Certificate of Achievement Requirements

The Certificate of Achievement is a state-approved career program that requires a minimum of eight units and is designed to prepare the graduate to enter a particular field of employment.  In order to be awarded a certificate, students are required to obtain a grade of “C” or better in all program-required courses. Grades of “CR” or “P” will be accepted whereas “CR” or “P” meets the equivalency of a “C” or better.  At least 3 units in an advanced course from the certificate must be completed at OCC at the department’s discretion.  Certificates of Achievement are not automatically awarded.  A petition must be filed in Enrollment Services or online at the beginning of the semester in which the student will be completing their final requirements.  The petitioning periods are listed in the Graduation Requirements section of this catalog.  Check with a counselor to determine the requirements for completion.
