Lexia® Core5® Reading Supports Reading Growth for 3 School Years
PURPOSE: The aim of this study was to assess the impact of using Lexia® Core5® Reading during multiple school years on students’ reading performance. In addition, the study asked whether use of Core5 during multiple school years could help mitigate the effects of summer slide.
METHOD: This longitudinal study tracked the reading performance of students using Core5 throughout three school years. The same group of students used Core5 during kindergarten, first, and second grades and assessment data were gathered in fall and spring of each school year using the Group Reading Assessment and Diagnostic Evaluation (GRADE).
KEY FINDINGS
- During each school year—kindergarten, first, and second grades—students made significant gains on the GRADE.
- Students’ performance on the GRADE declined from spring of one school year to fall of the next, indicative of summer slide.
- Students’ performance on the GRADE showed significant improvement from fall of one year to fall of the next, pointing to the benefits of using Core5 to help overcome summer slide.
- Of the students who started kindergarten scoring below average on the GRADE, 91% finished second grade scoring in the average range or above.
