Teachers choose the tag categories they see in the app.
When you first use the app, or after an app upgrade, Blippit Boards shows you ALL available tag categories by default to give you the maximum amount of control and choice over what you use in your own school account.
The main factor is whether you're in England or Wales. You will need to follow these steps first.
Now that you've hidden categories that are irrelevant to your country, that is the large part taken care of.
You can continue hiding other categories in the same way now. For example
*After an app upgrade you may need to show/hide the tag categories again if your choices get reset after the update.
