I do not recommend this school. The supervision of students is extremely deficient, and there is no assistance from the principal (or teachers) for problems with bullying. Much is kept from parents, and children are encouraged by the school to not report, and their concerns are dismissed or minimized. Not a healthy environment for children who are not able to fend for themselves.
