Bhutanese Sign Language (BhSL; Drukgi Lagdai Khakay in Dzongkha) is the indigenous sign language of Bhutan, used especially at the Wangsel Institute for the Deaf, Paro, Bhutan.
Bhutan set up the program for the deaf in a hearing school in Thimphu ca.
[1] Part of government funding for deaf education includes developing Bhutanese Sign Language as the language of instruction.
Development includes at least creating vocabulary for technical subjects,[2] and deciding on which regional signs to use where they differ.
[3] It is not clear if there are multiple sign languages in Bhutan, or merely local differences in vocabulary.
