The purpose of this study was to determine if the Summit Learning Platform, a type of Intelligent Tutoring System, has a positive association with mathematics achievement of high school students in grades nine through eleven. The study was conducted in a Midwest suburban school district among three high schools within the same district. Further, a quasi-experimental research design was used with a sample size of 2000 students in the control group and 450 students in the treatment group. Data were compiled from the 2018-2019 school year and applied a combination of t-tests and analysis of variance (ANOVA) to compare the mean scores of the two groups. As comparison points, the Northwest Evaluation Association (NWEA), pre-ACT, and ACT were used in this Midwest district as measures among all students. The results demonstrated that students using the Summit Learning Platform showed significant gains when using their pre-test and post-test scores, but there was not statistical significance when analyzing the measures between the control and treatment groups. As more school districts utilize technological tools in far-reaching efforts to raise achievement levels in math, the intent of the study was to demonstrate potential benefits of the Summit Learning Platform for districts across the nation.
