We did not have a good experience at One World with our children given the lack of safety, care for, and oversight of children, or for the teachers that did inappropriate things. Once the Social Services investigated all of the incidents, we knew we had to leave. Our family did not have a good experience here along with many others. Highly suggest literally any other school to protect your kids.
