I just got DS4's test results back today. She used the EXIQ to extend his scores for the SB5. I am new to this so hope I am using the correct terminology. She also used CSS to interpret age equivalent data since she tested him out of level. I am grateful to have all the information...but I had a hard enough time dealing with the original FSIQ before turning the page to see the EXIQ. I wish I could have eased into it a little more. I am sticking with the FSIQ, even if she does feel that the other is a more accurate representation. ; ) Maybe that is denial but it works for me.
