When you complete the course I believe you get a certificate of completion, not a certification. Let me get some more information on it.
However, for a valid certification you can take a look at these:
SAS Certified Associate: Programming Fundamentals Using SAS 9.4
This is the basic entry level certification. Shows you have fundamental knowledge.
SAS Certified Specialist: Base Programming Using SAS 9.4
This one is one level up from the Programming Fundamentals certification.
Hope that helps. Let us know if you have any other questions.
