Just curious. I know there is a set number of days teaching for state schools - 190 a year. What about hours?
Secondary School A, B and C and the 3 main ones children on my estate go to. C are noticeably at school a few hours less a week than A and B, last to get on bus and first back.
A does 8.50-3.45 (one finish at 2.30)
B does 8.55-3.25 (one finish 2.15)
C does 8.45-3 (one finish at 2)
Two are an academy, one a local authority school.
