The purpose of this review is to investigate sign language assessments in use as a tool for evaluating the linguistic abilities for job related requirements for bilingual professionals. Each corresponding sign language assessment will be discussed in terms of its original purpose, content, how it is used today, followed by a discussion of its psychometric properties via strengths and weaknesses. In some cases, when available, a discussion of the background in regards to test development will be given. Psychometrically sound assessments will allow a more consistent evaluation of the professionals who support the Deaf community. In terms of research, having normed measures will lead to an increase in research to improve pedagogical practices and the delivery of educational services.

In the United States, students enrolled in an American Sign Language (ASL) Interpreter Education Program (IEP) are encouraged to achieve interpreter certification upon completion of the program. Obtaining the certification ensures employers they are hiring qualified personnel. A critical examination of assessments used by IEPs may result in formulating strategies that prepare students to pass the state-based assessments by graduation. A review of Program Learning Outcomes (PLO) and the way in which these are assessed should be undertaken in order to ensure that effective Student Learning Outcomes (SLO) are created to parallel appropriate stages of language development. Knowledge of Language Assessment Literacy (LAL) will assist in the development of well-defined and accurately-based objective assessments that are both valid and reliable. Targeting specific linguistic components combined with the usage of the cognitive domain of Bloom's Taxonomy for teaching and assessing learning outcomes will provide a clear means for developing assessments. Utilizing Bloom's Taxonomy, the development of assessments start at lower order cognitive processing and progressively moves to higher order (Marzano & Kendall, 2006). An examination of how using Bloom's Taxonomy assists in the development of assessments is outlined.
