In-N-Out Burger, renowned for its burgers, operates its own training facility called In-N-Out University near its original Baldwin Park, California location. Established in 1984, the university focuses on preparing employees for management roles by teaching restaurant operations, cleanliness standards, and customer service, rather than offering academic degrees. The program is exclusive to internal employees or management applicants, emphasizing the company's commitment to internal promotion and leadership development.

Founded in 1948 by Harry and Esther Snyder, In-N-Out has grown from a single drive-thru to over 400 locations across multiple states. The company’s emphasis on structured training has been a core part of its expansion strategy, with origins dating back to the 1970s under the leadership of Rich Snyder. The Baldwin Park site features a retraced model of the original restaurant and a company store, but the university remains closed to the public. This focus on employee development mirrors industry practices, with chains like McDonald's operating similar programs such as Hamburger University.
