Cranbrook Schools is a private PK–12 educational institution located on a 319-acre (129 ha) campus in Bloomfield Hills, Michigan. It includes a co-educational elementary school, a middle school with separate schools for boys and girls, and a co-educational college-preparatory high school with boarding facilities. Cranbrook Schools is part of the Cranbrook Educational Community (CEC), which includes the Cranbrook Institute of Science, the Cranbrook Academy of Art, and Cranbrook House and Gardens. Christ Church Cranbrook is also on campus. The Cranbrook community was established by publishing mogul George Booth, who bought the site of today's Cranbrook community in 1904. Cranbrook was designated a National Historic Landmark on June 29, 1989, for its significant architecture and design. It attracts tourists from around the world.^[1][2] Approximately 40 acres (160,000 m²) of Cranbrook Schools' campus are gardens.

As of 2023, Cranbrook Schools had an endowment of $217 million, among the fifteen largest held by America's boarding schools.^[3] In addition, the Cranbrook Educational Community, of which the schools is a member, had an endowment in excess of $300 million in 2007.^[4]

As of 2021^[update] it had 1,656 students, making it Michigan's largest private school by enrollment in a single campus.^[5]

In 1915, George and Ellen Booth opened a portion of their property to the general public with the construction of a small Greek Theatre. In 1918, the Booths built the Meeting House, which became the Bloomfield Hills School, opening for local children in 1922 (grades 1–12).

Subsequently, the Booths decided to build a middle school and a college preparatory school. Cranbrook School for Boys, which began operations in 1927, was designed by world-renowned Finnish architect Eliel Saarinen. Completed in 1928, it was Saarinen's first executed architectural work in the United States.^[6] The name "Cranbrook" was chosen since Cranbrook, England was the birthplace of George Booth's father. Kingswood School Cranbrook (for girls), also designed by Saarinen, opened in 1931. Cranbrook and Kingswood enrolled students from grades 7–12. The Bloomfield Hills School became an elementary school and was renamed Brookside School Cranbrook in 1930.

Unlike the Cranbrook School for Boys, which has several buildings, the Kingswood School has only one building, which includes supporting facilities. It houses dormitories, a dining hall, an auditorium, classrooms, lounge/common areas, a bowling alley, and a ballroom. The education at Kingswood School Cranbrook was initially primarily viewed as a "finishing school". Today, Students take classes in English, History, Religion, and Art at Kingswood. The art classes available are Foundations in Design, Sculpture, Drawing, Weaving, Ceramics, Fashion Design, Painting, and Photography.

For the Booths and Saarinen, the conception and design of the Cranbrook and Kingswood schools were greatly influenced by the Arts and Crafts Movement, which began in 19th-century England.^[7]

In 1923, Booth founded an Episcopal church to serve the nascent Cranbrook community, as well as surrounding communities. He chose the firm of Goodhue Associates to design the church. Groundbreaking took place in 1925, and Christ Church Cranbrook was consecrated on September 29, 1928.^[8] Originally Cranbrook and Kingswood schools were affiliated with the Episcopal Church, but they have since secularized. However, special occasions are still celebrated at Christ Church Cranbrook.

Cranbrook School, Kingswood School, and Brookside School operated separately until 1970, when it was decided to govern them together. This was followed by the creation of the Cranbrook Educational Community. In 1985, Cranbrook and Kingswood schools were merged to create a co-educational upper school institution.

The middle school did not become co-educational; it was divided into gender-specific campuses in 1984. The Community acquired Vaughan School to house the boys' middle school. The basement of Kingswood was at one point the girls' middle school. A new Middle School building opened in 2010. For boys and girls of grades 6–8, all classes are separate. The exceptions are those for the performing arts (Symphonic Band, Orchestra).

Architecture critic Paul Goldberger of The New York Times called the Cranbrook campus "one of the greatest campuses ever created anywhere".^[9][10]

In 1985, Cranbrook School and Kingswood School were merged to create a coeducational upper school, the Cranbrook Kingswood Upper School. Classes are taught on both the original Cranbrook and Kingswood campuses.

Frequently, the school is referred to as "CK" by its students, faculty, and alumni. Cranbrook Kingswood now lays claim to 70 athletic teams; both men and women's teams earned state championship titles in hockey, tennis, lacrosse, golf and swimming. As of 2011, there were 795 students, approximately one-third of which were boarding students who live in single-sex residence halls. Cranbrook Kingswood accepts slightly fewer than half of all applicants, placing it in the most selective 25% of preparatory schools in the United States.^[11]

Several programs offered at Cranbrook have won awards and recognition. The student newspaper The Crane-Clarion has been recognized by the Columbia Scholastic Press Association and the National Scholastic Press Association.^[12] In 2009, the Upper School's student literary arts magazine, Gallimaufry, received a Gold Crown award from the Columbia Scholastic Press Association.^[13] The robotics and forensics team have also won several state and national awards. Their Model United Nations team has also been placed in the top 75 in North America as of Spring 2012.^[14]

Total enrollment at Cranbrook during 2007–08 was 1626, with 780 enrolled in the upper school, 333 in the middle schools, and 513 at the lower school Brookside. (Brookside's numbers include children enrolled in pre-kindergarten, junior kindergarten, and kindergarten at the Vlasic Early Childhood Center, which opened in 1996.)^[15] Approximately 11% of Cranbrook Kingswood's students are international students. Traditionally, Cranbrook School also has an exchange program with Cranbrook School, Kent, a boarding school in Cranbrook, Kent, England in honor of George Booth's heritage.
