This article provides an executive summary of the American Psychological Association's (APA's) revised Guidelines for Assessment and Intervention With Persons With Disabilities. The revision was requested by the Committee on Disability Issues in Psychology and was approved by the APA Council of Representatives in February 2022. The task force updated and expanded the guidelines' empirical bases; squarely situated the guidelines in a changing sociocultural landscape (reflected in discussions of disability models, biases and barriers, language use, intersectionality, and respectful and fair assessment and intervention); and added many concrete suggestions for conceptualizing disability and working with disabled clients and their support systems. In this executive summary, we include key points from each of the 23 guidelines. (PsycInfo Database Record (c) 2023 APA, all rights reserved).
