This study was undertaken to determine the suitability of the California Abbreviated WISC—Form 1 (CAW‐1) for use with WISC‐R subtests. Subjects were drawn from the files of previously evaluated students from two southern mountain communities. Examination of WISC records within the age and IQ ranges of the CAW‐1 (CA 8‐0 to 13‐6, IQ 50 to 80) indicated that our sample was not significantly different from the CAW‐1 noim group ( N = 148, r = .85 between CAW‐1 & WISC Full Scale IQ). WISC‐R recods ( N = 178) for the same ranges were examined and were found to be more highly predictive of Full Scale IQs ( r = .91, FSIQ = .98 CAWIQ + 2.2). Extensions of the age range from 6‐0 to 16‐11 and of the IQ range from 40 to 100 were attempted. Final results ( N = 284) indicated the CAW‐1 could be used with the WISC‐R over the full age range and for IQs ⩽ 100 with minor alteration ( r = .96, FSIQ = 1.09 CAWIQ ‐ 5.4). The second sample served for cross validation of these results. Using the alteration, results were consistent with original findings ( N = 202, r = .93, FSIQ = .98 CAWIQ + 2.2). It was concluded that the CAW‐1 was suitable for use with WISC‐R subtests with minor alterations.
