For almost a decade, 21st Century Community Learning Centers (21st CCLC) operating across the state of New Jersey have provided students in high-poverty communities the opportunity to participate in academic enrichment programs and other youth development and support activities. These activities, varying extensively in character from one program to the next, are generally designed to enhance the academic well-being of participating youth. The primary purpose of this report is to highlight how well 21st CCLC afterschool programs across New Jersey funded have fared relative to the goals and objectives specified for the program by the New Jersey Department of Education (NJDOE). The information contained in this report is the result of data collected and analyzed as part of a statewide evaluation of the 21st CCLC program in New Jersey, conducted by American Institutes for Research (AIR). The majority of the results outlined in this report are associated with 21st CCLC-funded activities and services delivered during the course of the 2013-14 school year. In particular, this report seeks to explore how academic and school-related outcomes of students who participated in the 21st CCLC program compare with the results of similar students not participating in the programs. For instance, do students attending 21st CCLC programming have better outcomes in terms of reading or mathematics assessment scores, truancy rates, or retention? Additionally, the report investigates whether any observed effects are greater at higher levels of attendance. This report also outlines how well New Jersey 21st CCLC grantees performed in relation to a set of leading indicators. These indicators are meant to assess how well grantees are implementing programming theorized to support the achievement of goals and objectives specified by NJDOE for the 21st CCLC program. It is intended that this information will provide additional guidance and insight to NJDOE and grantees currently providing programming about the steps they should take to further support and undertake meaningful program improvement efforts.
