This investigation scrutinizes the relative effectiveness of individual versus bundled accommodations -- specifically, breaks and extended time (ET) -- on the performance, behaviors, and attitudes of eighth-grade students with disabilities during the 2017 National Assessment of Educational Progress (NAEP) digital math test. Through a detailed…

Background/Context: Some observational studies involve multiple layers of treatment selection, specifically in the context of the extended time accommodation (ETA) for English language learners (ELLs). In ETA settings, the first selection occurs due to the eligibility rule, where students whose ELL English proficiency is below a certain threshold…

Although inclusion generally affects students with special educational needs positively, it remains unclear whether specific integrative school measures have beneficial or detrimental effects on their academic performance and perceived inclusion. Unlike previous studies, the present paper differentiates between various types of integrative school…

This study analyzed performance, process, and survey data of eighth graders with learning disabilities (LDs) who took the 2017 National Assessment of Educational Progress (NAEP) digital math test. Compared with students with LDs who did not receive extended time accommodations (ETAs), students with LDs who received and used ETA scored…

Extended testing time is a common accommodation given to students with disabilities. However, little is known about whether students who are eligible for the accommodation actually use it, and with what effect. The present study used process data available from the digitally delivered 2017 National Assessment of Educational Progress (NAEP)…

Traumatic brain injury in childhood (TBI) is a chronic health condition. As decreased memory, language, and rapid psychomotor impairments are known to accompany pediatric TBI (Babikian et al., 2011), students who have experienced a moderate-to-severe TBI are at particular risk for academic deficits, including writing difficulties. The purpose of…

The overuse of test accommodations (e.g., test readers, extra time, and calculators) for students with disabilities is a potential means of gaming the accountability system because it can inflate proficiency gains. However, no direct evidence on this problem exists, and findings on whether or not test accommodations improve test scores are…

Using two states' grades 3 through 8 state assessment databases, this study documents the extent to which students were assigned testing accommodations for ELA or mathematics in only one of two consecutive years. The percentage of students with disabilities who were assigned accommodations in the current year only or in the prior year only in a…

Students with autism spectrum disorder are being educated in the general education setting at a growing rate. With the increase in the number of children identified with autism compounded with the legal mandates to educate students with disabilities alongside their peers in the least restrictive environment, it is imperative that general education…

This is the 22nd report by the National Center on Educational Outcomes (NCEO) that describes how states publicly report assessment data for students with disabilities in K-12 schools in the United States. The purpose of this report is to examine the extent to which states reported 2018-19 assessment data for students with disabilities "to the…

West Virginia uses multiple state assessments to measure student achievement and inform program decision-making. The Individuals with Disabilities Education Improvement Act of 2004 requires participation of students with disabilities in statewide assessments to be consistent with the Elementary and Secondary Education Act of 2001 and current with…

When studying differential item functioning (DIF) with students with disabilities (SWD) focal groups typically suffer from small sample size, whereas the reference group population is usually large. This makes it possible for a researcher to select a sample from the reference population to be similar to the focal group on the ability scale. Doing…

This study examined the effects of explicit instruction in the SOLVE Strategy on the mathematical problem solving skills of six Grade 8 students with specific learning disabilities. The SOLVE Strategy is an explicit instruction, mnemonic-based learning strategy designed to help students in solving mathematical word problems. Using a multiple probe…

West Virginia uses multiple state assessments to measure student achievement and inform program decision making. States are required to provide guidance for appropriate participation of all students, including those with English Learners and those with disabilities, in required state assessments. The West Virginia Department of Education has…
