Helping Students Meet Grade-Level Expectations and Close the Gap 


Lexia is research-proven to close the reading gap when used with fiedlity. During the 2015–2016 school year, Lexia examined the performance of more than 565,000 students students across the country who met their usage goals using Lexia Reading Core5®. Both on-target and at-risk students made significant gains that were not just limited to Lexia’s own instructional benchmarks—Success translated into improved performance in other common assessments such as STAR, MAPⓇ, DIBELS Next, and AIMSwebⓇ.

 

Among students who placed more than 2 years behind grade level in Core5 (defined as high-risk), 70% of those students who used the program as designed gained 2 grade levels of skills in 1 year. 

21% of students who began the year in grade-level materials completed their grade level in Core5 and advanced through the entire next grade level, gaining 2 years of skills in 1 year.
