Yes. Certified professionals have to maintain ‘Active‘ status of their certifications by renewing it every three years and prior to its expiry date. Once the certification passes its expiry date, it will show as ”Suspended” in the Certification Registry, and this status remains for 3 months. This would be the last chance to renew the certification without writing the exam again. If the 3 month period elapses, the certification becomes “Expired” and you must write the exam again to earn the certification.
