You do not need a reason and you do not need permission. You do need to not turn up during a period — they will be teaching.
Walk inEvery teacher keeps one free period a week for parents, listed against their name above. Come then and you'll get twenty unhurried minutes.
After the last bell4:15 to 5:30, most days. Teachers running the doubt hour will be in their room anyway.
Through the officeLeave a message and the teacher calls back within a working day. If they don't, tell the principal — that's not a complaint, it's information.
Parents' eveningTwice a term, Saturday mornings. Report cards are handed over in person, never sent home in a bag.
What we do firstIf a child is slipping, the class teacher calls you before the marks reach you. That call is the job, not a courtesy.
What we don't doNo WhatsApp groups for academics. Nothing important is decided in one.
