Eighty‐four children from rural, urban, and suburban families were tested with the PPVT during a parent intervention program and with the SIT three years later as part of program evaluation. Results indicated the mean IQ on the SIT was substantially higher than expected based on the earlier PPVT scores. Sampling error and examiner error were excluded as explanations for the difference. These results suggest that the PPVT and SIT yield different scores and lack comparability.
