[1] The school is guided by the educational philosophy of Cornelia Connelly, the founder of the Society of the Holy Child Jesus, and her dedication to developing "young women of conscience and action".

The school enrolls students from nearly 70 communities in Westchester, Fairfield, Putnam, New York and Bronx counties and offers programs in the humanities, global & religious studies, science & technology, engineering & architecture, arts & athletics, as well as field-based and service-learning programs.

The school's 20-acre (8.1 ha) campus in Rye contains a Tudor Revival mansion dating back to 1930, as well as recently constructed academic and extracurricular facilities.

In 2012, the school launched the Generoso Pope Italian Cultural Studies Program, a two-year program of language, history, research, and study of Italian culture that culminates in a two-week summer trip to Italy.

In 2018, the school received another grant from the Edward E. Ford Foundation to create the Leadership Institute in Finance, a two-year, college-level seminar course that covers financial literacy and business ethics.
