Baka and Test , also known as Baka and Test: Summon the Beasts, is a Japanese light novel series written by Kenji Inoue with illustrations by Yui Haga. The series revolves around Akihisa Yoshii, the titular baka (idiot) and his friends at Fumizuki Academy, a school where students are sorted into classes based on their entrance exam test grades. The top classes receive better classroom equipment and benefits, while the bottom classes receive very little. Class F, the lowest class in the school, are angered by this injustice and vow to fight the higher-level classes for better equipment and respect. Baka and Test was published by Enterbrain, with a total of 18 novels published from January 2007 to March 2015 under its Famitsu Bunko imprint.

Baka means "fool", or "foolish" and is the most frequently used pejorative term in the Japanese language. The word baka has a long history, an uncertain etymology, and linguistic complexities.
