Looking for Top Sourcing Training/Certification Programs

I’m searching for the best sourcing training or certification options for a small team with diverse experience levels.

A couple of years ago, I completed the SourceCon Academy (at a previous company), and I found it to be excellent. Our Talent Acquisition leader has suggested AIRS, but I haven’t heard much about it in the last decade.

I’d love to hear your thoughts! Any recommendations or insights would be greatly appreciated!
