All youth who have not yet completed a GED or high school diploma are required to attend school. Oak Creek has a school on site to help students earn high school and college credits.
Three Lakes High School has a similar structure to other public schools, including:
- A principal, certified teachers, and other support staff.
- A fully digital campus with computers and laptops available for all students.
- A five-period school day.
- Educational goals that require them to work toward earning a high school diploma or GED.
If they have already earned their high school diploma, students can take college courses online or in person at Oak Creek. These courses are also available as dual high school/college credit courses through partnerships with Linn-Benton and Portland community colleges.
