The Sign Language Proficiency Interview (SLPI) involves a one-to-one conversation in sign language between an interviewer and candidate/interviewee. Interview content varies according to the background, job responsibilities, schooling, and other interests of each SLPI candidate/interviewee.
The SLPI was adapted by Drs. Bill Newell and Frank Caccamise from the Language/Oral Proficiency Interview (L/OPI), an interview technique for assessing spoken language communication skills. Just as the L/OPI may be used to assess a variety of spoken languages, the SLPI may be used to assess a variety of sign languages. When used to assess ASL skills the SLPI is labeled the SLPI:ASL. In its use by the US Peace Corps in assessing Kenyan Sign Language (KSL), it is labeled the SLPI:KSL.
SLPI interviews are recorded and subsequently rated independently by SLPI raters. The basis for ratings is the SLPI Rating Scale, a standard scale based on the sign language communication skills of highly skilled, knowledgeable native/native-like signers.
The goal of the SLPI is to assess how well people are able to use sign language for communication, and, as appropriate, to use this information to assist people in development of their sign language communication skills.
Bill Newell and Frank Caccamise wrote or consulted on the writing of many documents in this website.
