This report, produced by CES in 2015, documents the learning from implementation of the Student Universal Support Ireland (SUSI) in 2012. The report analyses implementation of the scheme through the lens of implementation science concepts, such as stages and enablers. It examines the challenges of quickly implementing major reforms in the context of significant financial and staffing constraints. The report will be of particular interest to policymakers and commissioners who are considering or planning new programmes or major reforms.
