A test of English language proficiency designed for administration to school children with severe disabilities is presented. The test packet contains a manual for test administrators, a five-page form for recording student testing data, and a score sheet. The manual offers an introduction to the instrument, including its rationale, definitions of English language proficiency under current California law, information on current practice in providing testing to this group, an overview of the history and development of the measure, and a description of its field testing. The test's validity and reliability are discussed briefly. Directions for test administration outline the necessary qualifications of the test administrator, procedures to be used when the informant is the primary caregiver or parent, directions for signing and non-signing hearing impaired students, specific directions for the receptive and expressive language portions of the instrument, notes on scoresheet use, assessment of students with a classification of "limited English proficient," and instructional implications. The instrument itself consists of brief instructions, a home language survey, parent interview form, and an observation instrument. (MSE)
