‘Teacher Coaches’ are in a great position to shine a light on existing successes and spread that light across the school. School leaders can do this of course, but staff are more open to their colleagues suggesting and driving improvement. The coaches can become roles models of the best kind: undertaking research; tweaking the school environment; providing evidence of successful pedagogy; supporting underperforming colleagues; embodying a growth mindset and being open to adapting their practice to improve – in effect, becoming leading lights to drive change.
