This report documents,in detail, student achievement in Emergency School Aid Act (ESAA) programs. Its purpose is to provide reference or baseline data for ESAA and other compensatory program administrators and researchers working with disadvantaged students. The data tables and figures can be used to answer the following types of questions: (1) How does the achievement score distribution of students in some programs of interest compare with the achievement level of disadvantaged students in a reference sample (ESAA sample)? (2) Have the within-year achievement gains of a given set of students met the gain expectation derived from ESAA students of similar initial ability? and (3) Over a two or three year time span, have the students made gains meeting the expectation provided by a reference sample of ESAA students. The ESAA evaluation was conducted on a sample of schools receiving ESAA funds. For each ESAA school, a control school from the same district which received no ESAA funds but was otherwise comparable to the ESAA funded school was also selected. Within each school, three grades were selected to be analyzed. These were the 3rd, 4th, and 5th, grades at the elementary level, and the 10th, 11th, and 12th grades at the secondary level. The schools from which the students were sampled had a large percentage of disadvantaged students, a large percentage of minority enrollment, and low reading and mathematics achievement test scores.
