UiPath doesn’t offer training and/or certifications for individual users. For that we have the Academy.
And as you’ve surely noticed, we have added more complex courses(and there are more to come next year) for this reason precisely: to give the individual users the opportunity to learn for free. Having only onsite trainings would consume resources on UiPath side and money on user’s side, so in my opinion the Academy is sufficient.
Anyways, you can contact the sales team here if you want more details, but they will tell pretty much the same thing(with more sales “terms” ).
