In 1993, PSU comprehensively reformed its undergraduate curriculum with a new curriculum called University Studies that is unique to the institution. The curriculum was conceived to address issues of credit distribution which required students in upper-level courses to enroll in classes outside of their majors.[36] In a 1993 summary report on the reform, it was stated that the University Studies sought to incorporate "'across-the-curriculum' themes including writing, diversity and multiculturalism, ethics, and global studies," as well as form a foundation that "includes the capacity and the propensity to engage in inquiry and critical thinking, to use various forms of communication for learning and expression, to gain an awareness of the broader human experience and its environment, and appreciate the responsibilities of persons to themselves, to each other, and to community."[36]
