While I commend the making of this video, I don't recommend keeping the child in the school and trying to work through the problem this way. It is best for the child to remove them. If not for homeschool, to a different school. I was badly bullied for 3rd and 4th grade, simply moving me stopped the bullying and I never had a problem again, even when I had to move back for 8th grade. It broke the cycle.
Working within the system does not work in emergency situations, and bullying is an emergency situation. Pull them out of the school.
