As a Head of PE I would say the most important things I would value in a prospective employee are: 1) The ability to teach a range of activities to a range of ages. The ability to pick up new skills quickly. 2) Excellent organisational skills 3) A passion for the subject which they could convince me they could put across to children and inspire them to want to do physical activity 4) Initiatiative (ie not having to be spoon fed and constantly monitored for everything) and innovative thinking. 5) Tact and diplomacy/emotional intelligence/ability to maintain good relationships across the board ( a quiet confidence is also nice). 6) A willingness to give time to their job. Anything else is a bonus.
