The grades K-2 Florida Center for Reading Research (FCRR) Reading Assessment (FRA) consists of computer-adaptive alphabetic and oral language screening tasks that provide a Probability of Literacy Success (PLS) linked to grade-level performance (i.e., the 40th percentile) on the word reading (in kindergarten) or reading comprehension (in grades…

The comprehension section of the "Nelson-Denny Reading Test" (NDRT) is widely used to assess the reading comprehension skills of adolescents and adults in the United States. In this study, the authors explored the content validity of the NDRT Comprehension Test (Forms G and H) by asking university students (with and without at-risk…

In this technical report, we provide the results of a series of studies on the technical adequacy of the early reading measures available on the easyCBM[R] assessment system. The results from the two-level hierarchical linear growth model analyses suggest that the reliability of the slope estimates for the easyCBM[R] reading measures are strong,…

In this technical report, we provide reliability and validity evidence for the easyCBM[R] Reading measures for grade 2 (word and passage reading fluency and multiple choice reading comprehension). Evidence for reliability includes internal consistency and item invariance. Evidence for validity includes concurrent, predictive, and construct…

We evaluated the validity of DIBELS ("Dynamic Indicators of Basic Early Literacy Skills") ORF ("Oral Reading Fluency") for predicting performance on the "Florida Comprehensive Assessment Test" (FCAT-SSS) and "Stanford Achievement Test" (SAT-10) reading comprehension measures. The usefulness of previously…

Despite recent research findings that implicate a long list of student variables that predict reading success or failure, these predictor variables have not been considered in the context of contemporary models of multitiered schoolwide reading intervention. This longitudinal, retrospective study follows 668 kindergarten and first-grade students…

With the recently passed Individuals with Disabilities Education Act (2004), federal law encourages monitoring student progress and gauging responsiveness to instruction. The Test of Silent Word Reading Fluency (TOSWRF; Mather, Hammill, Allen, & Roberts, 2004) is a group-administered test that holds promise for monitoring student progress.…

Issues related to validity and bias in psychological tests in general and specifically to the Stanford Achievement Test--Special Edition for Hearing Impaired Students (SAT-HI) are discussed. Questions regarding content validity and the lack of criterion-related data on the SAT-HI are raised. (Author/DB)

Validity and reliability issues in standardized testing of students of limited English proficiency (LEP) were studied. Existing data from four different school sites were obtained for LEP and non-LEP students for three different standardized tests, the Stanford Achievement Tests (Ninth edition), the Iowa Tests of Basic Skills, and the Language…

The quality of reading comprehension and mathematics instruction was explored in five urban middle schools using the Instructional Quality Assessment (IQA) toolkit (N = 34 teachers). The IQA is comprised of protocols for rating observed instruction and the quality of teachers' assignments with student work. The purpose of this research was to…

A taxonomy was developed for classifying instructional materials in fourth grade mathematics, as well as the content of actual classroom instruction and of achievement tests. The taxonomy is defined by the intersection of three factors and results in 468 cells: (1) mode of presentation (for example, use of graphs, tables, story problems)--3…

Stanford Achievement Test scores of 1,434 elementary-level students already placed in either regular or special education programs were arranged according to four cutoff points: 20th, 15th, 10th, and 5th percentiles. This identification method, setting the cutoff at the 5 percent level, is proposed as a preliminary screening device for special…
