PURPOSE: to verify the media influence on the knowledge of teachers in the municipal, state and private schools about stuttering, especially in childhood stuttering and describe the posture of teachers towards it. METHOD: the first experiment was carried from October 2009 to March 2011 with 300 teachers from the state, municipal and private schools. It was applied a questionnaire with questions on the knowledge and posture of teachers toward stuttering. It was made a descriptive statistical analysis and chi-square test (p<0,05). The second experiment was descriptive in which a survey was conducted about media and campaigns that could have reached the teachers participating in the research. RESULTS: there was no statistically significant difference in responses by type of school and teacher training. Most teachers answered "do not know" on issues specific to stuttering. The majority, 95% believed that stuttering can be cured and the speech therapist is the professional most often mentioned for referral for children who stutter. Two not-governmental campaigns and nine programs about stuttering in the studied region were found. CONCLUSION: the content questioned to the teachers was presented to the public at different moments by specialized professionals, however it seems it has not been enough to significantly modify the teachers' perception on stuttering.
