The goal of this study has been to develop a more complete understanding of the total cost to deliver CERDEP under such varied circumstances as the provider type, local cost structure, teacher qualifications, and other aspects of program structure. Based on information on CERDEP costs gathered from ten illustrative providers throughout the state, we aimed to understand the cost components that providers face, both to support instruction and operate programs. Armed with this information, we have developed model-based estimates of the total per-pupil cost of CERDEP under alternative contexts such as public versus private providers, low- and high-cost locales, and such structural features as size of classroom group and the educational credentials of the lead teacher. These estimates have in turn supported an analysis of the ability of CERDEP reimbursements alone, or in combination with other public funds, to cover the costs CERDEP providers are estimated to incur.
