Phone the school or college and ask for the name of the receptionist. Try to book an appointment to see a teacher, tutor, head of year or even the head or principal. Keep a note of when you phoned and a record of what was said and by whom. Turn up at the school or college demanding to see an individual. Remember teachers are busy and may be unavailable.
Free time is scarce and precious.
Better to arrange an appointment when you are calm and have planned what you are going to say. Find out about the school or college procedures. This is easily done when your child starts at a school or college. Most will let you have a copy of the relevant section. Expect your child to know how a school operates.
