POLICY BRIEF FOR THE EARLHAM COUNTY PUBLIC SCHOOL DISTRICT The Eаrlhаm Cоunty Public Schооl District is а very large and diverse school district that serves over 100,000 students. The District is interested in raising overall student literacy performance, but also in improving the equitable distribution of that achievement among students that have traditionally not been well served. The District has decided to focus on its Kindergarten classrooms, given the importance of early student experiences for later student success. More specifically, it has decided to focus on one classroom characteristic that is relatively easy to manipulate from an implementation standpoint—kindergarten class size. Although prior research suggests that children learn more in smaller kindergarten classes, the District is not convinced that such benefits are present in their community. Before spending millions of dollars reducing class sizes, they are interested in whether—even descriptively—smaller class sizes are associated with student outcomes, particularly literacy development. They are interested in potentially reducing all kindergarten classes in the District to fewer than 16 students. To address this question, you have been contracted by Earlham County to conduct a series of investigations that they hope will inform their decision of whether to implement the policy. You refer to the dataset as the Earlham County Longitudinal Study, Kindergarten Cohort (ECLS-K). Again, the District recognizes that any statements regarding the observed links between class sizes and student outcomes are descriptive/correlational rather than causal. But they view this as a first step to potentially conducting more robust analyses in the future. Assume that the readers of your report will be assisted by Earlham County’s assessment and evaluation staff, who are well versed in statistical reasoning and writing. In short, feel free to write for a technical and quantitatively sophisticated audience. These assessment specialists will “translate” your findings for district-level administrators. The brief should include the following main sections, and should address each of the sub-questions within each section. The full code is available at the bottom of the exam.
