The study was designed to provide a comparison of Peabody Individual Achievement Test (PIAT) and Wide Range Achievement Test (WRAT) scores in 49 learning disabled children (mean age 11 years at initial testing). (SBH)

The usefulness of the Myklebust Pupil Rating Scale (PRS) in diagnosing learning disabilities was studied in 516 third- and fourth-grade school children. It was concluded that the PRS is stable across populations and over time, and that no single subscale was sufficient to predict the total score. (PHR)

Two studies addressing the clinical validity of discrepancy criteria for identification of children with developmental language disorders (DLD) are reported: one with 256 preschoolers clinically defined as DLD, and one with 363 8-year-old controls. Factors contributing to underidentification in Study 1 and overidentification in Study 2 are…

The study involving 371 first graders in the initial sample and 206 in the follow-up evaluated the reliability and validity of the Matching Familiar Figures Test for its possible use in diagnosing the learning problems of young children, who may need special educational services. (Author/SBH)

Reviewed is research on the McCarthy Scales of Children's Abilities, which are designed to assess several areas of a child's cognitive and motor development from the age of 2 1/2 to 8 1/2 years. (Author)

To identify classroom behaviors that differentiate primary-level students with learning disabilities (LD) from their nondisabled peers, two scales of 83 items each were devised and piloted. Two subscales and 18 individual items were found to discriminate students later classified as LD and those referred but not subsequently classified as LD.…

This study investigated diagnosis of learning problems in 177 boys (ages 6-13) with behavior problems. The standard score discrepancy method and standard score plus low achievement method were more likely to identify children with above-average intelligence quotients as learning disabled, whereas a regression approach identified learning…

This article, which introduces six papers on the validity of distinguishing subgroups of children with language and learning disabilities based on discrepancies between academic attainment and intelligence test scores, comments on the papers' diversity in samples, measurement characteristics, and statistical approaches and outlines the studies'…

This study, involving 1,069 children (ages 9-14) referred for evaluation of learning disability, used 3 definitions of reading disability to provide criteria for 5 groups of children based on discrepancy between intelligence quotient (IQ) and academic achievement. Results question the validity of segregating children with reading deficiencies…
