Bedales School is a public school in the village of Steep, near the market town of Petersfield in Hampshire, England. It was founded in 1893 by Amy Badley and John Haden Badley in reaction to the limitations of conventional Victorian schools and has been co-educational since 1898.

Mixed-sex education, also known as mixed-gender education, co-education, or coeducation, is a system of education where males and females are educated together. Whereas single-sex education was more common up to the 19th century, mixed-sex education has since become standard in many cultures, particularly in western countries. Single-sex education remains prevalent in many Muslim countries. The relative merits of both systems have been the subject of debate.
