The easyCBM[R] assessment system is an online benchmark and progress monitoring assessment system designed for use within a response to intervention framework. Educators using easyCBM[R] are often interested in using the results to predict students' state test performance. In the following technical document, we report diagnostic efficiency statistics using a large sample from three districts across the state. The Oregon state test was the criterion in a Receiver Operator Characteristics curve analysis. In addition to diagnostic efficiency statistics, optimal cut scores are reported for predicting whether students will meet expectations on the Oregon state test. (Contains 12 tables.)
