The purpose of the current study was to determine the relationship between the PEAK Relational Training System Assessments and the Kaufman Test of Educational Achievement, Third Edition long form in children with autism and other cognitive or language delays. 29 participants were administered the PEAK Relational Training System Battery of Assessments and the Kaufman Test of Educational Achievement. This study sought to extend previous literature examining the validity of PEAK Assessments as compared to previously validated assessments as well as add to the body of literature examining the relationship between academic achievement and language and cognition development. Understanding the interaction between verbal behavior skills, derived relational responding, and academic skills may enable clinicians and educators to serve their learners in a more effective, comprehensive way. The results of this study suggest there is a moderately strong, statistically significant relationship between the PEAK assessments and the Kaufman Test of Educational Achievement Academic Skills Battery Composite (r=0.6675, p<0.0001, R2=.4455) and a strong, statistically significant relationship with the Kaufman Brief Achievement Composite (r=0.7974, p<0.0001, R2=.5611).

Accountability for student learning outcomes is of importance to parents and school and district administrators, especially since the passage of The No Child Left Behind Act in 2001. The requirement for high-stakes testing to measure progress has fostered interest in ways to monitor student preparedness during the school year. This study used 2014 and 2015 test data from of 154 students from one elementary school to measure the correlation between individually administered Kaufman Test of Educational Achievement Brief Reading and DIBELS Next reading assessments and outcomes on the high-stakes Utah SAGE test. This correlational study used Pearson correlation coefficients to determine redundancy across the tests, and used multiple regression to assess how well scores on the KTEA and DIBELS Next tests predict students' subsequent scores on the SAGE test. Results indicate that DIBELS Next was a strong predictor of SAGE outcomes while KTEA Brief results were moderate predictors.
