Novorapidboi26 makes a good point. If your daughter hasn't been going it alone then you can take advantage of the summer break and ask her what she would do when you think any checks/changes may be required (if she doesn't do her own set changes, now is a good time to start).
As a retired high school teacher, the only time I heard of parents coming in re child's medical condition was to bring in forgotten medication (not likely to happen with the pump) or the school thought the child was too ill for school.
Just make sure the school knows about your daughter's diabetes and this will be passed on to staff at the beginning of term (along with necessary information (eg Don't try to confiscate a phone/game as it will most likely be her insulin pump.)
An emergency kit should be left at the school or carried daily by your daughter. It is unlikely that she is the first diabetic pupil they've had, so don't worry.
Just one point, if you do leave an emergency kit with the school, make sure they don't stick everything in the fridge. When one of my pupils couldn't get his glucose monitor to work I noticed it was full of condensation - it turned out that it had been kept in the fridge along with the insulin!
