Any kind of performance management would be a good start. Every year, as PM reviews loom on the horizon I review my own performance, devise a list of things I need to improve and what training would best suit. Invariably, come Inset time, the whole teaching staff are sat in the hall and told how best to manage behaviour (by making lessons interesting) or mark books(again). Can't help thinking it's a real waste of my training entitlement. For sure, I'm not the only one at my school who feels this way.
