Assessing students' emerging literacy skills is crucial for identifying areas where a child may be falling behind and can lead directly to an increased chance of reading success. The Waterford Assessment of Core Skills (WACS), a computerized adaptive test of early literacy for students in prekindergarten through 2nd grade, addresses this need.…

Two studies using similar methods in two states investigated the long-term predictive utility of two single-skill early numeracy Curriculum Based Measures (CBMs) and the degree to which they can adequately predict high-stakes test scores. Data were drawn from kindergarten and first-grade students. State standardized assessment data from the…

This report provides a description of the development process, field testing, and psychometric properties of a student mathematics test designed to assess grades 1 and 2 student abilities. The test was administered to 2,373 participating grade 1 and 2 students in 22 schools located in 2 public school districts in Florida during fall 2013. Focused…

This study focused on the predictive validity of fluency measures that comprise Dynamic Indicators of Basic Early Literacy Skills (DIBELS). Data were gathered from first through third graders attending 44 schools in 9 districts or local educational agencies that made up the first Reading First cohort in Michigan. Students were administered DIBELS…

This article describes efforts to examine the validity of a screening process that provides objective data for multidisciplinary team meetings where consideration is being given to teacher referral of a student for assessment and possible placement in special education. In this study, the accuracy with which this process, called Problem Validation…

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…
