This research report investigates the effect of IXL's Diagnostic Snapshot on student learning and achievement for grades 3 through 8. The study utilizes assessment data from four states: New York, Tennessee, Oklahoma, and Wisconsin, comparing the math achievement of cohorts that completed at least one Snapshot during the 2021-22 school year to those that did not. The findings indicate that students who completed the Diagnostic Snapshot demonstrated improved performance on state math assessments, with a proficiency rate approximately three percentage points higher than their non-Snapshot counterparts. The report outlines the methodology used, including a quasi-experimental pretest-posttest control group design and propensity score matching to ensure comparability between groups. It also details the structure of IXL's assessment suite, which includes Real-Time and Snapshot modes, and emphasizes the importance of personalized action plans generated for students post-assessment. The study aims to provide insights into the effectiveness of the Diagnostic Snapshot as a tool for enhancing student achievement.
