The "General Report" and "Executive Summary" provide information about the performance of the public school system of Utah. The Utah Statewide Educational Assessment (USEA) Program began in 1975 and has continued every 3 years through the April 1990 assessment, to be replaced in fall 1990 by a new testing program. The new program will test all students at grades 5, 8, and 11. The USEA provides information in the following areas: (1) achievement by Utah students; (2) how demographic factors influence achievement; and (3) instructional practices that result in high student achievement. The "General Report" presents the procedures and results of the sixth USEA in 1990. The "Executive Summary" summarizes the procedures and results of the sixth USEA and highlights changes and recommendations for change. Both volumes provide data on student outcomes, school classifications and student demographic characteristics, and perceptions of educational processes. The 1990 USEA tested over 5,000 fifth graders in 65 elementary schools and over 2,500 11th graders in 32 high schools. At the fifth-grade level there were five significant positive changes since 1987 and two areas of decline (language expression and academic learning time). For grade 11, four areas showed significant gains, and none declined. The "General Report" contains 38 exhibits, primarily student scores, a list of 17 references, and 1 appendix of 1990 data. The "Executive Summary" lists 12 references and contains 9 exhibits. (SLD)
