There are 3 boys in what this studio calls level 4. There are 2 boys in level 5. After that is the advanced level, no boys in it. The studio is small and the owner/teacher attended the Vaganova school in Russia since he was a child.
The three boys in level 4 will be 5th, 6th, and 7th grade this fall. My son is in 7th. The two boys in the older class, which is listed as being for 7th grade and above, are in high school. They have not been in dance as long as my own son. My son is very serious about dance and very good and disciplined. But, he is short. He is only 4'11 right now. The younger boys are shorter than him. But the older boys are several inches taller, like at least 6 inches taller. They look like regular, tall, boys.
I asked the owner again about moving my son up to the higher level. The owner finally leveled with me and said no, he wants to keep the three boys together. Well, out of the three boys, my son is the only serious one. The other two are not in to it and one acts half asleep for everything and the other is hyper and unfocused.
However, I get that my son looks like a child still. Saying he has the body of a child so he should stay with the boys until he is taller would make sense to me. But, I would expect him to have a growth spurt soon. His older brothers all had big growth spurts by 13 yrs old, so I would expect him to be several inches taller by next year at this time. I can definitely see the benefit of keeping son in the younger class, because he is smaller. And it does seem like this teacher is grouping by age more than by skill. Until they get to advanced level of course.
We are considering moving to where there is a bigger studio with a Vaganova trained instructor. We drive a ways for this and the other studios we have found in our area have a long drive. But my son loves this studio. I kind of wonder if he would actually end up unhappy in the higher level as it is held on a different day of the week so he would not see the younger boys anymore, at all. We do not live in that town and drive a ways, so we are not likely to drive just for the fun of it.
