Yes, this is not unusual for girls. Op still would do well to be sure his/her son knows that the landscape is much different for boys (fewer track scholarships due to football, more density at the top of HS boys running). I’m not saying it couldn’t happen, but I know way too many boys who are disappointed to find that being one of the top 10 in their state doesn’t yield any scholarship interest. But if he’s not concerned about scholarship money he’s in a great place, and can focus on long term development.
