Categories are used to sort your achievement standards. These categories can be titled by subjects, or with any other organization system you choose.
To create a new category, navigate to your left toolbar on the dashboard page. Click on the "Achievements" tab, under the “All My Classrooms" heading.
Next, click the "Edit Standards" link. You can now add an achievement standard which will let you pick a new category.
When you create a new standard, you'll see a small link under the category bar that says "Edit Categories." If you click on that, it will take you to a screen that shows all your current active categories as well as an option for creating a new one.
