Having just returned from the 15th International Conference on Thinking (ICOT) in Belfast, I'm minded to recommend a few conferences coming up in the next 18 months or so:

Sustainable Success in School Development in Varberg, Sweden, 31 Oct - 3 Nov 2011

Visible Learning & Formative Assessment, London 7th Nov, Manchester 9th Nov, 2011

The International Congress on School Effectiveness and Improvement, in Malmö, Sweden, 5th to 8th January 2013

16th ICOT in Wellington, NZ, 21st to 25th January 2013

I plan to be at them all, so I hope to see you there!
