The purpose of this study was to examine the concurrent validity of the assessment for an early language and literacy project. The goal of the project was to promote a successful transition to kindergarten for preschoolers who were at risk for reading difficulties by equipping them with the necessary language and literacy skills needed for early reading success. Both child outcome data and classroom/teacher level data were collected at the beginning and the end of the academic semester. Child-level pre- and post-tests indicated that participating children's language and literacy skills were improved in name writing, letter recognition, beginning sound awareness, rhyming awareness, and print knowledge. Findings from the validity study suggested a significant relationship between- and within-child outcome measures. A significant relationship was also found between norm-referenced child outcome measures and classroom-level measures; however, no significant relationship was identified between criterion-referenced child outcome measures and classroom-level measures. Implications of this study were discussed. (Contains 5 tables.)
