Does the final certification state that the course was taken "online"?
The Six Sigma Certificate and the Certificate of Project Completion (if applicable) are both clearly issued by the Aveta Institute. Although the certificate does not state "Six Sigma Online" or imply that the training program has occurred online, these certificates do footnote a "firstname.lastname@example.org" that is used for employer verification (which can be excluded per request).
Please keep in mind that in today's business environment online programs are very commonplace to many organizations. Again, we supply certification to many of the largest companies throughout the world.
