Increased levels of burnout have been demonstrated for teachers and special education teachers (SETs) over the 20 past years. Since 1984, Maslach, Jackson and Leiter provided a framework for conceptualising burnout within three dimensions (emotional exhaustion, depersonalisation, personal accomplishment). This study aimed to verify the hypothesis that a reform implementation influences the three dimensions of the burnout among SETs in Switzerland. In order to meet the objective of the study, a cross-sectional research was conducted over two measurements times -- before and after the entry into force of the reform -- using the Maslach Burnout Inventory. The sample included 345 SETs for a response rate of 61.9% (T1 = 169; T2 = 176). Results show three essential outcomes: SETs show low levels of emotional exhaustion and depersonalisation but a level of personal achievement in the zone at risk. The reform implementation has not influenced the perceived health at work in the sample. SETs assess generally their health in a positive manner.
