I would like a school revamp also, mainly to build a story for my sims through their teenage life stage.
schools for teens/kids could be a partial rabbit hole; a decorative school building with an open gymnasium, kind of like a community lot but with restrictions.
For grade school kids this could spawn events such as scout meetings where your sim kids and other kids in that neighborhood would actually meet to do scout activities. The only adults allowed into the gymnasium during this time would be scout leaders. Extra credit events for school performance could also spawn here in addition to things like fundraisers,school picture day, parent teacher conferences, lock-ins and maybe pta meetings where if your participates it could improve your kids performance.
It would also be nice to add small field trips where parent sims could chaperone.
For high school kids it would work the same way but with more for them to do of course. PROM would be spawned in the gymnasium, prom wouldn’t be a rabbit hole like in ts3. With the new styler career you could even “ pick outfits” if your sim gets a date. Of course with prom also comes pictures! Tutoring could also spawn here, pep rallies, bake sales, costume dances and other holiday dances if you have seasons, amongst other major high school events. Again certain events would have restrictions as to what age group is allowed into the open part of the school.
Each town would have its own school, high school or grade school, doesn’t have to be both. It would also be neat if you could chose where your kid(s) go to school. Some schools would strengthen skills like writing, logic, or painting while others strengthen the remaining. Also I think how teens interact with other teens should somehow influence what traits they could potentially end up with as a YA.
