SOC-12
Two characters, both Medical-3, one Edu 4, one Edu D. Both have the requisite skills and abilities to be called physicians, but one is more learned than the other in areas not otherwise represented by the characters' skills.What meaning/purpose does Edu now have?
The Edu 4 doctor went to a top medical school and struggled mightily to achieve Medical-3, leaving little time or interest for pursuing wider knowledge, learning only enough to pass exams with the minimum score required and retaining little of what was studied that didn't pertain to becoming a doctor. Succeeding in medical school required a laser-like focus that left little to invest in other pursuits.
The Edu D doctor studied at a third-tier medical school on a backwater world but retained much of what she studied. She is a voracious reader with wide ranging interests. She met the minimum requirements to become a physician, but has a command over a broader range of topics than her Edu 4 peer.
Note that their skill as doctors is exactly the same. It is their edcuation independent of their skills that varies, as represented by the Edu score.
This is why a discrete connection between Education and academic achievement is a complete waste of time. The Edu score is there to represent what the character knows outside of the abilities expressly represented by skills, and it is a relative scale for comparing characters. It is also a tool for playing the game, providing a threshold for certain rolls or an attribute against which to test for success.
