Language Proficiency Interview

ASL Language Proficiency Interview (ASLPI) is an assessment tool used to determine ASL proficiency level, conducted by a qualified organization.

LPI is required by some schools, universities, agencies, employers and other programs to evaluate a candidate's language proficiency in a face-to-face interview. ASLPI certified interviewers and raters, who are native/fluent in ASL, have undergone training and years of ASLPI experience.

ASLPI consists of a structured interview of about 20-60 minutes of conversation, which is carried out between a candidate and a trained interviewer. ASL interviews are conducted either through videophone or in-person and recorded for raters.

The rater then evaluates a candidate's over performance in communicative competency including fluency, vocabulary, grammar, and comprehension. Then, the candidate is given an overall score, ranging from 0 (the lowest) to 5 (the highest proficiency).
