Do you have lockers at your boarding school? Is it like a locker room or are there just lockers in the hallways? If you don’t have a locker where do you keep your supplies? A backpack?
No lockers for boarders. Backpack/dorm room.
For sports, but not for the regular day.
and at some schools, for musical instruments.
Day students have a locker boarding students carry what they need. Gym has lockers available as does music building.
