This option is for those professionals who have previously failed the examination and need to retake the examination. Do not purchase this if you are applying for certification, or if your certification has lapsed. You must test at least once in a one-year period or your application will be closed, and you will need to apply anew to continue the certification process. Candidates retesting must wait 90 days to retest.
Questions regarding retesting can be emailed to firstname.lastname@example.org.
