This study reports an independent investigation of the psychometric properties of Desired Results Developmental Profile (DRDP), a teacher-rated measure of school readiness for preschool-aged children. In a sample of 2,031 low-income, 3- to 5-year-old children attending Head Start, we tested three measurement models: a higher order one-factor…

Research indicates that the performance-gap between English Language Learners (ELLs) and their non-ELL peers is partly due to ELLs' difficulty in understanding assessment language. Accommodations have been shown to narrow this performance-gap, but many accommodations studies have not used a randomized design and are based on relatively small…

This study examines the power of cognitive and noncognitive variables to predict students' performance in algebra. We investigated students' prior year's assessment scores and demographic characteristics to predict eighth-grade algebra scores. Using California statewide assessment data, we explored predictive factors in three regression models.…

This study explores factors that affect the accessibility of reading comprehension assessments for students with disabilities in grade 8 public school classrooms. The study consisted of assessing students using reading comprehension passages that were broken down into shorter "segments" or "chunks" in order to assess the…

High-stakes decisions for the instruction and assessment of English language learner (ELL) students are made based on the premise that ELL classification is a valid dichotomy that distinguishes between those who are proficient in the use of the English language and those who are not. However, recent research findings draw a vague picture of the…

Given the changing landscape of educational accountability at the local, state, and national levels, and the changes in the uses of the National Assessment of Educational Progress (NAEP), including the evolving uses of NAEP as a policy tool to interpret state assessment and accountability systems, an explicit statement of the current and potential…

This study compared performance of both English language learners (ELLs) and non-ELL students in Grades 4 and 8 under accommodated and nonaccommodated testing conditions. The accommodations used in this study included a computerized administration of a math test with a pop-up glossary, a customized English dictionary, extra testing time, and…

There are major issues involved with the disaggregated No Child Left Behind (NCLB) Act in terms of its adequate yearly progress reporting for students with limited English proficiency (LEP). Inconsistent LEP classification, as well as the sparse population of LEP students in many states, threatens the validity of adequate yearly progress…

Explores methods of assessing opportunity to learn (OTL) and presents data collected as part of a pilot study of an eighth-grade statewide mathematics assessment to explore issues of validity. Investigates the integrity of various dimensions thought to constitute OTL, analyzes the relationships among teachers' and students' self-reports, and draws…

This study examines the effect and validity of accommodations for limited English proficiency (LEP) students in the National Assessment of Educational Progress (NAEP) and the impact of language factors on the assessment and accommodation of these students. Results indicate that accommodations used in NAEP did not reduce the performance gap between…

Assessments in English that are constructed for native English speakers may not provide valid inferences about the achievement of English language learners (ELLs). The linguistic complexity of the test items that are not related to the content of the assessment may increase the measurement error, thus reducing the reliability of the assessment.…

Results from a performance assessment in which 68 high school students wrote essays support the use of latent variable modeling for estimating reliability, concurrent validity, and generalizability of a scoring rubric. The latent variable modeling approach overcomes the limitations of certain conventional statistical techniques in handling…

Describes research on the development of a measure of student metacognition. The brief, domain-independent measure serves as a collateral measure in construct validation, supporting exploration of the self-regulatory demands of performance assessment. Results show that metacognition can be directly and explicitly measured in the context of…

A fair and valid assessment for every child, as mandated by legislation such as the No Child Left Behind Act (NCLB) of 2001 and the Improving America's School Act of 1994, must consider the complexity inherent in assessments for subgroups of students. Due to the rapid growth of the population of English language learners (ELLs) in the United…
