In this article, the beta-binomial model for count data is proposed and demonstrated in terms of its application in the context of oral reading fluency (ORF) assessment, where the number of words read correctly (WRC) is of interest. Existing studies adopted the binomial model for count data in similar assessment scenarios. The beta-binomial model,…

Given the shift toward technology-based approaches to assessment and intervention and the growing popularity of virtual service delivery, practitioners must have data to inform whether student performance on curriculum-based measures (CBMs) is equivalent when administering assessments through different modalities. Reading CBMs are a widely used…

This technical report describes the development of oral reading fluency passages for use in the CBMSkills assessment system. Seventeen passages were created for each of Grades 1 through 5. Passages were designed to target the fluency component of a developmental model of reading. All passages were written with the specification to use language and…

Curriculum-based measurement of oral reading fluency (CBM-R) is used as an indicator of reading proficiency, and to measure at risk students' response to reading interventions to help ensure effective instruction. The purpose of this study was to compare model-based words read correctly per minute (WCPM) scores (computerized oral reading…

The Indiana Department of Education's (IDOE's) Accessibility and Accommodations Information for Statewide Assessments is intended for school-level personnel and decision-making teams as they prepare for and implement Indiana statewide assessments. Information is provided for school personnel as a reference to inform guidance on universal features,…

As a spoken word unfolds over time, similar sounding words ("cap" and "cat") compete until one word "wins". Lexical competition becomes more efficient from infancy through adolescence. We examined one potential mechanism underlying this development: lexical inhibition, by which activated candidates suppress…
