The Miranda Warning and Waiver ASL (MWWT-ASL) is a bilingual test constructed and administered to three groups of deaf adults in postsecondary education (n = 34) who differed on bilingual (ASL/ English) proficiency, IQ, and number of years using sign language. The deaf adults read the MWW in English print and viewed it on a DVD as the Miranda was translated into ASL by a certified legal interpreter. Participants' retelling tasks were videotaped. The videotapes were then transcribed and back-translated into English, compared to the Miranda rights in English, and scored on a five-point scale (0-4).Age, IQ, reported years of using sign language, and English-reading grade level were found to be strongly and positively correlated to retelling scores on the MWWT-ASL. Further, findings revealed that deaf adults who are reading at the eighth-grade level or below would be linguistically incompetent to understand the Miranda warning and waiver even if it is presented in both ASL and English.
