School Overview
Century Junior/Senior High School, located in Ullin, Illinois, serves as a combined secondary education facility for the surrounding community. As part of the Century Community Unit School District 100, the school is designed to bridge the transition from middle school through high school, typically housing students from grades 7 through 12. Its rural setting reflects the focus of many small-town Illinois school districts, where the institution often acts as a central hub for student development, extracurricular activities, and community engagement.

The school operates with a commitment to providing a comprehensive academic curriculum while maintaining the smaller class sizes and personalized attention often found in regional school districts. By serving both junior and senior high students under one roof, Century facilitates a continuous educational environment that allows for stronger mentorship opportunities between older and younger students, as well as a streamlined approach to faculty collaboration and student support services.
