First, you need a boarding school for your Sim children to attend.
Add-ons and custom content can help make your boarding school look nicer but aren’t necessary. The best part? No add-on packs, custom content, or mods required! Not possible, you say? Oh, ye of little faith! I’m going to show you how to have a fully functional boarding school in The Sims 4. Whatever your reasons, I have the solution. Maybe you’re just sick and tired of cleaning up after half a dozen messy rugrats. Have you ever wished you could send all those kids taking up space in the house somewhere else for a while? Maybe you’re playing a Perfect Genetics challenge and need more space in the house because you haven’t had a child with perfect genes yet.
