A pupil cannot be excluded for more than 45 school days in one school year.
This means they cannot have one fixed-period exclusion of 46 school days or more. They also cannot have lots of shorter fixed-period exclusions that add up to more than 45 school days.
This is true even if these exclusions have been given in different schools.
Lunchtime exclusions - where pupils are excluded from school over the lunch period because this is when their behaviour is a problem - are counted as half a day.
