Most traits have threshold higher than 1. This means that putting a person into academy MIGHT help him getting a few points toward a trait without actually gaining full level of it to this fact becoming visible. However it Might prove beneficial later on in his life as other events push him over the threshold of that trait more easily than if was missing the few invisible points he got back then in the academy.
A lot also depends on other proclivites of the character. His ethnicity and intelligence play a big role in how likely is he to benefit from academic studies.
And in the end it is statistics - as with all traits, the random-number generator has the final unpredictable say in this.
