Standard Age Scores on the Stanford-Binet Intelligence Scale: Fourth Edition (SBIV) and WISC-R IQs of 51 urban black males receiving special education services were compared. Correlations between the SBIV Composite scores and WISC-R Verbal, Performance, and Full Scale IQs were 303, .826, and 3 7 respectively. Correlations between all combinations of scales ranged from .612 to .888, median r = .723. SBIV Composite mean scores did not differ significantly from the mean WISC-R Full Scale, Verbal, and Performance 1Qs. Regression analysis of the three subgroups (BD, LD, and EMR) indicated that the SBIV possesses differential validity for each group. Tabular comparison of precision of classification between the SBIV and the WISC-R yielded a 78% agreement. These data suggest that the SBIV possesses utility for assessing the intelligence of black students classified as BD and EMR. However, the use of the scale with LD students is unsupported. Since the publication of the Stanford-Binet Intelligence Scale: Fourth Edition (SBIV) (Thorndike, Hagen, & Sattler, 1986a), a limited number of independent validation studies have appeared in the literature. One of the earliest studies (Livesay, 1986) compared SBIV Composite Standard Age Scores (SAS) and WISC-R IQs of 166 gifted white elementary children. The means were significantly different (MWISC-R = 123.33, MSBIV = 120.63), and correlations between the various scales were .55 (WISC-R vs. Composite), 3 8 (WISC-R vs. Verbal Reasoning), .28 (WISC-R vs. Abstract/Visual Reasoning), .38 (WISC-R vs. Quantitative Reasoning), and .31 (WISC-R vs. Short-Term Memory). Livesay found that SBIV SAS were slightly lower than WISC-R IQs and indicated that while the SBIV is an acceptable alternative to the WISC-R, use of the SBIV in evaluation of the gifted would reduce the number of students meeting eligibility requirements.A second study (Carvajal & Weyand, 1986) reported a correlation of .78 between SBIV SAS and WISC-R IQs for 23 third-grade children. Further, there was no significant difference between the SBIV Composite mean (1 13.3) and the WISC-R Full Scale mean (1 15). These outcomes prompted the authors to conclude that the SBIV, particularly the "General Purpose Abbreviated Battery," should serve as an acceptable alternative evaluation instrument.Contrary to Carvajal and Weyand's finding, Rothlisberg (1987), using a sample of 32 first and second graders, obtained a significant difference between the WISC-R Full Scale mean (112.53) and the SBIV mean (105.53). However, the magnitude of the correlation between the SBIV SAS and WISC-R IQs was similar ( r = .77). In a study with children receiving special education services, Phelps, Bell, and Scott (1988) compared SBIV SAS and WISC-R IQs for 35 LD students. They found a close correspondence Requests for reprints should be sent to between the respective means (MWISC-R = 95.6, M~B I V = 93.92) and a significant correlation between the various SBIV and WISC-R scale scores. They concluded that, for LD students, the SBIV should yield IQ scores si...
