When you successfully complete any CCO Course (not a Blitz), the system will generate a Certificate of Completion for you at the end of the course. This certificate confirms that you finished the training program.
A Certificate of Completion is not the same as a professional certification. Many CCO courses are designed to prepare you for various certification exams, but the certification credential itself is awarded by the external certifying organization after you apply for and pass their exam.
To see what your specific course includes and which certification exam it helps you prepare for, visit the sales / info page for that course at cco.us.
Note: Blitzes are review products and do not generate a Certificate of Completion. If you need help finding the right course or documentation, contact the Help Desk.
