Are teachers allowed to restrict how many times a student is to go to the bathroom
If so why have I heard of people suing because of this very reason yet there are still so many schools continuing to follow the trend

Is this in High School? When I went through school we were expected to tend to our toiletry needs between classes. You will have similar requirements at a workplace as adults and they treated us as adults.

Nowadays, people are just looking for an opportunity to sue. If you are over 8 and can't manage your bladder I think that is really sad.

It will depend on the teacher, the school and the school district as policies will vary. There is a fine line that has to be looked at. How often is enough? How often is too much? Where do you draw the line? Does it depend on the age of the child? This is one area you will never have everyone's agreement on.

People obviously need to use the bathroom, and you can't always regulate when you might have the need. However, teachers will often have students who will ask to leave numerous times and not really be leaving to use the toilet. Sometimes they are meeting friends, sometimes they are causing trouble, sometimes they are hoping to skip out on work they don't want to do, always they are missing out on learning.

You can limit the number of times a student goes to the restroom because as other members have stated, some are just going for the sake of going. As a teacher, I suggest that if your child needs to use the restroom more frequently talk to her/his peditrician and you could easily get a note stating the medical reason behind it. However, I know my students well enough to know if they really have to go or if they just want to leave the classroom. And... yes people are "sue happy." Inmates have also sued and won because they were not served steak on a weekly basis!
