In Turkey, professional standards for teachers have recently been developed by the Turkish Ministry of Education in collaboration with universities, and these standards have begun to be taken into account in preservice and in-service training programs. The study reported in this article sought to determine the degree to which the professional standards for Turkish teachers of students with visual impairments were addressed during preservice training and the degree to which in-service teachers of visual impairments implemented these professional standards. The results of the nationwide survey showed that teachers faced problems in both attaining and implementing certain important knowledge and skill areas for teaching students with visual impairments.
