I think from 1.0 Grid Main quest line, there was someone look after them like the Carpenter Guild master. They just play and play all day...

but there is no physical school I think, that's why they need to join specific guild to learn stuffs after lv10 ^^::
I think at least one of them will be terrified about the elementals (that annoying trouble-maker's sister at least, she saw more stuffs...) @@:

But, you can go ask Professor Moose @ lore page. Bring him some cookies, and he'll tell you lots stories.
