FWIW, I think that Equestria uses an apprenticeship system. Once a pony's special talent is identified, they are apprenticed to a senior pony with the same talent who then teaches them the tricks of the trade.

It's possible that Nursery Rhyme is one of the adult medical ponies' apprentice/trainee.
