Sustainable development is an interdisciplinary structure that includes the dimensions of environment, economy and society. The aim of this research was to determine the sustainable development awareness of science, social studies and primary school teachers. The research designed with the survey approach was carried out with 2982 teachers working in different regions of Turkey in 2019. In the research, Sustainable Development Awareness Scale consisting of 3 sub-dimensions and 36 items developed by Atmaca, Kiray and Pehlivan (2019) was used. Significance level was taken as 0.05 in the analyses that examined the signification between the groups. As a result of the research, no significant difference was found between the teachers' sustainable development awareness and their branches and years of service, while a significant difference was found between the teachers' ages and gender and their sustainable development awareness scores.
