The most effective professional development happens over a period of time, over several sessions and allows time for implementation and time for reflection about the thinking and ideas that it has stimulated. There are many different approaches to professional development. At the Historical Association we are continuing to develop flexible professional development opportunities to suit all budgets, needs and timescales. In this section you'll find details of all our available opportunities. This area will be regularly updated as new CPD opportunities become available, so don't forget to keep it bookmarked.
