I apologize if this information has been brought up here before but thought that this article might be of interest to anyone who is considering testing and which tool to request. This is a wonderful article by Deborah Ruf that details how the SB 5 compares to the LM form and explains the difference between ratio IQ and standard IQ. I found it very interesting and helpful in understanding my son's test scores. Hope someone else does too.
