Every Denodo certification is tied to a version of the Denodo Platform. The certification will expire at the end of the general support date of the version of your certification.
For example, if you are a Denodo Platform 7.0 Certified Developer, your certification expired in June 2024. And if you are a Denodo Platform 8.0 Certified Developer, your certification will expire in June 2026
For more information about Denodo Platform maintenance, see the section “Supported Platform Releases” on the Denodo Support Guide.
