The findings of this study suggest that it is important to give staff members the opportunity to learn new practices and to explore the thinking that underpins the actions they perform during communication training.

Purpose – This paper aims to evaluate the role of the supervisor's support on the effectiveness of a communication training program targeted at staff members who work with individuals who have profound and multiple learning disabilities. Design/methodology/approach – The aim was to explore which aspects of supervisory support influenced the staff members to participate in the programme and the results for the on-going effects of the training. Findings – Staff members reported a need for more supervisory support to maintain the results of the training and to disseminate the new practices to non-trained staff. Originality/value – Although supervisory support seems to benefit staff members during their participation in training programmes, even careful planning and execution of this support cannot ensure its continuation after the training is finished.
