don't know if you still need the help but... we start elementary school when we're five. it's kindergarten and then 1st-5th grade (sometimes it's 6th but usually it only goes to 5th)

the middle school starts (new school transition). it's 6th-8th grade. (ages 11-13)

the high school (new school transition). it's 9th-12th grade (ages 14-18).

that's the usual school timeline but alternatively there are also secondary schools that are like middle schools and high schools combined in one building. hope this helps
