Turkish sign language interpreters are key to expressing themselves in many areas of life for hearing impaired individuals who use sign language as a communication language. For this reason, the language proficiency of Turkish Sign language interpreters is the determinant of accurate, effective and effective communication. However, it was necessary to determine the language proficiency of interpreters in line with the experiences gained from existing applications. As it is known, Turkish sign language interpreters have an important role in the access of the hearing impaired to information and services, the elimination of communication needs, their failure to lose rights and their equal participation in society.

Turkish sign language proficiency of the candidates who participated as a result of the exam is "A1,A2; B1,B2; C1,C2" levels.  In TİdYES, which has been held twice so far and a total of 296 people participated, 50 people were evaluated as successful at B2 level with a score of 75 or above.
