My old school had lockers, that's where we were expected to keep our bags and whatnot. They were about half my height, which was a pretty decent size and you could fit most things in them, downside being that those with bottom lockers had to sit/squat and half of those with top lockers had to stand on their tippytoes to reach the top shelf haha. I remember I used to keep forgetting my locker combination and they had to get maintanence staff to come and cut the lock in half, then give me a new one.
Current school has lockers, but they're pathetic tiny metal ones and they cost five bucks a year, which is silly considering nobody who has one uses it anyway.
