In the present study a short, self-administered intelligence test (SRA Non-verbal Test, Form AH) was correlated with the WAIS for an unselected sample of 29 mothers on the Providence Child Development Study. The correlation of .81 is significant and similar to the r of .82 between the WAIS Verbal Scale and the WAIS Performance Scale. It is concluded that the 10-min. SRA Non-verbal Test is a satisfactory and valid intelligence test instrument when dealing with specific groups of Ss but that WAIS IQ category labels should not be applied indiscriminately to SRA IQs.
