These are the published times of the school day when the school is open for pupils.

There are usually two sessions per day – morning and afternoon, split by a lunch break. There is also usually a break mid-session, particularly during the morning.

These hours will account for a significant proportion of the directed hours.

During those sessions, teachers will have timetabled teaching time.

A teacher’s timetable should include, and have clearly marked on it, guaranteed planning, preparation and assessment (PPA) time and leadership and management time.
