The ClassCalc Management Layer

Our management layer strikes a perfect balance of ensuring a 100% safe and fair testing environment, without giving teachers access to or control over student devices.

How? Here's the deal:

  1. Students agree to lock their devices onto ClassCalc, and in exchange, teachers allow students to use ClassCalc in class.
  2. During lockdown, students will not be able to leave ClassCalc, and will not get any notifications, calls, texts or outside distractions.
  3. Lockdown does not give teachers control or access to student devices. The only information they are given is whether the student is in lockdown mode or not.
  4. If a student leaves lockdown in the case of emergency, the teacher will be notified. Students cannot rejoin a test session until the teacher resends an invite.
