When a child gets expelled from school it means that your child is no longer able to attend that school anymore.
Being expelled from school doesn't mean the child doesn't have to go to school anymore but instead you must enroll the child into another school in another school district or another school near the area you live if they will accept the child in their school.
Before a child actually does get expelled from school they will be suspended for around 10 days and then if the student does something wrong again then they will be expelled from school.
So it's never a good thing when a child gets expelled from school and you'll have to find another school for the child or home school the child.
Or you may have to move to another town or state to allow the child to be enrolled into school again.
