As of October 2022 you are considered eligible to sit for the Exam for eight years from the date you completed your CPME approved PMSR-36 or PMSR/RRA-36 residency. If you do not attempt the examination in that time period you are no longer eligible. If you attempt to take the Certification Exam during this eight year period and fail, your eligibility period is extended out for an additional 5 years. The maximum eligibility range is therefore 13 years.
