31 statewide efficacy studies covering more than 64,437 schools show that IXL works. These research-backed best practices can help your district to optimize learning and experience the IXL EffectTM in your schools.
Just 15 IXL questions per week impacts student success
Our research has shown that schools where students answer at least 15 questions per week outperform all the others.
Strive for mastery
Take the IXL EffectTM to the next level by striving for mastery
IXL is designed to support students toward authentic skill mastery, and research shows this approach works. When students consistently reach proficiency and mastery of IXL skills, schools see as much as a 16-point bump on state assessments.
Experience IXL for Math and ELA
Enhance learning in both math and ELA with IXL
Research shows that schools achieve even greater performance gains when they support student learning with both IXL Math and IXL ELA.
Use IXL across all grade levels
Implement IXL consistently across all grades
Schools that use IXL across all grade levels see greater growth on state assessments.
Grow more every year with IXL
The longer you use IXL, the greater the IXL EffectTM
IXL schools are outperforming the others, and the longer they use IXL, the better they do. Research shows that school performance continues to improve after using IXL for 2 and 3 years.
