Abstract

Despite current legislation, students continue to struggle with attainment of statewide academic standards as measured by high-stakes assessment. The purpose of the current study was to examine the relationship between DIBELS ORF, AIMSweb Maze-CBM, and the North Carolina End-of Grade (EOG) Assessment of Reading Comprehension. The study investigated the diagnostic accuracy of established cutoff scores and determined optimal cutoff scores. Participants included 336 students in third, fourth, and fifth grades. Results of the study indicated a significant relationship between the measures. Receiver Operating Characteristic (ROC) Curves revealed statistically significant Area Under the Curve (AUC) values for ORF and Maze. Optimal cutoff scores to maximize sensitivity and specificity yielded slightly different cutoff points for ORF and Maze.
