Curriculum-based measurement of oral reading fluency (CBM-R) is widely used across the United States as a strong indicator of comprehension and overall reading achievement, but has several limitations including errors in administration and large standard errors of measurement. The purpose of this study is to compare scoring methods and passage…

There is some evidence that reading and spelling are complementary processes. The purpose of this study was to investigate the extent to which contextualized spelling (i.e., spelling activities within the context of reading instruction) is used to support reading in first-grade core reading programs. Analysis of 75 lessons across five programs…

Despite prevalent use and practical application, the current and standard assessment of oral reading fluency (ORF) presents considerable limitations which reduces its validity in estimating growth and monitoring student progress, including: (a) high cost of implementation; (b) tenuous passage equivalence; and (c) bias, large standard error, and…

We present a method for data-based decision making at the school level using student achievement data. We demonstrate the potential of a national assessment database [i.e., the University of Oregon DIBELS Data System (DDS)] to provide comparative levels of school-level data on average student achievement gains. Through the DDS as a data source,…

"Success for All" ("SFA"®) is a whole-school reform model (that is, a model that integrates curriculum, school culture, family, and community supports) for students in prekindergarten through grade 8. "SFA"® includes a literacy program, quarterly assessments of student learning, a social-emotional development program,…

Lack of psychometric equivalence of oral reading fluency (ORF) passages used within a grade for screening and progress monitoring has recently become an issue with calls for the use of equating methods to ensure equivalence. To investigate the nature of the nonequivalence and to guide the choice of equating method to correct for nonequivalence,…
