Yes. Students who use Chromebooks must log in to the Chromebook with their school-issued Google account in order to receive the LanSchool Air app and extension as configured within Google Admin.
For students using Windows or macOS devices, the LanSchool Air agent must be installed on student's devices. LanSchool Air allows teachers to provide these students with a unique link at the start of class to quickly provide them with the installer and add them to the right class. Students will need administrator permissions on their devices in order to install the client themselves. For more information on installing the client this way, see Installing LanSchool Air for Windows Student or Installing LanSchool Air for Mac Student.
