The same working memory and reading and writing achievement phenotypes (behavioral markers of genetic variants) validated in prior research with younger children and older adults in a multi-generational family genetics study of dyslexia were used to study 81 adolescent and young adults (ages 16 to 25) from that study. Dyslexia is impaired word…

The purpose of this study was to assess the relative contribution of teacher and tutor ratings of inattentive behavior in two different instructional settings in predicting students' performance on fraction concepts and whole-number calculations. Classroom teachers rated each student's attentive behavior in a whole-class setting and tutors rated…

The investigators measured 7 literacy skills in a group of 21 school-age children with mild to moderate sensorineural hearing loss (MSNH group), and compared the scores to those of 2 age-matched groups: children with dyslexia (DYS group) and, as a control, typically developing hearing children (CA group). The MSNH group performed consistently…

The Wechsler Intelligence Scale for Children-Revised Full Scale IQ did not yield valid predictions of achievement of educable mentally handicapped students in a public school setting, as measured by the Wide Range Achievement Test (WRAT). (Author/CM)

Forty trainable mentally retarded students were concurrently administered the Stanford Scale and the Wide Range Achievement Test (WRAT). WRAT reading, spelling and arithmetic subtests were regressed on Stanford intelligence quotients. Predictions were statistically valid. Derived regression equations are reported. (Author/CP)

The ratings of the Achievement and Intellectual Screening scales of the Personality Inventory for Children (PIC) are compared with scores on the Wechsler Intelligence Scale for Children-Revised (WISC-R) and the Wide Range Achievement Test (WRAT) to determine the efficacy of using the PIC as an index of children's performance on such measures.…

Predictive validity of the Weschler Intelligence Scale for Children-Revised (WISC-R), was investigated with 174 Chicanos and 94 Anglos, ages 10-11, who were referred for psychological services. Wide Range Achievement Test Reading, Spelling, and Arithmetic subtest scores were each regressed on WISC-R Verbal, Performance and Full Scale Intelligence…

Interrelationships among IQ, academic achievement, and teacher ratings of pupils' classroom achievement were evaluated in a large sample of children from various racial and socioeconomic backgrounds. A substantial relationship between standardized measures of IQ and achievement was found and was independent of race, but decreased with increasing…

As part of a longitudinal study of the acquisition of reading skills, a study tested kindergarten children at the beginning and end of their kindergarten year. The children were also observed for nine full days in their classrooms. Subjects were approximately 650 children in two cohorts. Data were collected in three school districts in Illinois,…

Biased assessment instruments and practices can lead to over-representation of minority children in special education classes. This paper analyzes the amount of variance in Mexican-American achievement test scores attributable to sociocultural factors. Fifty learning disabled Mexican-American elementary school students completed the Peabody…

This study examines the usefulness of the Wechsler Intelligence Scale for Children-Revised (WISC-R) in predicting the reading achievement of 74 disabled readers in grade 3 on the word recognition subtest of the Wide Range Achievement Test (WRAT). The WRAT word recognition subtest was used because previous research has demonstrated a high positive…

The concurrent validity of the third grade, New York State Pupil Evaluation Reading Program (PEP) reading test was examined with the following standardized tests: the Durrell Silent Reading Test, the Gilmore Oral Reading Test, the Wide Range Achievement Test (WRAT), the Verbal IQ of the Wechsler Intelligence Scale for Children (WISC), and the…
