Region 5 has already adopted the National Standards. According to these standards, a gymnast in Xcel Bronze will be an "in-house" level that states can choose to compete (similar to how some states compete Levels 1-3 now).
The only time JO level matters is when the gymnast begins Xcel.
Currently (adjust accordingly for the new levels) a level 3 could compete Bronze or Silver. A level 4 could compete silver or gold. A level 5 or level 6 could compete gold or platinum. A level 7 or level 8 can choose to compete Platinum or Diamond. A level 9 who wants to make the switch has to compete Diamond.
Once you are in the Xcel program, there are no USAG decided mobility scores until you reach gold. Then, you have to score a 31.0 AA (or 8.0 IES) to move to Platinum. And the same for Platinum to Diamond.
The minimum ages are Silver - 7; Gold - 8; Platinum - 9; and Diamond - 10. If a girl chose to compete Xcel and progressed through Diamond, once she was in high school, she could petition to compete the upper levels of JO ... or, since Level 9 and Level 10 are so similar, she could potentially catch the eye of a college gymnastics coach (maybe at a D2 school or even a D1 school if she has an event or 2 that are EXCELLENT) even if she continued competing Xcel.
We will have to see how it all shakes out in the future.
