What is ASLPI?

The American Sign Language Proficiency Interview (ASLPI) is a holistic language evaluation used to determine global ASL proficiency. The basic precept in this type of evaluation is to find out through a face-to-face interview what an individual can do with the target language at a given point in time. The ASLPI is a 20-25 minute video recorded interactive dialogue between the examinee and the interviewer. The interview is rated by a team of evaluators and examinees are awarded an overall proficiency level on a 0-5 rating scale. Language proficiency evaluation was originally developed by the Foreign Service Institute (FSI) of the US Department of State and has been used by the government for decades. Adaptations to the language proficiency evaluation were made with respect to ASL and the ASLPI was born. The ASLPI is utilized by agencies, schools, universities, programs and employers.
