The Classroom Building at Oklahoma State University is a central facility designed to support the academic needs of students across various disciplines. It was completed and opened for classes in 1952. Built at an estimated cost of $850,000, the building included a basement and four stories and was designed to duplicate its companion to the north, the Engineering Building (now Engineering South). The Classroom Building houses multiple classrooms, computer labs and walk-up support services, including ID services. It is also home to the LASSO Tutoring Center, which offers free one-on-one tutoring, academic success coaching and supplemental instruction to help students excel in their courses. The Classroom Building is an essential resource for fostering student success and providing a conducive learning environment on the OSU campus.
