HCL Domino (Lotus Notes) Professional Certifications are BACK!
Lotus Notes certifications were first started with R3 as I recall. There was a test series for developers and for administrators. In later versions they added a harder test for Principal level of certification. The title was Certified Lotus Professional Developer and Certified Lotus Professional Administrator ( Some of us dedicated professionals earned the distinction of Dual Principal Certified Lotus Professional.
Certification exams were abandoned by IBM after R9, but HCL has had certification exams on their list of action items since they acquired the Lotus portfolio of software, along with other education materials to further professional growth and expertise in their software. It looks like the first version of testing will come with V12. There will be the usual admin and dev tracks, there are plans for Security and Volt MX as well. You can find the slide deck that was presented by HCL at the 2022 Engage User Group Conference.
