Before you start
You need an email address you can access and the authority to accept the terms on the school's behalf. For a public or government school, one person is named Account Manager and confirms they are an authorised representative.
The wizard
The setup wizard asks for the school name, the ownership type, an optional district, and then shows the consent text with a single checkbox. Accepting it emails you a copy of exactly what you agreed to, with the version and a link, so your records match ours.
Straight after setup
You land on the school dashboard. The usual next steps are to invite your teachers, create your classes, and import or create your students.
