School corporal punishment is the deliberate infliction of physical pain or discomfort and psychological humiliation as a response to undesired behavior by a student or group of students. The term corporal punishment derives from the Latin word for "the body", corpus. In schools it often involves striking the student directly across the buttocks or palms of their hands with a tool such as a rattan cane, wooden paddle, slipper, leather strap or wooden yardstick. Less commonly, it could also include spanking or smacking the student with the open hand, especially at the kindergarten, primary school, or other more junior levels.
