Statewide results of South Carolina's Basic Skills Assessment Program (BSAP) are provided in terms of the percentages of students meeting statewide performance standards in reading, mathematics, writing, and science. BSAP tests were administered statewide on April 23-27, 1990, in grades 1, 2, 3, 6, and 8. The BSAP Exit Examination was administered to eligible students in grades 10, 11, and 12. In the 1989-90 academic year, 54,737 first-graders, 49,651 second-graders, 48,995 third-graders, 46,266 sixth-graders, and 43,552 eighth-graders were tested in reading and mathematics, for a total of 243,201 students. The 1990 BSAP test results indicate that a clear majority of students in grades 1, 2, 3, 6, and 8 met the standards on the BSAP reading, mathematics, and writing tests. Almost eight out of ten students in grades 1, 2, and 3, and almost six out of ten students in grades 6 and 8 met the standards on all tests administered. Gains of one percentage point or more in the past year were only noted in reading in grades 3 and 8; other scores remained relatively stable. Performance on the Exit Examination has improved each year for 10th-graders, with more first-time test takers passing. Spring 1990 marked the first administration of the BSAP science test to which state standards were applied. Percentages meeting the standard ranged from 46.0 in grade 8 to 57.5 in grade 3. Eleven bar graphs are presented. Seven appendices contain 86 pages of tables of results. Appendix H presents cautions in interpreting test results. (SLD)
