Concurrent validity of the Kaufman Assessment Battery for Children (K-ABC) was investigated with 42 English-speaking Mexican-American Head Start children. Correlation coefficients between the five K-ABC Global Scale Standard scores and the three Wechsler Preschool and Primary Scale of Intelligence IQ Scale scores were typically in the .50s and…

The concurrent validity of the Wechsler Preschool and Primary Scale of Intelligence (WPPSI) was assessed against the McCarthy Scales of Children's Abilities in a sample of 39 Mexican-American preschool children from low socioeconomic status background. Results indicated some specific support for the WPPSI's concurrent validity. (Author/BS)

Finds that the Wechsler Preschool and Primary Scale of Intelligence and the Florida Kindergarten Screening Battery were highly similar as predictors of future reading ability for 59 5-year-old, low income, Mexican-American children. Perceptual performance subtests in both measures correlated better with reading ability than verbal subtests. (SV)

Tests causal models of verbal and performance IQ in 69 Mexican-American children of low socioeconomic status. Years of mother's education were correlated with IQ at 3 years and at 6 to 8 years, but traditional/nontraditional attitudes showed conflicting correlations over time. The adequacy of standarized IQ tests for this population is questioned.…

In a study of the effects of mixing children of different backgrounds, 18 disadvantaged Mexican-American children were integrated into classes with 36 advantaged Anglo peers to see if the intellectual performance of the Mexican-Americans would be favorably affected. Comparisons were also made between 18 children of the same ethnic group who were…

Effects of language of administration on IQ and predictions of letter learning and achievement were investigated for Anglo and bilingual Mexican American preschool children. Significant IQ differences were associated with language of test administration. No significant differences among predictions of letter task performance were obtained for…

The Kaufman Assessment Battery for Children and Wechsler Preschool and Primary Scale of Intelligence (WPPSI) were administered to Anglo- and Mexican-American children aged four to six. Both scales measured similar, but not identical, intellectual and achievement factors, indicating concurrent validity. Anglo children scored higher on WPPSI verbal…

A short term preschool readiness program was designed in 1967 to employ nonpedagogically trained middle class mothers as teachers for preschool disadvantaged children. The children chosen for this study were 43 Mexican-Americans and five Negroes from lower class families. Three classrooms, consisting of 12 children and three mothers each, were…
