Cranbrook P.M., a continuing education and outreach program, was founded in 1973 by the Cranbrook School Mother’s Council. The program, which became defunct by the mid-1990s offered a series of evening classes, lectures, seminars, workshops, tours, etc. focusing on the arts, languages, math, music, sports, and the sciences. The collection primarily focuses on the program's curricula, however there is a small amount of material associated with its administrative functions.
