IXL Math and IXL ELA meet ESSA Tier II
requirements for evidence-based interventions
IXL Math and IXL ELA meet the criteria for Tier II evidence-based interventions set by the U.S. Department of Education's Every Student Succeeds Act (ESSA).
In the 2019 study "The Impact of IXL Math and IXL ELA on Student Achievement in Grades Pre-K to 12," researchers found that students using IXL experienced greater growth on the NWEA MAP assessments than students without IXL. In addition, the effect of IXL was dose dependent: students who used the program more experienced even greater growth than their peers.
This rigorous evaluation featured a quasi-experimental design and included:Download the ESSA Research Report
- A large sample size of 4,000 students across multiple sites
- Students in all grade levels, pre-K to 12th grade
- Positive, statistically significant results for all NWEA MAP goal areas in math and reading
