This study, aiming to determine the competency perceptions of teachers regarding multiculturalism of teachers working at the secondary schools in Tokat province, Turkey, employed a descriptive survey model. The study population was 341 teachers working at secondary education institutions in Tokat province in the 2014-2015 school year. Data was collected using a questionnaire consisting of seven questions to collect personal information, the "Multicultural Competency Perceptions Scale" developed by Baskaya & Kagnici (2011), and an open-ended question. Quantitative data was analyzed using SPSS 20 program, and qualitative data was analyzed using content analysis technique. From the analyses, the scores regarding the multiculturalism competency perceptions of teachers were found to be positive and above the mean score. While the multiculturalism competency perceptions of teachers did not differentiate according to gender, workplace, faculty of graduation, age, or seniority, they differed according to the residential area, and subject. The findings obtained through the qualitative data showed that although teachers had positive perception of their competency regarding multiculturalism, this was not reflected to any great extent in the classroom.
