In October of 2013 a decision was made to add a cost study component to the current Reading Partners? evaluation. The goal of this cost study is to assess the relative efficiency of the Reading Partners program in improving students reading scores compared to the other supplemental reading programs provided to the control condition in study schools. The cost analysis will provide a range of costs associated with the provision of Reading Partners and the alternative programs at 5 to 8 school sites that were included as part of the impact evaluation. Specifically the study will be designed and implemented to address the following research question: What is the cost of Reading Partners compared to the cost of the control condition at various sites that were included in the impact evaluation?
