Lexia® Core5® Reading and Lexia® RAPID™ Assessment

Correlations: Students’ EOY Core5 Level correlated significantly with their EOY RSP scores in RAPID (p<0.01). Correlations in each grade fell within the medium range (.4 - .6), which is considered strong when evaluating a reading assessment (or program).

Alignments: Students who ended the year working on materials above their grade level have reached benchmark, while those who ended the year working on materials in or below their grade level have not reached benchmark. Of the 5987 students who reached benchmark, 82.4% had a Moderate/High RSP score on RAPID. In contrast, 50.6% of students working on grade-level material had a Moderate/High RSP score, and only 15.6% of students working below grade level had a Moderate/High RSP score. This indicates a close alignment between Benchmark Status in Core5 and performance on RAPID.
