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…

Within a response to intervention (RTI) framework, students are administered multiple tests of equivalent difficulty. Changes in students' scores over time are then attributed to changes in learning. In the current study, we evaluated the reliability of score changes (i.e., slope) for the easyCBM[R] letter names, word reading fluency, and passage…

In this technical report, we present the results of a reliability study of the second-grade multiple choice reading comprehension measures available on the easyCBM learning system conducted in the spring of 2011. Analyses include split-half reliability, alternate form reliability, person and item reliability as derived from Rasch analysis,…

In this study, we describe two studies used to select appropriate assessments to measure phonemic awareness, alphabetic principle, and fluency in the Spanish language for students receiving literacy instruction in Spanish. We first describe two studies in which we use linear regression and correlations to examine the appropriateness of different…

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…

We present scaling outcomes for mathematics assessments used in the fall to screen students at risk of failing to learn the knowledge and skills described in the National Council of Teachers of Mathematics (NCTM) Focal Point Standards. At each grade level, the assessment consisted of a 48-item test with three 16-item sub-test sets aligned to the…

In this technical report, we provide reliability and validity evidence for the easyCBM[R] Reading measures for grade 2 (word and passage reading fluency and multiple choice reading comprehension). Evidence for reliability includes internal consistency and item invariance. Evidence for validity includes concurrent, predictive, and construct…
