This paper describes the development of a new Test of Child Speechreading (ToCS) that was specifically designed to be suitable for use with deaf children. Speechreading is a skill which is required for deaf children to access the language of the hearing community. ToCS is a child-friendly, computer-based, speechreading test that measures speechreading (silent lipreading) at three psycholinguistic levels: words, sentences and short stories. A detailed description of the design, procedure and validity of ToCS is provided. 86 severely and profoundly deaf and 91 hearing children aged between 5 and 14 years participated in the standardisation study. Deaf and hearing children showed remarkably similar performance across all subtests on ToCS. Speechreading improved with age but was not associated with non-verbal IQ. For both deaf and hearing children, performance on ToCS was significantly related to reading accuracy and reading comprehension.
