Computer classes are held regularly in a computer lab. In addition, each classroom has two computers. Projects are often inspired by classroom activities. Chapin's Middle School builds on the strong foundation established in the Lower School. The Middle School teaches specific organizational systems and structures which girls may personalize as they get older.
Teachers also serve as academic and extracurricular advisors.
Including Class Four in the Middle School gives younger children the advantage of a transitional year between the contained classroom of the elementary years and the departmental approach of the traditional Middle School program. Additionally, students in Class Seven have a wide range of leadership opportunities, so that girls can take responsibility at a time crucial in preadolescent development. The age-appropriate curriculum stresses classical disciplines of language, literature, mathematics, history and science. This program is enriched by classes in the arts, technology and physical education. Girls become fluent in self-expression through frequent opportunities in oral and written communication.
