Iowa is weighted, and things like these receive little weight compared to academic readiness. So with Iowa, a child who doesn't do extra work is not necessarily penalized. Here, in list form, it seems like whether the parents had to work and couldn't attend the parent-teacher conference is at least as important--and maybe more important!--than if the child is bored silly in school!
Oh, and on Iowa, I believe that having "pushy" parents is weighted as bad as (or maybe worse than?) having parents who don't show up for conferences. That's not at all reflected on the school's list.
