While our classes are limited to a maximum of 15 students, several are actually smaller, which means more undivided teacher attention for your child. Fewer students means that more material can be covered, while leaving time for in-depth class discussions, which further learning and understanding by allowing children to explore their own ideas.

Small groups enable peer-to-peer learning, which empowers children to take ownership of their education and builds self-esteem.

Small classes also mean that the necessary review of new materials happens largely in the classroom, reducing sharply the amount of homework assigned that would otherwise intrude on their outside enrichment activities and important imaginative free play.

Small classes also mean higher intellectual achievement and allow for an advanced curriculum. According to a 1999 study by Mitchell & Mitchell, smaller classes in grades K through third grade improve student achievement in reading and math.
