Outstanding school. Teachers and staff as a whole are amazing and clearly love their profession. They put the students first, which is a refreshing change from what we experienced from the SAU16 middle school. We had concerns initially about a charter school as our child ranks on the upper end educationally and intellectually. We weren't sure if he'd be challenged enough but we have found the project based curriculum is so much more engaging then the standard core curriculum that we couldn't be happier with our decision to switch from public schools. The smaller size of the school makes for a much more community feel and great interaction with the student body and staff overall. Can't recommend this school enough! Close Quote

My two sons attend GBeCS and they love it! The small class size allows teachers to be able to reach students with varying learning styles. Every adult in the building is caring, embracing each students individuality which in turn teaches students respect. Close Quote
