To take a beginning language class at CCSF, there are no required placement exams. Just enroll! (There are a few advisories for some courses, please see the college catalog for details. http://www.ccsf.edu/Catalog .)
If you have studied a language before, taking the placement advisory (optional) is one way to find out which level course is right for you. Please follow the links for each language for details.
If you place in a higher level course and complete it with a grade of B or better, you may be eligible for extra units. Again, follow the links for each language for details.
