There’s a common assumption that in-house CPD (continuing professional development) is the way forward in schools. After years of poorly presented and ultimately fruitless courses on subjects chosen by others, like rootless flowers, it’s probably safe to say that very often the best development opportunities come for the colleagues we work alongside every day. And while swallowing that for some time, I began to realise I was waiting for someone else to do it for me. I’m getting on a bit. I couldn’t wait any longer.
