The office of the chancellor of the California Community College has announced that its review of two-tiered tuition at community colleges in the state has found that the practice would be illegal. The office has been studying the issue since Santa Monica College announced a plan -- since abandoned -- to charge more for some high-demand courses. The chancellor's office consulted with the state attorney general's office on the issue, but a spokeswoman for the chancellor's office said that no formal opinion was requested or provided. But she said that, based on the review and the consultations, the chancellor's office is "comfortable" feeling that two-tiered tuition "is not permissible and is therefore illegal" under California's education code.
