Clarification on Talents

By Shakespearian_Soldier, in Grimm RPG

Here's hoping these forums are frequented enough that I'll get an answer to my question:

Each time a kid graduates to a new grade level, he/she gains a new Talent - which they take is pretty open, provided the kid meets the requisites; but some Talents have requisites that require a kid to be a certain Personal Grade level or lower . An example of this is "I Don't Want to Grow Up!", which requires the kid to be 6th Grade or less.

What happens, then, when the kid with the above Talent reaches 7th Personal Grade? Does he or she lose access to the benefits of the Talent, or does the requisite only apply when choosing the Talent, and not after the fact?
