In order to add a school, after first logging in, select the schools list at the top of the page.
From there select the add school button
Fill out the information on the school page. Be sure to enter the total number of allocations for your K-D Test activations (This will take from your total pool of activations which you can check on the dashboard page).
Now create an account for the administrator of the school (at least one administrator account must be made). That user will receive an account creation e-mail to create their password and login for the first time.
