Tanzanian Sign LanguagePrint
In some deaf institutions, sign language is not taught; caretakers want deaf children to speak and lip-read to fit into society more easily. All domains. All ages.
Historically, schools for the deaf used different sign languages. More recently, Tanzanian sign language was standardized by the Tanzania Association for the Deaf (CHAVITA) which is attempting to use it in most schools for the deaf. Primary schools for deaf children since 1963. About 5% of deaf children attend school. Committee on national sign language. Little research.
