I suggested to our school GT coordinator that dd#2's school consider using the open enrollment program too b/c they have a few kids using it for math in school (parents pay). She didn't think that they would be interested despite the savings b/c it doesn't have the tutor thing. My guess would be that the tutor aspect serves like the available parent -- to answer questions -- and that the school doesn't want to make someone available to fill that role at school.
