Supply teacher vs cover supervisor

In short

A supply teacher is engaged to teach. A cover supervisor supervises a class working on tasks that have already been set by the class teacher. The distinction is about the nature of the role, not seniority.

	Supply teacher	Cover supervisor
Core role	Teaching	Supervising pupils working on pre-set tasks
Plans the lesson?	Often, especially on longer placements	No – work is set by the class teacher
Typical use	Absence, vacancies, maternity, long-term gaps	Short, planned or unplanned absence
Qualified teacher status	Expected for teaching posts in maintained schools	Not a teaching role

Arrangements vary. Job titles and duties are not standardised across schools, and some roles blur the line in practice. Treat this as the general distinction rather than a universal rule, and check what a specific post actually involves.
