|The purpose of this study was to investigate the correlation between performance on the DIBELS ORF Benchmark 2, the Terra Nova, 2nd Ed., and reading proficiency on the Ohio Grade 3 Reading Achievement Test. The research question examined the wisdom of using both the DIBELS ORF Benchmark 2 Indicator and the Terra Nova, as predictors for the Ohio Grade 3 Reading Achievement Test. After gathering archival data for the 136 students involved, a Pearson-Product Moment Correlation was used to determine this correlation. Data was additionally analyzed using a Hits and Misses Table. Results produced a significant, positive correlation between DIBELS ORF scores, the Terra Nova, and the Ohio Third Grade Reading Achievement Test. This study demonstrates, however, administering the Terra Nova as an additional assessment from March through May provides marginal student benefit. This study identifies the effectiveness of using early identification to predict reading mastery on high-stakes reading tests.
