The newly released NSL exams conditions prohibit "external mouse or keyboard, whether wired or wireless." The School WILL ALLOW devices that have detachable keyboards, such as Microsoft Surface devices, that are connected to the main device. 
If you have such a device, or a similar device that does not have a permanent connection between the screen and any peripherals, please email Michele Wojciechowski to get approval for the device before you take any tests using ExamSoft.
