What kind of leader are you, and is your leadership style truly effective? After looking the UK’s performance in the 2012 Programme for International Student Assessment (PISA) study and comparing it to other countries, Dr Alex Hill and his research team decided to find an answer to the question: Why does the UK still lag behind its peers, despite investing more than them? In the process of this research, the team studied over 400 leaders from schools in the UK – the results of which have been published in the Harvard Business Review. In doing so, the team identified that there are five different types of leaders: surgeons, soldiers, accountants, philosophers and architects. Dr Alex Hill, Co-Founder and Director of The Centre for High Performance, joined me on the line from the UK, to discuss why there are five different types of leaders, but only one type that is truly effective.
