Although much research has been conducted on sustainable tourism and the education thereof internationally, a limited number of studies have focussed on education of sustainable tourism in South African secondary schools. A literature overview identified various approaches to the education of sustainability on the international front. Despite South Africa’s reliance on the tourism industry, the concept of sustainability has received little focus in classrooms where this pertinent issue should be receiving attention in order to ensure that future sustainability is ensured in the South African tourism industry. From the literature overview it was possible to identify topics pertaining to sustainability in the Tourism Curriculum and Assessment Policy Statement implemented in the Further Education and Training Phase (FET) in South African secondary schools. These assisted in the development of the research tool for this study. The New Ecological Paradigm (NEP), an instrument used to establish the level of environmental concerns of groups of people, also provided guidance in the development of the research tool. The primary objective of this study is to investigate the perceptions of Tourism educators in secondary schools towards sustainability. A framework to investigate this was developed and three hypotheses formulated. To give effect to this, an empirical investigation was conducted. Tourism educators who were successful in their application to mark 2014 National Senior Certificate Tourism examinations were included in the sample of this study. The result of the descriptive statistics performed on the data showed that the level of education of the respondents was the main contributing demographic that impacted on their perceptions of sustainable tourism. It is, however, of concern to note that a very low percentage of the respondents (6.2%) have received formal training in Tourism. This situation should be cause for concern for Tourism education in the Eastern Cape. Two of the three hypotheses were accepted. The researcher believes that specialised subject relevant training is required to empower educators to teach sustainable tourism in the South African secondary school classrooms in order to ensure future sustainability in the tourism industry of South Africa.
