I think that active schools would be cool in the future. It might fit a few play styles for some players
What types of schools though?
A single 'all age' type school like in current Sims games. TS3 has a rabbit hole for both children and teens.
A two tier type structure with an Primary or Elementary and Secondary divide. If we have preteens were would they fit?
A three tier type with Primary/ Elementary for kids, Middle or Junior High for preteens and a Senior High or Upper type school for the teens.
An 'private' type school that Sim parents have to pay for.
A scholarship type Grammar School that requires a pass to gain entry to.
I am from the UK and the system in my area was a three tier type structure of First, Middle and Secondary with the transfers at ages 8 and 12. I don't think this structure would work in The Sims though. The American type of Elementary, Middle and High with the transfers at 11 and 14 could work if we have preteens.
