A sample of elementary and high school-age deaf students in special education programs in the Australian state of Queensland using Australasian Signed English (ASE) undertook the Test of Syntactic Abilities and wrote a story in response to a wordless picture sequence. A number of analyses of the test scores and of the written language of their stories was undertaken. It was found that classroom use of ASE was of benefit to these students in developing English and telling a story in writing but that there are complex aspects of syntax that require special teaching. The implications for the use of signed English systems and the teaching of English to deaf students who use signed English communication are examined.
