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…

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…

Standardized achievement tests that are used for assessment and accountability purposes may not provide reliable and valid outcomes for English language learners (ELLs) because extraneous sources may confound the outcome of assessments for these students. Performance assessments, by contrast, may offer opportunities for these students to present a…

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…

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…

Recent attention to issues concerning the instruction and assessment of English language learner (ELL) students has placed them among the top national priorities in education. Policy has noticeably shifted from exclusion to inclusion of ELL students in the assessment and accountability system. However, recent research on and practice in the…

Research reports major concerns over classification and measurement for students with limited English proficiency (LEP). A poor operational definition of the English language proficiency construct and validity concerns about existing language proficiency tests are among these issues. Decisions on including LEP students in large-scale assessments…

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…

This publication reports the results of a research study on the feasibility and validity of various accommodations in the context of mathematics assessment. The study compared limited English proficiency (LEP) and non-LEP students' scores on 20 science items under three different conditions: standard National Assessment for Educational Progress…
