Students do NOT go to the restrooms unescorted at any time.
Students go into the restroom one at a time.
There are two restrooms for boys - one near the girl's restroom and one across from Room 7.
The girl's restroom and it is located next to Room 20.
There are also unisex single bathrooms in a few locations in the building. Tell the student not to lock the door - but if they do, the lock is easily opened with a coin or other flat instrument.
A common whole-class bathroom routine is as follows: The entire class lines up along the wall opposite the bathroom. The teacher stands in the hall between the students and the bathrooms and calls on each student one-at-a-time for bathroom use.
Bathroom routine should be explicitly taught.
Students should be quiet in the halls while waiting for the restroom.
Teachers should be attending closely to their students.
