Repeating a Grade at a Prep-School?

I’d really like to see data on how the repeat/not repeat thing plays out with non-athletic campus leadership positions senior year. I wonder if you made a list of the top 10 or twenty “biggest” (however you want to define that) leadership roles at a particular school: newspaper editor, school president(s) (in the case of co-presidents). senior class president,yearbook editor, etc. and looked at a five year average of which kids earn those positions, would repeats be over-represented? If repeats make up 35% of the student body, I wonder if they make up 50%, 60%, or even more of the kids who fill those roles.** It is easy to arm-chair quarterback this one and say from our living rooms, “heck no! Every kid has equal access to those roles if they have the chops.” But this is an empirical question, and it would be valuable to understand how it plays out statistically.

**Of course, you’d probably want to look at what % of those roles are filled by 4 year vs. 3 year vs. 2 year students, since that probably has a large impact as well. But obviously, someone with access to the numbers could slice and dice it to get a sense of the impact.
