The easiest way to introduce Tree is by a staff development event. Experienced trainers can provide a training forum tailored to particular needs either for individual or clusters of schools.
The important thing about Tree is that it is not a rigid programme to be followed slavishly this means that the training programme focuses on establishing a consensus around the core qualities and attributes and exploring the philosophy behind them and the programme as a whole. Once staff are confident with the philosophy and general principles of using the qualities and attributes ways can be explored in which these are incorporated into classroom practices and routines, the software can be demonstrated and examples from where Tree has been introduced can be discussed.
