World Languages Department

The World Languages Department is committed to providing a Christian education to our language students, with special attention to those most in need, so that all language students may achieve personal fulfillment in their study of the language. To provide a challenging college preparatory language study, students have a choice of three languages: French, Latin, and Spanish. Each language offers a variety of courses that will prepare them for both college and life. Students have the opportunity to develop an appreciation of linguistic, cultural and racial pluralism through courses and experiences that will help them develop as persons of compassion, faith, and intellect.
