The purpose of this study was to compare and analyze test scores on the Woodcock-Johnson Psycho-Educational Battery (Battery) and the Wechsler Intelligence Scale for Children -- Revised (WISC-R) for a sample of subjects classified as learning disabled and a sample of subjects classified as gifted and talented. Subjects were randomly selected and included 51 school-identified learning disabled students and 46 school-identified gifted and talented students. All subjects were administered the Woodcock-Johnson Tests of Cognitive Ability (WJTCA), the Woodcock-Johnson Tests of Achievement (WJTA) and the WISC-R. The specific areas of investigation for each sample included: (a) performance on the Achievement-Aptitude Profile of the Battery, (b) comparability of full scale scores, (c) performance on the Cognitive clusters of the Battery, (d) performance on the Achievement clusters of the Battery, and (e) the magnitude of Verbal-Performance Scale Score discrepancies on the WISC-R. Results indicated that the majority (74.5%) of the subjects classified as learning disabled and a few (10.9%) of the subjects classified as gifted and talented evidenced a moderate or severe deficit on the Achievement-Aptitude Profile. The subjects classified as learning disabled scored significantly higher on the Full Scale score of the WISC-R than on the full scale score of the WJTCA, while the difference between full scale scores was not significant for the subject classified as gifted and talented. An important finding was that scores obtained on the Reasoning cluster were invalid for subjects in both samples. Further analyses indicated that the alternative clusters, Oral Language and Broad Reasoning (Woodcock, 1983) provided a more accurate appraisal of abilities for each sample. Overall, the study provided insights regarding test performance on the Battery and the WISC-R for these two diverse samples.

Relatively recent federal education initiatives, such as No Child Left Behind (NCLB; 2001), have focused on school accountability for student achievement including achievement of traditionally at-risk populations, such as students in special education, students from low-income or high poverty areas, and students who speak English as a new second language. Additionally, these federal initiatives also mandate that all students take the same test measuring grade level standards despite research that has demonstrated that students from at-risk populations are sometimes at a disadvantage on high-stakes tests. Furthermore, initiatives such as NCLB are often at odds with other education initiatives such as IDEA, which states that students in special education should be tested at their respective level. Therefore, the current study proposed to examine the relationship between Cattell-Horn-Carroll cognitive abilities and performance on a state-wide high-stakes achievement test. There currently are no studies examining such a relationship. This study used Multivariate Regression Analysis, in order to investigate the relationship between CHC cognitive and achievement abilities and performance on a state-wide high-stakes achievement test, namely the ISTEP+, with 45 children who had been referred for a psychoeducational evaluation to determine special education eligibility and who had also taken the ISTEP+. No statistically significant result was found between the WJ-III-COG broad CHC abilities and performance on the English/Language Arts and Math performance of the ISTEP+. Furthermore, no statistically significant result was found between the WJ-III-ACH and Math performance on the ISTEP+. However, a statistically significant result was found between the WJ-III-ACH Passage Comprehension subtest and the English/Language Arts portion of the ISTEP+. The results indicated that students who had higher scores on the Passage Comprehension subtest also had higher scores on the English/Language Arts portion of the ISTEP+. The current study took a step forward in the area of the relationship between CHC and academic achievement, particularly state-mandated high-stakes testing given the dearth of research in this area. Given the data from the current study indicating a statistically significant relationship between Passage Comprehension and English/Language Arts from the ISTEP+, the current study has practical implications for school psychologists, especially when school psychologists are being asked to make predictions regarding a student’s academic achievement. Results of the current study might help elucidate reading problems and recommended interventions for those reading problems. / Department of Educational Psychology

This study identified a sample of children with specific learning disabilities according to Public Law 94-142 criteria. The primary purpose of the study was to examine whether sample member's intravariability of WISC-R subtest scaled scores was related to their reading achievement gain. A second purpose was to determine if any relationship existed between intelligence and reading achievement gain. Eighty-four Resource placed elementary students composed the study sample. They ranged from six to eleven years of age, and were primarily male caucasian. Since 1989, each sample member had been administered the WISC-R once; and , each sample member had been administered the WJTEA-R twice, with at least 12 months separating the two administrations . Results identified no relationship between WSIC-R subtest scaled score scatter and reading achievment gain on the WJTEA-R. A positive correlation was identified be tween intelligence level and academic gains in reading. Important ancillary correlations of significance identified for all subjects included a negative relationship be tween the variable Age and the variables Intelligence , Academic gain, and the WISC-R FD factor . When intelligence was held to within average parameters significant correlations were identified between the variable Achievement and the variables Age and Time (negative), and with the WISC-R FD and VC factors (positive) . Multiple regression analyses indicated the FD factor best able to predict academic gain for this group. It is probable, that in the identification of learning disabled students, that the identification of processing disorders (as with previously sought patterns) is not viable. It may be that the only key characteristics are intellectual level and severe discrepancy.

The Wide Range Assessment of Memory and Learning (WRAML) is a relatively new instrument used in the assessment of memory in children. The purpose of this study was to examine the validity of the WRAML by comparing the performance of children on both the WRAML and the Woodcock-Johnson Tests of Cognitive Ability- Revised (WJTCA-R). Subjects for the study were children in treatment for a brain tumor at a regional children's medical center. Fifty children participated in the study ranging from ages 6 to 17. A multiple regression analysis was conducted to determine which of four selected clusters from the WJTCA-R would have the highest correlation with the Verbal Memory Index (VERI) from the WRAML. The Short-Term Memory (GSM) cluster had the highest correlation ( r = .82) as predicted. A Pearson's product-moment correlational analysis was conducted between the Visual Processing (GV) cluster from the WJTCA-R and the Visual Memory Index (VISI) from the WRAML. GV was found to have a high positive correlation ( r = .63) with VISI. A similar analysis was conducted between the Long-Term Retrieval (GLR) cluster from the WJTCA-R and the Learning Index (LRNI) from the WRAML. GLR was found to have a high positive correlation ( r = .81) with LRNI. Finally, a correlational analysis was conducted between the Broad Cognitive Ability (BCA) scale from the WJTCA-R and the General Memory Index (GENI) from the WRAML. A high positive correlation ( r = .87) was found between these most global measures from the two batteries. The observed correlation between BCA and GENI was much higher than anticipated. The author concluded that neurological impairment had affected subject memory and intellectual functioning in similar ways. The results do not generalize to children who have not had similar decrements in cognitive functioning. Future research should establish a baseline correlation between the two instruments with a non-impaired population.
