Lexia is research-proven to close the literacy gap when used with fidelity
Approximately 898,000 students in grades K–5 used Lexia® Core5® Reading (Core5) with fidelity during the 2018–19 school year across the United States. Students of all abilities made substantial progress in Core5:

53% of students who started Core5 working on skills 2 or more grades below their grade level substantially reduced their risk for reading failure, ending the school year working on Core5 skills in their grade level or having reached their EOY, grade-level benchmark in Core5.
86% of students who started Core5 working on skills in their grade level reached their end-of-year, grade-level benchmark or beyond in Core5.
