It could be trivial to do an express “recertification” by recording a video of your workspace once in a while, after you’ve done the full certification.
I think we all need constant monitoring and certification that we're not shitting our pants. Because, you know, shitting one's pants is bad, so we totally need some patroling to save people from this. Can we count as a civilized society while we let pants-shitting happen to our citizens?
