I used to tell the students I was about to test with the WIAT-II that there would be some questions that would be too easy for them, some questions that would be too difficult, but we hoped most of the questions would be just right. As part of my routine, I used to ask students to turn on lights, turn off lights, open or close windows and doors until the room was comfortable for them. For this test, they were a class of one!
It did take more than a couple of hours for me to give the WIAT(the more experienced school psychologist could give the WISC-IV in about an hour). Because of the "floor" and "ceiling" on the questions, and because they were getting one on one attention, students rarely seemed to be bored and usually behaved and performed much better than they did in class.
