The use of coaching in schools is a method that can be used to support staff to develop their practice through setting goals and working towards them. Goals are more likely to be followed if they are led by the coachee. Coaching should help a staff member to identify their own strengths and areas for development and build targets around them. There may be an element of passing on knowledge and experience but a large part of coaching is based on self reflection with support.

There is evidence to say that coaching in education can lead to increased teacher wellbeing, reduced stress and increased resilience skills. It can also lead to improve practice, improved leadership and performance management skills. Coaching is a relatively new area so research is limited and so some individuals may prefer different methods of support.
