Background. Research studies have examined CBMs as predictors of standardized test performance; however, no studies have examined the possible predictive relationship between CBMs and the MAP test with a diverse population in the state of Nebraska. Purpose. This study measures the efficacy of using curriculum-based measurements, oral reading fluency and maze, as predictors of performance on the Measures of Academic Progress (MAP) in the state of Nebraska. Methods and Results. Archival data were collected from a public elementary school in Nebraska, which enrolls diverse students from many cultural backgrounds. The participants of this study were 376 elementary students in 2nd through 5th grade. The participants took the CBM oral reading fluency, maze, and MAP reading assessments in the Spring and Fall Semesters of the year 2009. The findings of this study indicated that the oral reading fluency and the combination of oral reading fluency and maze scores significantly predicted MAP reading scores (p < .05) in both semesters. Conclusions. The evidence obtained in the present study suggests the idea of using oral reading fluency to monitor students’ progress and to use it to target students who are at-risk of failing high-stakes reading tests.
