On the waiver form, I see a line that reads: "8. Certification of Qualifying Criteria: I certify that I meet at least one of the following criteria and am therefore a qualifying provider (Check and provide copies of documentation for all that apply):"
The documentation the question is referring to is the DATA 2000 Training Certificate. You do not need a certificate for completing your training because we send the names of all people completing the training within around one week of completion. Most providers should complete the online version of the waiver form, and if you do, it is not necessary that you mail or fax a copy of your certificate. CSAT obtains confirmation of your training from us.
