Beloit Summer Blocks are three-week intensive courses offered in a block format during summer, either on- or off-campus (including international Blocks courses).

Blocks are designed to allow students and faculty to explore a topic deeply without the demands of multiple classes and other commitments that occur during a regular semester. Beloit College students and visiting undergraduates concentrate on one course taught by Beloit faculty and earn 1 unit of credit. Blocks courses may satisfy one of the five domains (breadth requirements).
