For many elementary and secondary school students, a standardized group ability test score may be found in their cumulative record. such results are often used for placement in instructional programs. However, with relatively little research and conflicting results, it remains unclean if group ability test scores are appropriate to be used for any purpose. This study investigated the validity of using the Test of Cognitive Skills - Second Edition (TCS/2) as a measure of intelligence with special education students, as compared to the Wechsler Intelligence Scale for Children - Third Edition (WISC-Ill). To investigate the relationship between the group-administered TCS/2 and the individually administered WISC-Ill, scores of 66 students (grades 6 through 11) were compared. Pearson product-moment correlations revealed significant, positive relationships between the CSI and most scores of the WISC-Ill. However, despite significant relationships, the correlations are modest at best. T-tests revealed significant differences between the CSI and all WISC-Ill score means. CSI scores were significantly lower than WISC-Ill scores. Therefore, the CSI is not recommended as a valid source of information to be used in decision making regarding special education students. Further research is needed to determine the validity of the CSI with other student populations. |
