If you are Adobe Certified and facing certification expiration, you can renew your certification for two more years by taking and passing the appropriate renewal exam.
Renewal exams are shorter, lower-cost exams designed for current practitioners to renew or extend existing certifications. They are not standalone certifications, and they must be taken before your existing certification expires. Once your certification expires, you will have to take the regular certification exam to renew your certification.
These exams include information critical to understanding newer capabilities and functionality within their respective applications.
