Schools Differ in Ability to Accommodate After-School External Programming
Adjusting the timing of program delivery to the school's preference may benefit schools that can accommodate in-school delivery. However, those schools that select after-school models may need additional support to introduce, build, and maintain an after-school culture. Although they are considered homologous units in cluster randomized trials, schools in the same geographic and demographic settings may still vary markedly in their ability to effectively participate in research and after-school activities.
