The school story is a fiction genre centering on older pre-adolescent and adolescent school life, at its most popular in the first half of the twentieth century. While examples do exist in other countries, it is most commonly set in English boarding schools and mostly written in girls' and boys' subgenres, reflecting the single-sex education typical until the 1950s. It focuses largely on friendship, honor and loyalty between pupils. Plots involving sports events, bullies, secrets, rivalry and bravery are often used to shape the school story.
