Kindergarten students participate in weekly swim class at the YMCA Sterling Center. Weather permitting, the group walks together or they travel using Harborlight transportation. At the first class, each child is assessed for swimming ability and placed in an appropriate developmental group to ensure safe, skill-building lessons. This experience also serves as a first introduction to the Going Out program, a hallmark of Montessori elementary education, where children learn to extend their classroom into the wider community and build independence through purposeful outings.
