Is there any difference between taking a certification exam at an SAP Education organization center and taking one at Pearson VUE?

No. Certification exams are the same no matter where you take them. SAP has partnered with Pearson VUE to provide our customers with the greatest possible number of exam locations. You can take certification exams at SAP Education organization centers as well as at any of the 4,500 Pearson VUE centers worldwide.
