Thai Sign Language (TSL) or Modern Standard Thai Sign Language (MSTSL) is the national sign language of Thailand’s Deaf community and is used in most parts of the country by the 20% of the estimated 56000 pre-linguistically deaf people who go to school. Thai Sign Language was acknowledged as the national language of deaf people in Thailand in August 1999 in a resolution signed by the Minister of Education on behalf of the Royal Thai Government.
