We date the certificates with the date on which we receive the exam. This is true for both mailed and faxed exams. To change the date of a certificate, without proof (i.e. a signed certified mail receipt or a fax confirmation) that it had been received by us earlier, would jeopardize our accreditation. To ensure that your certificate has the proper date, allow at least 10 business days for your exam answer sheet to reach us via regular mail (remember we do not receive mail on Saturday or Sunday) or fax it (and print out and retain a confirmation of the successful fax transmission).
