Historically, this was common language in the profession and broader society. Because of its broad and common use, outdated language may also appear in other RISP products. The "R-word," as we understand it now, is an ableist slur. Our previous language does not reflect the RISP team's ongoing commitment to social inclusion of people with IDD.enEnvironmental Characteristics of Residential Facilities for Mentally Retarded People in the United StatesOther
