How It Works
How It Works
Catalina Online Learning Experience serves students in grades 6–12 and gives access to a complete curriculum. We offer scheduling flexibility, provide online access to coursework, and allow students to work at their own pace toward deadlines.
How it works, step-by-step:
1. Registration instructions will be available for existing students after July 31st through APEX.
2. When school begins, log in and work on your courses from an Internet-connected computer. Assignments, tests and quizzes are online 24/7.
3. Succeed at your own pace. Our curriculum is designed to suit various learning styles and skill levels. Meet due dates while working at your own speed.
4. Get real help when you need it. For each course, you are assigned an experienced, certified teacher who is accessible via virtual whiteboard, phone, email, or instant message (IM). You will also be assigned an Academic Advisor to keep on track.
5. Earn a diploma, or have the credits transferred to your traditional school. Upon completion of all required credits, your diploma will be issued by the Tucson Unified School District.
