You must be a certified educational entity to purchase this Google Chrome license. You also must be approved for GSuite for Education before licenses can be deployed. Please visit the following link for more information:

Chrome Enterprise Management (CEM) for education allows access to the same features as the Chrome Enterprise perpetual license at a lower cost. CEM is a web based admin console you license from Google to remotely manage your Chrome device hardware. The education Chrome license is a perpetual management license that is a one time purchase that is valid for the life of the device but can be transferred to a like device in the event of a device issue. CEM allows a Chrome device to be set into Kiosk App Mode which keeps your digital signage locked to only play your Arreya channel and will automatically return to your Arreya channel if the device is turned off or loses connection. No worries about unwanted hijacking of your display to access other websites or having address bars on your digital signage. From your cloud-based Admin console the perpetual education license allows you to configure and enforce policies, install apps and extensions, manage users, manage apps, connect devices to your VPN and Wi-Fi networks, and manage other features of Chrome.

If you encounter a hardware issue and need to replace a device, you can transfer the subscription to another device of the same model (or equivalent manufacturer-provided replacement). You can not transfer a subscription to a device in another Google domain.
