So DD, almost 6, is doing testing at the end or March/beginning of April, the WISC and the WIAT, we have never done fill in the bubble anything, do I need to familiarize her how to fill in a bubble for the achievement test. IS it like the scantron test I took growing up that the bubble has to be filled in completely and any eraser mark needs to be erased completely or the machine scores it wrong, or is this type of test totally different?. Just wondering if the WIAT is that kind of test or not, and if so, do I need to introduce fill in the bubble before then LOL?
