With support from The Wallace Foundation, the American Youth Policy Forum (AYPF) has been coordinating a number of learning experiences for cities aimed at increasing opportunities to share best practices and providing access to best practices and national trends. Initially, 57 cities convened in Baltimore, Maryland in February 2013 for the "Better Together: Building Local Systems to Improve Afterschool" conference. In the 18 months following the conference, AYPF with assistance from a number of other national organizations, has provided additional information and support to the cities as they work to build and strengthen their afterschool systems. To aid communities in locating available national resources, AYPF has compiled this directory to share an understanding of the range and type of resources available to assist local afterschool system building. In collaboration with a number of partners, AYPF sought input on organizations within the afterschool and youth development sector that would have relevant and valuable resources for communities looking to build afterschool systems. The following criteria were used for inclusion. Organizations must: (1) Serve a national audience; (2) Provide free resources or tools to local afterschool system builders that either support system-building work or advance understanding of the value of a coordinated approach; and (3) Offer resources or tools that fall within one of AYPF's predetermined categories (Research--Case Studies, Research--Facts and Figures, Research--Evaluations; Advocacy--Federal, Advocacy--State, Advocacy--Local, Technical Assistance and Tools--Practice Tools, Technical Assistance and Tools--Policy Briefs, Technical Assistance and Tools--Direct Technical Assistance, Convenings--National, Convenings--Regional/State/Local). This directory includes: (1) A comprehensive listing of over 50 organizations; (2) Resources categorized by key themes; and (3) Easy access to relevant information, data and briefs.
