GreatSchools Rating
Parent Rating Average
My 5th grade year at this school was extremely disappointing. Bullying was a frequent issue, and despite teachers and staff being aware of what was happening, little to no action was taken to address it. Student safety and mental well-being did not seem to be a priority, and many concerns were ignored rather than handled appropriately. What was most concerning was the lack of communication with parents. Serious issues affecting students were not adequately reported to families, leaving parents unaware of situations that impacted their children’s safety and well-being. A school has a responsibility to protect students and keep parents informed, and in my experience, it failed to do either effectively. WOULD NOT recommend your child to attend this school.
