Caedmon is a unique education. Quite simply, we do what is good for children. located on a quiet, residential street on the Upper East Side of Manhattan. an ongoing school, nursery through 5th grades. Our program combines high academic standards, an emphasis on the arts, and a strong focus on social development. deliberately small in size. Our enrollment is 210 children between the ages of 2.9 and 10 years. The average class size is 16-18 children with two teachers. a Modified Montessori school. Our program develops a love for the process of learning by sustaining the natural motivation with which all children are born. ethnically, racially, culturally, economically, and intellectually diverse. Diversity is a cornerstone of our philosophy. a school with a large international population. 25% of our enrollment comes to us from as many as 30 different countries. a community of enthusiastically involved families, offering a warm, congenial atmosphere and a very active Parents Auxiliary.
