Helping Students Meet Grade-Level Expectations and Close the Gap 
Lexia is research-proven to close the literacy gap when used with fidelity



Over 712,000 students in grades K–5 used Lexia Reading Core5® with fidelity during the 2016–2017 school year across the United States. Students of all abilities made substantial progress in Core5: 
 

  • The vast majority of students (87%) who started Core5 working on skills in their grade level reached their end-of-year, grade-level benchmark or advanced to complete the next grade’s end-of-year benchmark in Core5.
     
  • More than half of students (52%) who started Core5 working on skills one grade below their grade level closed the reading gap and reached their end-of-year, grade-level benchmark in Core5.
     
  • Over half of students (53%) who started Core5 working on skills two or more grades below their grade level substantially reduced their risk for reading failure, ending the school year working on skills in their grade level or reached their end-of-year, grade-level benchmark in Core5.
