Claudine at School (French: Claudine à l'école) is a 1900 novel by the French writer Colette. The narrative recounts the final year of secondary school of 15-year-old Claudine, her brazen confrontations with her headmistress, Mlle Sergent, and her fellow students. It was Colette's first published novel, originally attributed to her first husband, the writer Willy. The work is assumed to be highly autobiographical, and includes lyrical descriptions of the Burgundian countryside, where Colette grew up.
