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 easyCBM reading measures, grades 1-5. Data were gathered in the spring of 2011 from a convenience sample of students nested within classrooms at a medium-sized school district in the Pacific Northwest.…

We examined instructional processes in classrooms where students with and without disabilities received mathematics instruction to understand the relationship among key instructional process variables and achievement as measured by interim and end-of-year summative assessments. Teachers (N = 78) completed instructional logs daily and administered…

Students with significant cognitive disabilities are eligible to participate in two statewide testing options for accountability: alternate assessments or general assessments with appropriate accommodations. Participation guidelines are generally quite vague, leading to students "switching" test participation between years. In this…

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…

We examined the relationship among key instructional process variables and the achievement of students with and without disabilities as measured by both interim and end-of-year summative assessments. Examination of the instructional process data indicated that students with and without disabilities receiving mathematics instruction in the same…

Much of the research on curriculum-based measurement (CBM) in reading has focused on oral reading fluency (ORF). However, ORF is only one of five critical reading skill areas in the wider construct of reading that includes foundational skills such as phonological awareness and phonics. In this research brief, we address the construct of readiness…

Identifying proper measure to monitor students' growth and understanding characteristics of growth patterns between different achieving groups are critical issues in terms of screening students at risk. To deal with this, we explored relationships of slopes and intercepts between word identification (ID) and passage reading fluency (reading aloud)…

Within a response to intervention system of teaching and learning, important instructional decision-making (e.g., implementation of targeted intervention) is regularly tied to the results of formative assessments administered to students throughout the academic year. The validity of these instructional decisions depends to an extent on the…

Since the easyCBM© learning system was first published in 2006, over $8 million of federal funding (both from the Office of Special Education Programs and more recently from the Institute of Education Sciences) has been used to develop, study, and refine the assessments available on the system. This Technical Manual summarizes the ongoing research…

In this technical report, we describe a study examining the internal structures of the easyCBM reading measures, Grades K-5. Data were gathered from a convenience sample of 114 Kindergarten students, 43 first graders, 82 second graders, 100 third graders, 109 fourth graders, and 71 fifth graders attending schools in Oregon, Georgia, South…

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 technical report, we document the development and piloting of easyCBM reading measures aligned to the Common Core State Standards, designed for use in screening students at risk for reading difficulty and monitoring their progress as they develop reading skills. The measures, which assess students' ability to respond to…

This study examined the type of growth model that best fit within-year growth in oral reading fluency and between-student differences in growth. Participants were 2,465 students in grades 3-5. Hierarchical linear modeling (HLM) analyses modeled curriculum-based measurement (CBM) oral reading fluency benchmark measures in fall, winter, and spring…
