I would not be testing my child on the SBLM, but in terms of whether they are the same - the SBV manual has a table comparing the SB5 and SBLM scores of a range of children, it clearly shows that there was a significant difference between the scores obtained for the two tests... Children scoring high, but not in the range that would attract extended norms on the SB5 were scoring 170+ on the SBLM. If I remember correctly most children scoring 140+ on the SBV had scored 170+ on the SBLM. The 146 WISC kid quite possibly IS a 183 SBLM kid.... I just don't see any point to the SBLM anymore though, I don't understand why it is still being used.
