Learn about the importance of intermediaries in building Out-of-School Time (OST) systems in the first of a three-part webinar series on OST system building sponsored by The Wallace Foundation, in collaboration with the YEF Institute, the Collaborative for Building After School Systems (CBASS) and the Forum for Youth Investment. This webinar will feature findings from and reactions to the Collaborative for Building After-School Systems’ (CBASS) first national survey of OST intermediaries and will offer advice to cities on how to be most effective.
