The school employs a curriculum based on four foundational concepts: community, diversity, Montessori and academic excellence.

[1] In recent years, Caedmon students have moved on to a variety of schools including: Allen-Stevenson, Brearley, Browning, Chapin, Collegiate, Columbia Prep, Dalton, Horace Mann, Nightingale-Bamford and Spence.

[4] By the fall of 1961, a group of ten families in New York City who had attended Rambusch's talks began planning a school.

The families that remained were to become Caedmon's founding trustees: Marilou and William Doyle; Elizabeth and Vincent Connelly; Joyce and Daniel Flynn; Nellie and Thomas Mahoney; and Robert Hurley.

[6] Rambusch who had been instrumental in the reintroduction of Montessori schools in the US by adapting the program to better fit American educational culture, had a strong influence on the development of Caedmon.

In 2002, the National Association of Independent Schools' Leading Edge Recognition program recognized Caedmon with its Curriculum Innovation award.

Caedmon's curriculum utilizes an inspired Montessori approach and reflects the highest standards of the most competitive independent schools.

In the Elementary Program, students have exposure to the major curricular areas: language arts (i.e., reading, writing, spelling, handwriting), math and social studies.

Caedmon's curriculum is expanded and enriched by regular instruction in art, computer, foreign language (Spanish and Latin), library, music, violin, science, and physical education (including yoga), which are taught by specialists outside the classroom.
