During the 2021-22 school year, 73% of schools in the Clark County School District (CCSD) qualified for federal dollars under Title I program criteria. Expectedly, CCSD receives the bulk of Nevada’s Title I dollars, which are largely expended on hiring additional teachers for the express purpose of class size reduction. In this report, CREA presents the results of our evaluation of the impact of Title I class size reduction on student outcomes and the processes by which those dollars were used by school leaders to reduce class sizes.
