Seven strong claims about successful school leadership revisited

In 2008 we published an article in this journal entitled Seven Strong Claims about Successful School Leadership. The article was based on a major literature review that was summarised in a paper published by the National College for School Leadership in England.  the National College paper and our subsequent article proved to be far more popular than we anticipated and both have been extensively cited over the past 10 years. This article revisits each of the seven claims, summarising what was said about each in the original publications
