6/10GreatSchools RatingParent Rating AverageWe moved to this school after several years in private school and have been extremely impressed. The teachers are very caring, engaging and responsive. The principal, Mr. Frazier, uses a book called Teach Like a Pirate which encourages teachers to bring passion to engage kids. It seems to work. While the school uses the Common Core, it doesn't seem obsessed with it and kids are learning.Parent Review10y ago - Southampton High School
