The Association of School and College Leaders (ASCL) is a professional association and trade union for all school and college leaders. We are proud to support and represent over 21,000 school and college leaders of primary, secondary and post-16 education from across the UK.

Our members are responsible for the education of more than four million children and young people, in both the state and independent sectors. We work to shape national education policy, provide advice and support to our members and deliver first-class professional development.

We speak on behalf of members and act on behalf of children and young people.
