Look, I stipulated the parental consent, and emphasized it in my post to make clear that the commission wasn't recommending mandatory screening.
The point, however, is that the screening targets "all youngsters" in public schools, pending parental consent. It's a massive and ambitious screening process that is envisioned, not something limited to at-risk kids, as your post implied when you wrote "in the schools if a child is presenting with behavioral or learning problems that has come to the attention of the school diagnostician, school psychologist or school nurse," or "screening can be as simple as situations like those listed in which a significant risk of psychological trauma exists."
