Advanced Skills Teacher is a role in a maintained school in England and Wales. Advanced Skills Teachers are judged through external assessment against a range of criteria to demonstrate excellent classroom teaching practice. They are employed in Advanced Skills Teacher posts in roles which include an element of work dedicated to supporting teaching colleagues in their own schools, and other schools in the area, to improve their own practice. The role was introduced in 1998 to reward excellent teachers who chose to stay working in classrooms, rather than following other routes to promotion through leadership.
