MAG is age limited at optional levels. YOu have nationals ages, and then older ages.
Level 8 nationals age is 12...older is 13-14
L9 Nationals: 13-14, older 15-16
L10 15-19.
That is JO. JE is the elite path. For that path, you can be 11 yo at L8 but the rest are teh same. JD is Junior Development. It is a level for kids that are late starters, want less hours, or maybe are too old for the level they could be successful at. Ages at JD are 11-14 adn 15-19.
If you are 13, you can be a compulsary gymnast, or L8, 9 or JD.
At 15, you can be compulsary, or 9,10, JD.
At 17..compulsary, 10 or JD.
USAG says that boys at the older ages of L8 and 9 should go to state and regionals. Texas and R3 have gone against this and are saying that they cannot.
