Presbyterian Christian School (PCS) is a private Christian school in Hattiesburg, Mississippi. It serves preschool through grade 12. Grades K5-6 attend one campus, while 7-12 attend an adjacent campus. The historian Joseph Crespino has noted that, unlike many other private schools in Mississippi, PCS was established after school desegregation began and enrolled minority students within a few years of its founding. The schools current minority attendance remains low, with a C rating in diversity.
