If you have already created houses for your students and you would like to reset all settings to start a new competition, you can choose to delete houses. This will not affect any points that students have earned.
Go to House Points → Options
Head to https://liveschoolapp.com/#/house-points to see all of your House Points settings and click Options.
Click Delete Houses
To restore House Points to the default settings with no Houses, click Delete Houses.
This will clear the Dashboard and remove any Houses you've created. All of your data, and the rosters you used to create the Houses, will not be affected.
