Nearly all school districts in Nevada qualify for Chapter 1 funds for educationally and economically disadvantaged children. All Chapter 1 programs are evaluated annually, and children participating are given pre- and posttests to measure their gains during the school year. Program evaluation data for 1990-91 are summarized. The first section shows the average gains in normal curve equivalents for the state in reading, mathematics, and language, and the number of children served at each grade level. State average testing results are also shown. The second section shows a summary of gains made for the subjects each district serves, with a brief narrative about the Chapter 1 program for each of 15 districts. All districts are represented except for one that was ineligible and one that received an exemption from reporting because of different pre- and posttest instruments. Eight bar graphs and one table present the study totals, and there are four tables for each district. (SLD)
