Development, Adaptation, and Norming of ASL Proficiency Test Assessment Tool

ID: 3431
Status: Ongoing
Start date: September 2011
End Date: July 2019


The purpose of this study is to adapt, pilot, and standardize the Assessing British Sign Language (BSL) Development Receptive Skills Test (1999) and the Assessing British Sign Language Development Production Test (2009) for use in American Sign Language (ASL) to establish standardized, norm-referenced measures of ASL skills. The study will build on previous work involving the adaptation of the Assessing BSL Development Receptive Skills Test. This test has been translated, modified, and pilot tested, and the findings support ongoing test adaptation (2009). The Assessing BSL Development Production Test has not been adapted for use in other signed languages; however, it can potentially be adapted to any language. Procedures for adapting the Production Test include developing analysis (scoring) guidelines geared to the specific grammatical features of ASL and pilot testing this version of the test with approximately 40 children, ages 4-12 years. The collection of normative data for both the ASL Receptive Skills Test and the ASL Production Test will require access to larger numbers of native users of ASL levels between 3 and 12 years. It is essential that the children participating in the initial normative testing be native ASL users, or more specifically, that they have been exposed to ASL from birth (typically deaf children with deaf parents). Further normative testing will include a more heterogeneous sample of deaf children representing the broad range of ASL access and acquisition.
