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.  Tustin Adult School's Open-Enrollment is for the first six weeks after a semester has started for fall and spring.   For Summer School, the Open-Enrollment period is the first week of the session.  

All students enrolling must be at least 18 years old at the time of enrollment.   

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.
