While I think the pack you are suggesting is somewhat over the top, I think bringing back actual in-game schools would be a good idea. Any time a new career path or skill set is suggested, I am all for it. Sims who start on the Teacher career path could start out as Elementary Assistants and work their way up to High School Teacher and then Principal or School Superintendant. Additionally, your child or teen sims could pick and choose classes and build a skill level for each. Some of these skills could transfer into Young Adulthood; Math classes could translate to additional Logic points, Home-Economics could translate into Cooking, Shop classes could translate into Handiness (though I personally feel that Handiness needs to be split up much like Creativity has been over the past few games). And I for one would love take a class in Sim History. Perhaps a different level of awkwardness could be added if sim Teachers ended up teaching their own children.
