (b) describe the ways Y-USA and its partners supported efforts to improve HEPA in afterschool programs, (c) describe challenges and facilitators to implementing the standards and identify innovative best-practice solutions to common barriers, and (d) identify ways that Y-USA can better support local Ys in sustaining changes made to improve HEPA in afterschool programs.
