The Adventure Academy (PF1)

From the introduction:

Whether you’re an apprentice learning the ropes of your adventuring trade or an expert researching your tome on the mysterious ruins of a lost civilization, adventure academies are an effective way to advance your adventuring career. In some lands, academies are rare and even sometimes mistrusted collections of lore and power, while in others civilizations they are where the society’s lore is preserved and passed on to future generations, handed by educated experts to an eager generation to be further analyzed and refined until it is ready to be passed on again.
