7/10GreatSchools RatingParent Rating AverageToxic environment led by principal that cares more about her position than the students. The principal gaslit us about federal law and procedures regarding IEP, which was frustrating and we only found out after consulting an advocate and lawyer. The school district will try its best not to provide services and accommodations to special needs kids. Teachers are rude and uncaring, causing trauma to very young children who cannot advocate for themselves. We had to transfer after multiple incidents with the teacher and staff. Until they find new principal and teachers, do not trust this school with your children.Parent Review2y ago
