This report presents findings from two studies examining accommodations policies and research on alternate assessments based on alternate academic achievement standards (AA-AAAS). This policy analysis and literature review revealed several key insights about accommodations for AA-AAAS, with far-reaching implications for policy, practice, and…

Assessment accommodations are used globally in higher education systems to ensure that students with disabilities can participate fairly in assessment. Even though assessment accommodations are supposed to promote access, not success, they are commonly portrayed as potentially being "cheating" in that they provide certain students with…

In scholarly research, disabilities are predominantly understood as something that obscures assessment rather than enriches it. In this study, I examine how research on assessment adjustments (e.g. extra time in tests and separate testing rooms) portrays disabled students. I discuss how this area of research plays a role in constructing an image…

Research on test accommodations provides valuable information that informs policy and practice. This report presents a synthesis of the research literature published in 2022 on testing accommodations for U.S. elementary and secondary students (K-12). The National Center on Educational Outcomes (NCEO) has reported on accommodations research since…

Timed examinations continue to be a common educational assessment method employed to evaluate a student's knowledge, ability and skills in their subject area. Extra time is the most common adjustment that students with specific learning difficulties (SpLD) are granted in these exams. This adjustment aims to provide students with SpLD parity with…

To help ensure that assessments are properly administered, states have developed policies about who can administer or proctor assessments, and the training they must have. This report presents the findings of our analysis of states' 2021 policies on the qualifications and requirements for test administrators, proctors, and accommodations providers…

This systematic review investigated the topics studied and reporting practices of published meta-analyses in educational measurement. Our findings indicated that meta-analysis is not a highly utilized methodological tool in educational measurement; on average, less than one meta-analysis has been published per year over the past 30 years (28…

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 2019. During 2019, 11 research studies were published on the topic of testing accommodations…

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…

The purpose of this report is to present a synthesis of the research on test accommodations for U.S. elementary and secondary students (K-12) published in 2018. The academic literature described here encompasses empirical studies of performance comparability, investigations into accommodations use, implementation practices, and perceptions of the…

In the fall of 2017, ACT began providing a limited number of supports (also known as accommodations) to English Learner (EL) students in the US taking the ACT® test. The goal of the supports is to remove construct-irrelevant variance in students' scores related to limited English proficiency and allow students to more accurately demonstrate their…

Clinical Question: Among school-age children who speak AAE (P), does the use of dialect scoring modifications (I), when compared to traditional scoring methods (C), yield more reliable identification of true language disorders (O)? Method: Structured Review. Study Sources: Google Scholar and ASHAWire. Search Terms: (1) "dialect" OR…

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…
