Often times when our users are trying to reset a House Points competition, they accidentally delete Houses. Since Houses are just Rosters you've selected to be your Houses, it's a quick fix! No student Points were lost and those Rosters are still there, all you need to do is link those Rosters back to the House Points Dashboard.

If your goal was to begin a new competition, check out our article, Restarting a House Points Competition and Setting a Start Date.
