The Stability and Change of Language and Non-Language IQ Scores. Final Report.
Hopkins, Kenneth D.
The stability and change of verbal, non-verbal, and total IQ scores from group tests were investigated for students tested at Grades 1, 2, 4, 7, 9, and 11. Conclusions are discussed in detail, and the following recommendations are made: (1) Group intelligence tests should not be routinely administered in Grades 1 and 2 unless the users and interpreters of these scores have received extensive training in their meaning and limitations; (2) Non-language and non-verbal IQ scores must be interpreted even more cautiously than verbal IQ scores; (3) Teachers and other users of IQ scores from group tests need to be made aware of the fact that even when there is considerable overall stability, scores of a few individuals will vary greatly; and (4) No meaning should be attached to differences in verbal and non-verbal IQ scores prior to Grade 7.
