I get that plenty of rate modifiers have strong links to driving safety like age and marriage status. However, in my limited opinion, there's no way "honor roll" has anything but the weakest link to safe driving as the barrier to achievement varies drastically on a school-to-school basis. Insurance companies are data driven but data (especially healthcare data) lags so long that I wouldn't be surprised if discounts for running a wellness program were founded purely in speculation. This article seems to back that assumption with hard proof as well.
