We recently installed a smartboard in a Nursery classroom and have just received a call from the school saying that the board is too high. The bottom of the board is 68cm/26 inches from the floor. Going by installs in other schools this seems to be the norm. Just looking to see if other people have lower boards in their nursery classes. Please let me know as the school want us to change the projector and lower the board for free. Thanks in advance.
