What's the pinnacle of dog training?

I've been following the Jordan Shelley story and have seen him ask you what courses he should go on. I'd love to be the best dog trainer I can be, what are the best qualifications to take? Are there any that can be done remotely as I have kids and will need to study part time.
Do I need any qualifications to study? I want to do this properly.
If money and time was no object, what would be the Harvard or Oxford and Cambridge of dog training and why?
