Anderson, Daniel; Park, Jasmine, Bitnara; Lai, Cheng-Fei; Alonzo, Julie; Tindal, Gerald – Behavioral Research and Teaching, 2012
This technical report is one in a series of five describing the reliability (test/retest/and alternate form) and G-Theory/D-Study research on the easy CBM reading measures, grades 1-5. Data were gathered in the spring 2011 from a convenience sample of students nested within classrooms at a medium-sized school district in the Pacific Northwest. Due…

Wray, Kraig; Lai, Cheng-Fei; Sáez, Leilani; Alonzo, Julie; Tindal, Gerald – Behavioral Research and Teaching, 2013
We report the results of an alternate form reliability and criterion validity study of kindergarten and grade 1 (N = 84-199) reading measures from the easyCBM© assessment system and Stanford Early School Achievement Test/Stanford Achievement Test, 10th edition (SESAT/SAT-­10) across 5 time points. The alternate form reliabilities ranged from…

Anderson, Daniel; Lai, Cheng-Fei; Nese, Joseph F. T.; Park, Bitnara Jasmine; Saez, Leilani; Jamgochian, Elisa; Alonzo, Julie; Tindal, Gerald – Behavioral Research and Teaching, 2010
In the following technical report, we present evidence of the technical adequacy of the easyCBM[R] math measures in grades K-2. In addition to reliability information, we present criterion-related validity evidence, both concurrent and predictive, and construct validity evidence. The results represent data gathered throughout the 2009/2010 school…

Lai, Cheng-Fei; Nese, Joseph F. T.; Jamgochian, Elisa M.; Alonzo, Julie; Tindal, Gerald – Behavioral Research and Teaching, 2010
In this technical report, we provide the results of a series of studies on the technical adequacy of the early reading measures available on the easyCBM[R] assessment system. The results from the two-level hierarchical linear growth model analyses suggest that the reliability of the slope estimates for the easyCBM[R] reading measures are strong,…
