Curriculum-based measurement (CBM) has conventionally included accuracy criteria with recommended fluency thresholds for instructional decision-making. Some scholars have argued for the use of accuracy to directly determine instructional need (e.g., Szadokierski et al., 2017). However, accuracy and fluency have not been directly examined to…

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…

In this technical report, data are presented on the practical utility, reliability, and validity of the easyCBM[R] mathematics (2009-2010 version) measures for students in grades 3-8 within four districts in two states. Analyses include: minimum acceptable within-year growth; minimum acceptable year-end benchmark performance; internal and…

Students learn at varying rates, and if a misconception in mathematics develops early, it may be carried from year to year and obstruct a student's progress. To identify fallacies in students' preconceived ideas, "Uncovering Student Thinking in Mathematics" offers educators a powerful diagnostic technique in the form of field-tested assessment…

Curriculum-based measurement (CBM) is a well established tool for formative assessment. CBM has also been used for prediction of state test scores. However, validity coefficients between math-CBM and state tests have been moderate at best (Skiba, Magnusson, Martson, and Erickson, 1986; Martson, 1989; Putnam, 1989). The purpose of the present…
