The writing assessment for deaf and hard-of-hearing (D/HH) children is an assessment tool aimed at measuring D/HH and hearing children’s productive syntax of written Chinese, and is designed to capture the development of Chinese writing by D/HH children, and also to identify specific difficulties faced by individual D/HH children. The written data are elicited by picture stimuli. D/HH and hearing students are asked to write about 300 characters (punctuations included) based on the picture stimulus, and the time limit is 30 minutes. The assessment involves a multi-dimensional analysis, including impressionistic rating, linguistic analysis at different levels, narrative analysis and also error analysis. The assessment could provide teachers and speech therapists a valid, comprehensive and convenient tool to assess children’s written language development.
