ASL Diagnostic and Evaluation Services

Merrill Learning Center, Room 2200
Web:   Email:

ASL Diagnostic and Evaluation Services (ASL-DES) provides training, consultation and comprehensive measures of American Sign Language (ASL) proficiency and communicative competence. The data and information generated by ASL Diagnostic and Evaluation Services benefits not only individual language learning, but is also essential to Gallaudet University, institutions and governing bodies nationwide. Information pertaining to ASL proficiency is provided to ensure individuals have requisite language skills for (but not limited to):

  • Admission into academic programs
  • Core curriculum, practicum, internship and graduation
  • Professional opportunities and advancements

Information about the ASL-DES core services is outlined below.

Classroom Discourse Observation (CDO)

Web:            Email:

Classroom Discourse Observations (CDO) capture not only aspects of ASL, but also discourse techniques/pragmatics, heuristic functions, and whether the environment is visually optimized. A classroom-based assessment would also note students' comprehension of the faculty, and the faculty's comprehension of the students. ASL Diagnostic and Evaluation Services (ASL-DES) video records the faculty in the classroom and then analyzes the video recording to identify strengths and areas needing improvement in the areas of visually optimized environments, discourse, and pragmatics. The faculty is then provided a personalized feedback session which includes the opportunity to review and discuss the video recording.

CDO participants who need to improve the target scores are provided with tailored support to polish specific areas needing improvement that are identified in the CDO process.  The support includes tasks designed to enhance skills that will increase scores from the Pre to Post Classroom Discourse Observation.

Focused Topic Preparation (FTP)

Web:  Email:

This service is for individuals with more advanced ASL skills. Feedback and support is provided to "polish" a presentation, performance, vlog or pre-recorded video segment prepared for a specific purpose. Feedback is provided on specific language aspects as well as pragmatics.

American Sign Language Proficiency Interview (ASLPI)

Web:  ASL-DES    Email: 


The American Sign Language Proficiency Interview (ASLPI) is a holistic language evaluation used to determine global ASL proficiency at a given point in time. The ASLPI is a 20-30 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. Except for proficiency level 5, the scoring process sometimes results in the assignment of a plus value (+). This does not represent a midway point between two levels, but may be inferred to indicate that the examinee exceeds the requirements for a particular level but does not satisfy in all respects the requirements of the next higher level. This language proficiency evaluation is not tied to any one course or curriculum nor does it measure a single skill in the language.

For more information about the ASLPI including but not limited to the scheduling process, fees, preparation, and post-interview details, please visit the website.
