Unity Learn is an official platform that provides 6 free long-term courses called “Pathways” with verification on Credly. I’ve completed 1.5 out of 6 so far, so there’s still room to grow 
in terms of certifications…
The newest 12-week pathway is called “Game Development”, and it’s designed for Unity 6.3 LTS, which is currently recommended for production.
It can help you prepare for the paid Unity Certified Associate exam.
