IXL ESSA Research
ESSA Tier 1 research shows that IXL leads to improved student outcomes.
IXL meets the criteria for Tier 1 evidence-based interventions set by the U.S. Department of Education's Every Student Succeeds Act (ESSA).
An independent evaluation of IXL Math's impact meets the required rigor of Every Student Succeeds Act (ESSA) Tier 1 and What Works Clearinghouse (WWC) standards for evidence-based interventions.
Johns Hopkins University conducted a randomized control trial to evaluate IXL Math's efficacy. The research revealed the following key findings:
- Students in IXL classrooms surpassed their control group peers: IXL Math students significantly outperformed the control group by an average of 10 points on the Star Math assessment.
- Underserved students achieved larger gains: Improved math performance was particularly pronounced among Hispanic, Special Education, English Language Learner, and FARMS (Free and Reduced Meal Program) student populations, with gains ranging from 13 to 17 points.
- A positive correlation between usage and achievement: IXL Math usage was significantly correlated with student performance on the Star Math and state assessments.
- Teachers overwhelmingly praised their IXL implementation: Approximately 90% of teachers reported that their implementation of IXL was successful and had a meaningful impact on instruction.
