Advocates for people with disabilities in San Francisco are scheduled to rally Wednesday against the continued use of the “R-word,” according to the San Francisco Unified School District.

Former state Sen. Mark Leno and Board of Education member Rachel Norton will join Access SFUSD, a program for older students with disabilities, at City Hall around 10 a.m., according to the district.

The rally is part of a national effort to end the use of the word called Spread the Word to End the Word. According to the movement, the “R-word,” or retard, is a form of bullying that many young Americans still use.

“Language affects attitudes and attitudes affect actions,” the Facebook event for Wednesday reads. “We pledge to use respectful, people-first language.”
