One of the greatest challenges supervisors face is developing and retaining their staff. Site supervisors are in a continuous struggle to develop and train new employees on the fundamental skills--managing groups, dealing with disruptive behavior, and so on--that youth workers need before they can successfully implement learning activities. One way to break this cycle of continual on-boarding is to support site supervisors in implementing processes to build a high-performance culture in their afterschool programs. The intention is to build a culture in which staff collaborate and learn together to reach program goals. This essay recommends a model, borrowed from the corporate sector, for building a high-performance culture in afterschool programs at the site level. If implemented with fidelity, this model can support afterschool programs in stabilizing their workforce, improving their performance, and delivering quality services to children and youth.
