The study reports achievement data over four school years (1978-82) from standardized tests administered to approximately one million students per year in the state of Indiana. The reports show the percent of students performing in each of three bands of stanines--1,2,3; 4,5,6; 7,8,9. Representative grades from primary, intermediate, junior/middle, and high school are included. Subject areas include reading, composition, spelling, social studies, mathematics, and science. All achievement score information comes from reports sent to the state educational agency by each local public school district, as well as each certified private school in Indiana. Overall, Indiana students performed significantly better than national norms in all areas assessed and showed some gains in the years that the state's educational improvement program has been in effect. Achievement shows up slightly better in primary and intermediate levels than at junior/middle and high school. Results in spelling do not show up quite as well as other areas assessed. In general, results contradict current national alarm over achievement in the nation's schools. (Author/PN)
