Validity Report for Lexia Reading Core5® with NWEA™ MAP®

Lexia Reading Core5 performance measures are shown to be valid indicators of reading ability based on comparisons with RIT scaled scores from the Northwest Evaluation Association Measures of Academic Progress (MAP).  Significant correlations are found between Core5 performance measures and MAP RIT scores at the beginning, middle, and end of the year.  In addition, On Target Predictor scores from Core5 can be used to predict proficiency on the MAP assessment.  These findings indicate that Core5 can serve not only as an instruction program but as a key component in a school's literacy assessment.
