In Western Australia, primary school ends at Year 7, the year kids turn 12. Then Year 8 starts the year kids turn 13 and that is high school. It ends at Year 12 although people can leave after Year 10 and get a job or go to TAFE (Tertiary and Further Eduacation) Most people who do Year 12 and exams end up going to university.
I thought your daughter would be going to high school, Callaway.
