Support technologies are a key concept that refers to the technical tools helpful in recovery, rehabilitation and education of people with disabilities. They play an important role in achieving effective communication with others and especially in schools, in educational communication. This study examines the main support technologies used with hearing impaired students in order to enable them to communicate effectively in school and successfully participate in educational programs. Also, in relation to the use of supportive technologies the teacher's scientific beliefs about the best educational communication approach (gestural, oral or total) is examined. In order to assess the study variables two questionnaires was administrated to 20 teachers for deaf from CSEI C-tin Pufan Timisoara. Results revealed that the teachers adopt the total communication model, with accent on bilingualism, and except hearing aids, they do not use other communication support technologies.
