There are two types of exclusion:
Fixed period exclusion
This is where a child is excluded from School for a certain number of days. This can be up to 45 days in any one academic year.
This is where a child is not able to return to the school from which s/he is excluded.
Headteachers and School Governors follow detailed guidance laid down by the Department for Education (DFE) (see 'Downloads' section below).
