The purpose of this study was to determine what, if any, associations exist between students' academic success on achievement tests and the predictor variables of students' socioeconomic status, participation in an after-school program, and gender. Middlesboro Intermediate School contains a high number of students who participate in the federal free- or reduced-price school meals program, as well as attend the after-school program. This study factored in the student's academic success on the Kentucky Core Content Test and the socioeconomic status of students based on their qualification for the federal free- or reduced-cost school meals program, their participation in the after-school program, and their gender. This study was based on test results for students in the fourth grade in the areas of math, science, reading, writing on demand, and writing portfolio, as well as the test results for the fifth-grade students in the areas of arts and humanities, practical living-vocational studies, social studies, math, and reading. The entire school population was included except for students never attending the after-school program and students receiving testing modifications on the Kentucky Core Content Test. Based on the analysis of the data and findings of this study, the implementation of an after-school program appears to have benefits for all students regardless of socioeconomic status; however, student success differs by content areas and the number of days of attendance in the after-school program.
