A randomized control trial study to examine the impacts of arts learning opportunities on educational outcomes with 2,430 students who were receiving special education services at the 42 schools participating in our Arts Access Initiative evaluation. Twenty-one of these 42 schools were randomly assigned to receive substantial increases in arts learning opportunities provided through schools’ partnerships with arts organizations. In this study, we aim to provide valuable contributions to the fields of arts and special education research through the first large-scale experimental investigation of arts educational impacts on special education students’ school engagement and learning outcomes.
