This study examines selected variables as they relate to the performance of sixth-grade learning disabled (LD) and behaviorally-emotionally handicapped (BEH) students on minimum competency tests administered by the North Carolina public schools. The sample consisted of 313 LD and 79 BEH subjects who attended the 1988 Basic Education Program Summer School in 38 selected school districts. Data were collected describing the independent variables including students’ race, sex, handicapping condition, parent education level, and school and teacher characteristics including instructional time, class size, teacher training, and teacher certification. The dependent variables for the study included language, reading, and mathematics performance scores on the Minimum Skills Diagnostic Tests (MSDT). Data were analyzed by utilizing a multiple regression model to describe the relationships between selected demographic and school variables and language, math, and reading gain scores on the MSDT and by utilizing dependent t tests for differences between the means for pre- and post-test performances. Although gains were made by LD and BEH students on the MSDT, it was concluded that the student and school variables used in the study were not predictive of achievement. / Ed. D.
