Abstract: | In this study, we examined the reliability and validity of curriculum‐based measures (CBM) in reading for indexing the performance of secondary‐school students. Participants were 236 eighth‐grade students (134 females and 102 males) in the classrooms of 17 English teachers. Students completed 1‐, 2‐, and 3‐minute reading aloud and 2‐, 3‐, and 4‐minute maze selection tasks. The relation between performance on the CBMs and the state reading test were examined. Results revealed that both reading aloud and maze selection were reliable and valid predictors of performance on the state standards tests, with validity coefficients above .70. An exploratory follow‐up study was conducted in which the growth curves produced by the reading‐aloud and maze‐selection measures were compared for a subset of 31 students from the original study. For these 31 students, maze selection reflected change over time whereas reading aloud did not. This pattern of results was found for both lower‐ and higher‐performing students. Results suggest that it is important to consider both performance and progress when examining the technical adequacy of CBMs. Implications for the use of measures with secondary‐level students for progress monitoring are discussed. |
