National Middle School Lexile Study

Middle school students believe — and achieve nearly 2X expected Lexile gains.

When researchers looked into the test scores of nearly 87,000 middle schoolers across the nation, they found that those who had the opportunity to take advantage of Achieve3000's TeenBiz nearly doubled their expected growth norms after only one year. The same level of achievement also was seen for students who had been struggling readers. This group began with reading levels at least two years below average, yet made a remarkable average Lexile gain of 118 points.

English Language Learners (ELLs) and Special Education students who had access to TeenBiz also showed that they could close the achievement gap after only one year. On average, ELLs more than doubled their expected Lexile growth, while Special Education students saw a gain of more than 1.5 times the expected.
