To determine the intertest reliability of the Beery Developmental Test of Visual Motor Integration (VMI) and the Bender Visual Motor Gestalt Test (BGT), 64 six to nine year olds were administered both tests.

The study involving 145 students (5-13 years old) referred for psychological evaluation explored the consequences of retesting upon student placement and the changes in test results. (SBH)

Eighty-three children (mean age 9 years) with learning disabilities or multiple physical or sensory handicaps were tested using the Peabody Individual Achievement Test (PIAT) and one or more standard measures of intelligence to assess the value of the PIAT as an effective measure and screening device of educational achievement. (LC)

The effectiveness of the Test of Language Development was studied with 32 children (ages four to nine years) who had speech and/or language problems. (Author/DLS)

The study investigated the temporal stability and estimated the standard error of measurement for subtests of the Peabody Individual Achievement Test (PIAT) with 60 learning disabled and emotionally handicapped children (9 to 13 years old). (Author/SBH)

To more easily distinguish patterns of reading and spelling errors, two parallel, standardized reading and spelling forms were designed (based on E.

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)

A Behavior rating scale, usable for parents and teachers, was devised to measure overt behavioral characteristics of children with learning disabilities. (SBH)

Four components of reading speed were identified, and a measure of the first component, reading speed of known vocabulary, was investigated on a mixed sample of 84 boys (6 to 14 years old), which included a high proportion of retarded readers. (Author/GW)
