What Level do optionals start for WAG?
Anyway, JD is NOT like Xcel. There apparently is an Xcel program for boys (called Xcel) but I have no idea how many gyms offer boy's Xcel.
JD is an optional routine program for boys 11 and older who for whatever reason do not "fit" age and skill wise into the optional JO levels, or at least do not fit there as all around gymnasts. At out gym, the JD boys often practice with the JO optionals. Boys can and do move in and out of JD from JO. The way our coach explained the divisions in JD to me, JD 2 is for kids who are "optional age" (11 and up) but generally have compulsory level skills, and JD 1 is for boys with Level 8-10 skills. But in both divisions the kids create their own optional routines.
JD started just a few years ago, when they began having upper age limits for the JO optional Levels and at the same time, dramatically altered the "age in" date, because those changes threw many boys off their expected Level progression. But JD also opens opportunity for gymnasts working back from an injury, or who struggle more with certain events or skills and excel in others, who took time off from the sport, or who started "late." When JD started it had no divisions. Putting divisions in JD has made the program more useful and attractive and I think more gyms will be adding JD as time goes on.
Divisions in compulsory levels are as described above, one with bonuses competed, the other with no bonuses competed. Ideally, (I assume) division 2 encourages gyms to focus longer on clean, strong basics rather than pushing early for lots of bonuses and still do well at meets.
