AbstractForty‐seven talented fourth graders were assessed on different WISC‐R short‐form combinations in order to determine which short‐form was the most effective predictor of high Full Scale WISC‐R IQ. The short‐form combinations of Similarities + Object Assembly + Vocabulary subtests (SI‐OA‐VO) or Similarities + Object Assembly subtests (SI‐OA) were more effective in this regard than eight other WISC‐R short‐form combinations, the Slosson Intelligence Test, and school grades in Math, Language, and Reading combined. The findings are of relevance
