John Woolman School (JWS) was a private boarding Quaker high school founded in 1963 in Nevada City, California. It operated full-time until 2001, when it closed because of financial difficulties. Since then, the facility has been adapted for use for short-term educational programs for teens and adults, as well as summer residencies. The centerpiece is the Woolman Semester, a single-semester residential program that provides an experiential education in the principles of peace, social justice and sustainability for high school juniors, seniors and post-graduates (gap year).
