Cranbrook Schools are independent day and boarding schools that provide students with a challenging and comprehensive college preparatory education. We motivate students from diverse backgrounds to strive for intellectual, creative, and physical excellence, to develop a deep appreciation for the arts and different cultures, and to employ the technological tools of our modern age. Our schools seek to instill in students a strong sense of personal and social responsibility, the ability to think critically, and the competence to communicate and contribute in an increasingly global community. Guiding Principles Cranbrook Schools comprise a college preparatory day and boarding educational institution, early childhood through 12th grade, consisting of three divisions: a lower, middle and an upper school. We are structured to recognize and respond to the developmental, cognitive and creative needs of boys and girls and are dedicated to excellence in all aspects of education.
