GreatSchools Rating
Parent Rating Average
This is a small school where everyone really knows your kid. The community is welcoming and diverse, and it genuinely feels like parents, teachers, and students all have a voice. The teachers and staff truly care, and it shows. My kids have really enjoyed art, music, and LEGO classes, as well as great assemblies and field trips. Outdoor Ed is probably the student favorite. Because the student body is diverse, achievement levels vary, but teachers do teach students at their level through small reading and math groups. The recent outdoor renovation—new playground, turf, and an outdoor classroom—has been an awesome upgrade and is well loved by the students and neighborhood.
