This guide is maintained by the National Center on Disability and Journalism. From the NCDJ: "As language, perceptions and social mores change rapidly, it is becoming increasingly difficult for journalists and other communicators to figure out how to refer to people with disabilities. Even the term “disability” is not universally accepted. This style guide, which covers dozens of words and terms commonly used when referring to disability, can help. The guide was developed by the National Center on Disability and Journalism at Arizona State University’s Walter Cronkite School of Journalism and Mass Communication and was last updated in the summer of 2021."
