Purpose of Advisory Advisory classes meet once per week on Wednesday. When possible, students will stay with their advisory teacher over the course of their four years at Vista. Vista del Lago High School’s advisory program has three purposes: 1. Create positive and caring relationships among staff and students, which promotes an emotionally and physically safe environment for all students. 2. A support system to promote high levels of learning for all students. 3. School wide exposure to relevant and important issues, which include college and career readiness as well as social and emotional growth.
