The use of accommodations is often recommended to remove barriers to academic testing among English Learners (ELs). However, it is unclear whether accommodations are particularly effective at improving ELs' test scores. A growing foundation of empirical work has explored this topic. We conducted a meta-analysis that examined several possible…

This report provides an update on the state of the research on testing accommodations. Previous reports by the National Center on Educational Outcomes (NCEO) have covered research published since 1999. In this report, we summarize the research published in 2020. During 2020, 11 research studies addressed testing accommodations in the U.S. K-12…

This report provides a snapshot of how accommodated tests for students with disabilities, accessibility, alternate assessments, and other related issues were addressed in states' test security policies for 2020-21. Strong test security policies and procedures are needed to help ensure the integrity and validity of state assessments, yet some test…

This research synthesizes studies that used a Digitalized Interactive Component (DIC) to assess K-12 student mathematics performance during Computer-based-Assessments (CBAs) in mathematics. A systematic search identified ten studies that categorized existing DICs according to the tools that provided language assistance to students and tools that…

The purpose of this document is to provide information and advice to support states in meeting USED Peer Review Requirements related to demonstrating the comparability of test scores across various devices used for technology-based testing. The document is divided into four main sections. In the first section, we discuss and define the…

The purpose of this report is to present a synthesis of the research on test accommodations published in 2015 and 2016. We summarize the research to review current research trends and enhance understanding of the implications of accommodations use in the development of future policy directions, to highlight implementation of current and new…

Among the several forms of accommodations used in the assessment of English language learners (ELLs), language-based accommodations are the most effective in making assessments linguistically accessible to these students. However, there are significant challenges associated with the implementation of many of these accommodations. This article…

A report analyzing how accommodated tests, and students with disabilities and the assessments they take, are addressed in state test security policies -- a subject about which little is known. This analysis was conducted to partially fill this gap. The report provides a snapshot of how accommodated tests for students with disabilities, alternate…

The authors conducted a qualitative meta-analysis of the research on assessment accommodations for students who are deaf or hard of hearing. There were 16 identified studies that analyzed the impact of factors related to student performance on academic assessments across different educational settings, content areas, and types of assessment…

Computers are revolutionizing almost every aspect of society and testing is no exception. Delivering tests on a computer often improves exam security, testing efficiency, and scoring, and it often allows for measurement of knowledge, skills, and abilities that cannot be measured using traditional assessment formats. One of the most widely cited…

With pressure to find more cost effective and less labor-intensive approaches to testing, states are seeing computer-based testing as a way to address the increasingly challenging prospect of assessing all students in a state at nearly all grades. Unfortunately, most states have not specifically considered the needs of students with disabilities.…

This article explores the relationship between the inclusion movement and the development of national standards for "all students," and outlines their implications for technology-assisted improvements in assessment of students with disabilities. Testing accommodations, such as input/output adaptations, can be facilitated with technology, and new…
