Rosa's Law [1] is a United States law which replaced instances of "mental retardation" in law with "intellectual disability". The bill was introduced as S.2781 in the United States Senate on November 17, 2009, by Barbara Mikulski (D-MD). It passed the Senate unanimously on August 5, 2010, then the House of Representatives on September 22, and was signed into law by President Barack Obama on October 5. [2] The law is named after Rosa Marcellino, a girl with Down syndrome who was nine years old when it became law, and who, according to Barack Obama, "worked with her parents and her siblings to have the words 'mentally retarded' officially removed from the health and education code in her home state of Maryland." [3]
Words such as idiot and moron were common in court documents and diagnosis throughout the early 1900s. [4] According to the report submitted to the Senate by the Committee on Health, Education, Labor, and Pensions, "The committee believes that the terms "mentally retarded," "mental retardation," and variations of these terms, to describe individuals with intellectual disabilities are anachronistic, needlessly insensitive and stigmatizing, and clinically outdated."
