How about offering Vulkan Certification Programs?

Hello, I am studying Vulkan so hard but it is difficult to master it

How about this idea below ?

Khronos offers Vulkan Certification Programs, periodically

For example
Khronos opens Vulkan tutoring online programs for some amount of fee, twice a year (for example)
It teaches Vulkan to people and answers their questions
It offers tests periodically to applicant for some fee. For those who pass it, Khronos awards certificates
Of course, Khronos should publish studying materials intensively in Vulkan and modern GPU and compute programming

( However, in South Korea, Vulkan is not famous. So here there are only few programmers wanting such Certificates )
