There are four stages of response, depending on the level of virus cases in the area:
Tier 1: All pupils attend as normal.
Tier 2: Secondary schools and colleges move to rotas, with students alternating a fortnight attending and a fortnight at home. Primary schools remain open to all.
Tier 3: Most secondary pupils learn from home as secondary schools and colleges are only open to vulnerable children, the children of key workers and selected year groups.
Tier 4: All schools switch to remote learning, except for vulnerable children and the children of key workers, and students at alternative provision and special schools.
If a child at the school becomes infected, local health protection teams will advise the school on what to do next.
