This case study investigated the phenomenon of the black white test score gap by seeking to determine if there was a difference in the academic performance of African American students and their White peers. The determination of student academic performance was made using scores from second semester Algebra II classes at two high schools in the Tucson Unified School District. The data covered three academic years and was analyzed via SPSS (independent samples t-test, ANOVA, and a pairwise analysis) and content analysis for qualitative analysis. Findings revealed that there was no variance in the scores of African Americans and their White peers attending an affluent school; however African Americans attending a low-income school scored lower than all groups that were compared in this study.
