Council For The Indian School Certificate Examinations [CISCE] — Not allowing kids to go to washroom

Address:

Fatima school, Tajopur, Mau (U. P.) - 275101

My nephew studies in fatima school, Mau (U. P). Their teachers doesn't allow them to go to washroom. One studies in 3rd standard and other studies in 6th. We tried to escalate this problem to principal for the resolution but to my surprise, my mother was advised by principal to change the school of kids if we have any problem with the functioning of the school. Kindly help what can be done to help kids.
