The purpose of this Mississippi study was to determine if there was a correlation significantly different from zero between test scores, level of accreditation (Level 1--the 17 highest-scoring public school districts in the study, or Level 2--the 18 lowest-scoring), district expenditure per pupil, district size, and eligibility of students for free/reduced lunches as measured by the Basic Skills Assessment (BSAP), the Functional Literacy Examination (FLE), and the Stanford Achievement Test (SAT). All three tests measured reading and math. The BSAP and the FLE measured written communication. The SAT measured language. The BSAP was administered in grades 3, 5, and 8; the FLE was administered in grade 11; and the SAT was administered in grades 4 and 6. Overall, the results showed that the best predictor for reading was reading, the best predictor for math was math, and the best predictor for written communication or language was written communication or previous language test scores. However, the second best predictor for the Functional Literacy Examination scores was the eligibility of the student for free/reduced lunches in the district. There are 12 tables and a list of 13 references. (LMI)
