About the American Sign Language Proficiency Interview

The Praxis® program has made arrangements for the following candidates to take the American Sign Language Proficiency Interview (ASLPI) delivered and evaluated by ASL Diagnostic and Evaluation Services of Gallaudet University:

  • candidates who plan to teach American Sign Language (ASL) as a language other than English
  • candidates who plan to teach students who are deaf or hard of hearing

The 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 an 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. The interview is conducted face to face at Gallaudet in Washington, D.C., and via videophone from other locations.
