Students do not have to be completing the entire IB path to participate in IB. Students can earn the full IB Diploma, which is the most rigorous IB option. Students can also earn IB Certificates by completing an IB class and passing the test. Students can also just take IB classes for their own learning and enjoyment.

Students who do not want to pursue the full IB diploma can still take IB classes and the tests to earn IB certificates. This is similar to taking an AP test, where you can take one class/test individually, with the option, but not the expectation, of taking others.
Even if your student doesn't enroll in the IB program, they may still take IB classes. The classes are open to all students and often there are a variety of students in each IB class. Students may choose to take the IB exam for a certificate, or be in the class without end-of-year testing.
