As a result of the Educational Reform Act in 1982, the Mississippi State Board of Education adopted accreditation levels from 1 to 5, with 1 being the lowest level. In 1988, 17 school districts were assigned to the Level 1 status by the Commission on School Accreditation, based on results of the following performance standards: Basic Skills Assessment Program (BSAP), Stanford Achievement Test (SAT) in grades 4 and 6, and Functional Literacy Examination (FLE) in grade 11. As mandated, all Level 1 school districts must write and implement a district remediation plan. The MSDE employed 57 consultants to work with the 17 Level 1 school districts for 1 year. Each district's remediation plan was developed using the consultants' findings, the test data of the district, and other information about the areas of deficiency. This study assessed whether or not there were any differences in achievement between the 17 Level 1 school districts and the bottom 18 Level 2 school districts before and after a remediation process by the Mississippi State Department of Education (MSDE). The results in reading, math, and written communication on the BSAP in grades 3, 5, and 8; and on the FLE in grade 11 are reported. The SAT results in grades 4 and 6 in reading, math, and language are reported. Data for the 1987 and 1988 test administrations were obtained from the MSDE. The data were analyzed using an independent "t" test. The results show a significant difference in the 1987 testing of the Level 1 and Level 2 school districts. Before the remediation process, there was a significant difference in 6 of the 18 performance standards. These differences were found on the SAT for grades 4 and 6 in reading, math, and language. After the remediation process, only one difference was found in the 18 performance standards; this difference was on the SAT for grade 6 in language. Two data tables are included. (RLC)
