In this technical report, data are presented on the predictive and concurrent relation between various student demographic variables (gender, race/ethnicity, special education status, Title 1 status, English language learning status, and economic disadvantage) and three reading easyCBMs (passage reading fluency, vocabulary, and multiple-choice comprehension) with a criterion measure of the Oregon Assessment of Knowledge and Skills (OAKS). The findings are replicated for two school districts and across three time periods. Consistently, a significant amount of the variance for the criterion measure is explained by the combination of variables, particularly from the three reading measures.
