The WISC‐R and the Slosson Intelligence Test (SIT) were given to 69 randomly selected children in grades one through six in an urban school system. A regression equation for predicting WISC‐R full scale IQ from SIT was developed. Previous studies had reported that SIT IQs tended to be consistently higher than WISC‐R IQs. The present study revealed that SIT IQs were considerably higher than WISC‐R IQs in the upper range and slightly lower in the lower range. A possible reason for the discrepancy is that the present study used a normal population and previous studies used restricted ranges. It was concluded that the SIT provides a good estimate of WISC‐R full scale IQs when a regression equation is used. It was recommended, however, that educational placement decisions should not be made on the basis of any single IQ measure.
