I am quite sure our school district is somewhat anomalous, but they make it quite clear right from kindergarten that they want parents as involved in a child's education is the parent is able and willing. The level and depth of involvement with day-to-day school work they they place upon us to monitor and support learning - and to document our involvement daily - is almost burdensome to the point where sometimes I think, "Isn't that what teachers are for?" But I don't complain, because the result is that we are right there alongside our kids, participating in their education, knowing what they learn, able to keep a close eye on it.
Now to be sure, that school-parent interaction has gotten less as they've moved into and through high school. But the habits are so ingrained now, that we don't need the school prodding us to keep an eye open. Plus, they provide all the kids' grades, assignments, and stats on a web portal for us to check into any time we're compelled.
