However to add to the original poster several coming of age stories have schooling provided by the movie makers. Is this something thats actually done or is it up to the parents to figure out
It depends on when the movie is being made, where it's being made, and how long it takes. Some states and countries have laws requiring the studios to provide tutors for child actors in most situations, but I'm not sure how long the laws have existed.
As an example a two week movie schedule during the school holidays is not likely to involve tutoring, while a four month schedule during the school year is likely to include tutoring.
