This technical report is one in a series of five describing the reliability (test/retest an alternate form) and G-Theory/D-Study on the easyCBM reading measures, grades 1-5. Data were gathered in the spring of 2011 from the convenience sample of students nested within classrooms at a medium-sized school district in the Pacific Northwest. Due to the length of the results, we present results of each grade level's analysis in its own technical report, sharing a common abstract, introduction, and methods section, while differing in the results and conclusions. Test form administration order is appended. (Contains 8 tables.)
