Previous research highlights that personal factors are more important than contextual factors in explaining teachers' behaviours in relation to learning participation. The present study explores the relationship between two personal factors (dispositional resistance to change and teachers' attitude towards continuing education) and the moderating role of conscientiousness on this relationship. The data have been gathered from 142 teachers from the field of special and public education, using three questionnaires: Revised Adult Attitudes Towards Continuing Education Scale, Resistance to Change Scale and IPIP-50. The main results show that, firstly, conscientiousness has a moderating role on the relationship between dispositional resistance to change and enjoyment of learning, and secondly, teachers in special education consider their continuing education as being more important than teachers in the regular system. Knowing this, we can predict and increase teachers' participation in continuing education and can improve training design.
