The review of the Test of Written Language-2 (TOWL-2) raises concerns about alternate forms reliability, subtest reliability, content validity, and omissions. It concludes that the TOWL-2 is an expanded and greatly modified version of the original test but may not be appropriate for identifying a student's specific writing problems. (DB)

Reanalysis of data derived from a meta-analysis of the Wechsler Intelligence Scale for Children-Revised, using a learning disability index derived from a principal-components analysis, found that the test discriminated reliably between 9,372 learning-disabled children and their non-disabled peers.

To assess Feuerstein's Learning Potential Assessment Device's (LPAD) ability to identify deficient cognitive functions, Raven's Standard Progressive Matrices were administered to 176 elementary/junior high students--25 percent were rescored--and 12 complete LPAD reports from a university educational clinic were reanalyzed. Correlations were…

Scores on the Einstein Assessment of School-Related Skills for 164 elementary-level children were correlated with reading and mathematics test scores, teacher ratings, and presence/absence of school-diagnosed learning difficulty. Results showed the Einstein was significantly related to achievement and generally predicted learning difficulty as…

The Clock Drawing test was administered to 143 regular education students (grades 1-4) to determine approximate grade levels at which skill on the test may be expected and to 30 students with learning disabilities. For the regular children, scores improved most between first and second grade. The disabled children scored significantly lower than…

The use of standardized psychoeducational diagnostic instruments to identify learning disabilities was evaluated with 19 students (ages 7 to 13) with sensorineural hearing impairments. Students with hearing impairment were found to demonstrate learning disabilities with a frequency similar to that found in students with normal hearing, suggesting…

This study, with 66 regular classroom children and 52 children with learning disabilities, found high correlations among the Cognitive Levels Test, the KeyMath-Revised measure, and the Woodcock Reading Mastery Tests-Revised. Overall, 81 percent of subjects were correctly classified using the three-instrument battery. (Author/DB)

School psychologists function as experts in the diagnosis of childrens' educational difficulties. Can the decision-making activities of school psychologists be characterized as expert? Practicing school psychologists (N=10) reviewed cases of children (N=120) being considered for placement in learning disabilities programs. A case consisted of 17…

Analysis of Kaufman Assessment Battery for Children (K-ABC) Sequential and Simultaneous Processing scores of 94 children (ages 6-12) with learning disabilities produced factor patterns generally supportive of the traditional K-ABC Mental Processing structure with the exception of Spatial Memory. The sample exhibited relative processing strengths…

Learning disabilities among adults are more prevalent than was once believed, although estimates of numbers are difficult to make. Problems faced by adults with LD include difficulties with academic and information processing and adult life adjustment. Many adults with LD exhibit strengths that enable them to compensate for their disabilities and…

This study investigated the construct validity of five perceptual traits (auditory discrimination, visual discrimination, visual memory, visual-motor coordination, and auditory to visual-motor coordination) with five simulated work samples (union assembly, resistor reading, budgette assembly, lock assembly, and nail and screw sort) from the Jewish…

Two experiments were conducted to assess the performance of freshmen chemistry students with poor spatial visualization skills. In the first experiment, 31 chemistry students with academically deficient backgrounds completed a diagnostic test of their ability to visualize and interpret pictorial representations of simple molecular structures. At…

A public school district in Alabama uses the Otis Lennon School Ability Test (OLSAT) in place of the Wechsler Intelligence Scale for Children (Revised) (WISC-R) as a screening device for students who are referred for possible special education placement. To determine the relationship between the two tests, Pearson product moment correlation…

Comparisons of Wechsler Intelligence Scale for Children-Revised scores, for 24 children with learning disabilities demonstrating a low verbal, high performance intelligence quotient (IQ) discrepancy and 33 slow learning children having uniformly low verbal and performance IQs, revealed few cognitive differences beyond the Performance Scale…

This study examined the concurrent validity and diagnostic efficiency of the Kaufman Brief Intelligence Test (K-BIT) with 75 elementary and middle school students with learning disabilities, who had been referred for triennial multidisciplinary re-evaluations. High and significant correlations were found between the K-BIT and the Wechsler…
