Sign Language Proficiency Interview (SLPI:ASL)

Overview

The Sign Language Proficiency Interview (SLPI:ASL) 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:ASL candidate/interviewee.

The SLPI:ASL was adapted by 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:ASL may be used to assess a variety of sign languages. For example, it is used in Kenya as SLPI:KSL, in South Africa as SLPI:SASL, and in New Zealand as SLPI:NZSL.

SLPI:ASL interviews are recorded and subsequently rated independently by SLPI:ASL raters. The basis for ratings is the SLPI:ASL Rating Scale, a standard scale based on the sign language communication skills of highly skilled, knowledgeable native/native-like signers. In application, a primary use of the SLPI:ASL has been 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. In the Evaluators’ Resources part of this website, Training Workshop Materials Sections 1, 5, 7 and 8 provide additional information about the SLPI Rating Scale, what the SLPI:ASL assesses, and SLPI:ASL use; and Section 10 provides information on connecting sign language instruction and SLPI:ASL results.

Frequently Asked Questions

The Sign Language Proficiency Interview (SLPI:ASL) Rating Scale is a standard scale for rating sign language communication skills that is based on highly skilled, knowledgeable native-like signers. Since each SLPI:ASL candidate's performance is compared to this standard scale, not other candidates, the SLPI:ASL is a criterion referenced test.

More about the SLPI:ASL Rating Scale (PDF)

The SLPI:ASL assesses a person's skills in using a natural sign language for communication (function), and it provides an analysis of a person's sign language vocabulary, production, fluency, grammar, and comprehension skills (form).

More about the SLPI:ASL assessments (PDF)

In 1980 at the Third National Symposium on Sign Language Research and Teaching in Boston, Protase Woodford from Educational Testing Services, Princeton, NJ, presented information about the Language/Oral Proficiency Interview, an interview technique for assessing spoken language communication skills. Based on Woodford's presentation, several individuals began to explore the application of interview techniques to the assessment of American Sign Language (ASL), including faculty from the College of Staten Island, Gallaudet University (then Gallaudet College), and the National Technical Institute for the Deaf (NTID). Our application at NTID was originally developed and piloted for evaluating the sign language communication skills of NTID faculty and staff, with the first formal implementation of the SLPI:ASL occurring for residential staff at the Louisiana School for the Deaf.

More about the SLPI:ASL history (PDF)

SLPI:ASL Training Workshops and implementation have occurred at more than 50 academic and vocational rehabilitation programs across the US and in Canada, Kenya, and South Africa.

This sub-section includes three MODEL Annual Sign Language Program Reports based on Florida School for the Deaf and the Blind (FSDB) and South Carolina School for the Deaf and the Blind (SCSDB) reports:

Annual Sign Language Program Reports are important to determining the fairness of expected sign language entry skill levels and standards/goals.

The MODEL 1 and MODEL 2 Annual Reports include information about SLPI services, the number and percentage of staff that have and have not achieved their sign language skill level standards/goals, and participation and success of staff below their goals in sign language instruction.

In addition, the MODEL 1 Annual Report includes an explanation of how SLPI results are used to help ensure staff members with similar sign language skill levels are placed together in ASL courses. This ASL course placement criteria is designed to help ensure course content is appropriate for the ASL skill levels of staff members and to help avoid the frustration that may arise for both instructors and staff members when staff members taking an ASL course have a wide range of ASL skills. This placement criteria is also helpful to instructors and staff members in making a direct connection between the ASL assessment tool being used, the SLPI, and ASL instruction.

The MODEL 3 annual report, which is based on a quarterly reporting process, includes a narrative summary that refers to two tables that summarize sign language program information for each of the four quarters of the fiscal year (FY) being reported. In addition, comparisons to past FY results and totals over several FYs may be included in the narrative summary.

When interviewing a candidate, it is best to keep the following in mind:

  1. Your goal is to bring out the candidate’s best ASL. You are the candidate’s ally.
  2. Model ASL for the candidate. This means:
    • Don’t code-switch to more English-based signing.
    • Mouth movements must match natural ASL signing.
  3. If candidate doesn’t understand:
    • Repeat the question just as you signed it the first time.
    • Repeat, but more slowly.
    • Re-phrase the question with ASL syntax (don’t change to English syntax).
    • Rephrase again…slow down.
    • Do not use more fingerspelling.
  4. Please be aware that the candidate may be anxious, as is normal in a testing context. If you feel frustrated with the candidate, showing it will only increase their anxiety. Never show your frustration, no matter what.

    • Work

    • Hobbies/leisure activities

Workshop training room set-up (pdf)

Diagram of setup of a training room

Interview room set-up

Below is an example of setting up the interview room to make good use of one camera. Notice a few things about this arrangement:

  • This is for a right-handed candidate; the candidate sits on the right and the interviewer on the left. This is best for viewing the candidate's signing and, especially, fingerspelling.
  • The camera's main capture is of the candidate; however, it's pointed in such a way that it will also capture the interviewer's facial expressions. This helps the raters judge the quality of the interaction. In particular, it allows the raters to know when the candidate's signing is not clear to the interviewer.
  • Behind the candidate is a clock. The interviewer can glance at the clock discretely to help judge both the overall length of the interview and the three segments (work/study, family, and leisure activities/hobbies).
  • There are no alligators anywhere in the interview room.

These details are discussed in Paper 6: Angles and Other SLPI Recording Guidelines in Training Notebook Section 7.

The documents below provide information and materials important to planning and hosting workshops for training potential SLPI:ASL Team members. It includes both PDF and Word versions of the SLPI:ASL Training Workshop: Planning, Implementation, and Follow-Up document. The PDF version maintains the appropriate format for this document, but it cannot be edited. The Word version can be edited to fit the needs of each program that sponsors an SLPI:ASL Workshop, but the appropriate format may not be maintained when posted in a website. Therefore, programs can refer to the PDF version to assist them with the proper format when they make changes to the Word version to fit their application of the SLPI:ASL.
