Tustin Adult School operates on the philosophy allowing students to begin as soon as possible by way of using Open-Enrollment. Open-enrollment allows students to start classes and programs without waiting until the next session/semester.

Some programs require pre-assessment(s) to identify the appropriate course level a student should begin, as well as, a meeting with the guidance counselor. In addition, there are occasionally exceptions to the open-enrollment policy. These exceptions will be advertised are generally in place to avoid discouraging student success.

Please view the Programs page for important details of our classes and resources offered. You are also welcome to contact the office for further assistance, schedule an appointment to meet with the guidance counselor, etc. by calling (714) 730-7395.
