Behavioral Research and Teaching
This technical report documents findings from a study of the internal consistency and split-half reliability of the easyCBM© CCSS Reading measures, grades 3-8. Data, drawn from an extant data set gathered in school year 2013-2014, include scores from over 150,000 students' fall and winter benchmark assessments. Findings suggest that the easyCBM© CCSS Reading measures are internally consistent, with a median Cronbach's alpha of 0.87, and a median split-half reliability of 0.76 (first half) and 0.82 (second half) across all 12 measures analyzed.
