Youth in the juvenile justice system need access to high-quality educational services and supports in order to reduce their risk of reoffending and increase their likelihood of further participation in education and the workforce. However, states have historically struggled to provide effective educational services to youth who are incarcerated. Educational programs and schools in long-term juvenile justice facilities are rarely held accountable by the state for the provision of quality services and for ensuring that youth are improving their academic performance or gaining a credential similar to what they would earn at traditional public schools. Now, the new federal Every Student Succeeds Act (ESSA) provides states with an opportunity to intentionally focus on education for youth who are incarcerated by creating a structure that holds these programs and schools accountable. The goal of this policy brief is to provide state and local policymakers as well as education and juvenile justice leaders with information about how they can use requirements under ESSA to improve education and workforce outcomes for youth in long-term juvenile justice facilities. This brief: (1) summarizes relevant ESSA provisions and outline its key accountability requirements; (2) highlights three priorities for states to focus on as they contemplate accountability for juvenile justice programs and schools; (3) provides key questions to help state leaders consider their current policies and identify gaps and opportunities for improvement; and and (4) features states that are carrying out promising practices in each of the three priority areas, which can serve as examples for other states that are seeking to improve accountability for juvenile justice schools.
