From what you have read so far, you can see that the landscape of schools in this country has changed greatly over the last decade. Many headteachers are working beyond their own school, taking on responsibility for leading more than one school or providing support for failing schools. This obviously has implications for you as a senior leader.
You may find yourself in the position of running the school on a day-to-day basis (fulfilling the role of a headteacher). You will not be able to fulfil all the responsibilities of your senior leadership role on your own and will need to rely increasingly on the support of colleagues from within your own school, as well as on colleagues from across the partnership or network of schools or other organisations with which you work. In effect, this is distributed leadership.
