Schools can be quite big and contain a number of different classrooms and departments. To this end it is important for students, teachers and guests to be able to find the correct room quickly and easily. With this in mind it is therefore important to label each room. This can be done with a simple numbering system or by labelling each class for the subject or grade that is taught within. These signs need to be clearly readable and could be in a simple text on a plain background affixed to the appropriate door.
