The importance of the headteacher as the initiator of innovation has already been mentioned briefly. The evidence suggests that it is usually the headteacher who takes the initiative in introducing innovations into the school, and even where this is not the case his support is necessary for any innovation proposed by a member of staff. It follows from this that the headteacher has the task of imparting his ideas for the innovation to the teachers who will be concerned, and of securing their participation. In turn, the teachers will react in some way to the proposed innovation; their reactions are an important factor in the extent to which the innovation is successfully implemented and must be taken into consideration by those proposing innovation.
