The purpose of the pilot study was to assess the applicability and fit of the SAYO Evaluation System tools in ELT settings. ELT in this context refers to schools offering substantially longer school days than is required by the state. The intention of the study was to help inform upcoming evaluation work with the 21st CCLC grantees that were competitively awarded grants for use during an extended school day (as opposed to the historical out-of-school time use only), based on recent flexibility granted from the United States Department of Education. This report summarizes the findings from the study. (author abstract)
