Sign language serves as a communication function for persons with hearing impairments.
Mastering sign language, as well as verbal, is important for the formation of the personality of the deaf student, his mental development and socialization.
By teaching sign language to deaf people along with verbal language, the educational institution prepares the student for life in two societies: the world of hearing people with verbal language and the macro-society of deaf people with sign language, as well as for their constructive interaction.
