 District-designated staff in all three states will be trained and certified to deliver the NISL program to future cohorts, ensuring sustainability and scalability beyond the life of the grant.In addition to the wide-scale impact of the support provided by the grant, the initiative will also produce a “gold standard” study of NISL's EDP and coaching.This study, conducted by a team of external evaluators from the RAND Corporation, will use a rigorous randomized control trial design.
