The purpose of this quantitative study was to investigate the effects of adaptive computer-assisted instruction (CAI) on student mathematics achievement. The researcher sought to describe factors that may influence academic achievement for eight-grade students. The instruments used to gather data were post curriculum-based mathematics benchmark assessment data administered during fall, winter, and spring semesters, the spring mathematic assessment for the Georgia Milestones, and open and close-ended questionnaires. A purposeful sampling of 63 students were chosen to complete questionnaires. Data analyzed from the 2018 Mathematics scores from SchoolCity and the Georgia Milestones revealed that the SuccessMaker® online adaptive software tool positively impacted student mathematics achievement. The questionnaire responses showed that 100% of the teachers believed the online tutoring software to effective in improving student mathematics skills. Only 50% of the student participants rated the program as effective. Additionally, the students who received teacher and parental support with using SuccessMaker® obtained higher scores on the standardized assessment, Georgia Milestones.
