The student activities program at Vianney High School provides an excellent opportunity for a student to fulfill his need for involvement and success in activities other than regular classroom instruction. Experiences are designed to help meet the leisure, recreational, social, and emotional interests and needs of the student. These experiences also provide opportunities for self-directed specialization in areas of the curriculum of particular interest to the student. Students are encouraged to become an integral part of at least one co-curricular activity. For general information about the activities available, peruse the list below, listen to the daily bulletin or get information from the moderator of the activity.
