Given the growing importance of support needs assessment in the field of intellectual disability, it is imperative to develop assessments of support needs whose scores and inferences demonstrate reliability and validity. The purpose of this study was to examine the criterion validity of scores on the "Supports Intensity Scale-Children's…

In surveying the literature on assessment of cognitive abilities in adults and children, it is easy to assume that the proliferation of test batteries and terminology reflects a poverty of unifying models. However, the lack of recognition accorded good models of cognitive abilities may reflect inattention to theoretical development and injudicious…

Purpose: The purpose of this study was to examine whether the levels of cultural intelligence (CQ) of principals and teachers influence Latino students' achievement. The study first tested the applicability of Ang and Van Dyne's (2008) Cultural Intelligence Questionnaire (CQS) for the measurement of principals and teachers' CQ levels by construct…

The interpretation of subtest profiles from intelligence testing remains popular among many practitioners who use subtest performance to draw diagnostic conclusions, in spite of criticism by some researchers, who point to the low reliability and predictive validity of subtest scores in predicting achievement outcomes. Prior research outlines two…

A reverse engineering approach to automatic item generation (AIG) was applied to a figure-based publicly released test item from the Organisation for Economic Cooperation and Development (OECD) Programme for International Student Assessment (PISA) mathematical literacy cognitive instrument as part of a proof of concept. The author created an item…

The noncentral chi-square approximation of the distribution of the likelihood ratio (LR) test statistic is a critical part of the methodology in structural equation modeling. Recently, it was argued by some authors that in certain situations normal distributions may give a better approximation of the distribution of the LR test statistic. The main…

Cultural capital, originally a general sociological concept, has been transformed into a construct that is often applied in predicting scholastic attainment. Intellectual ability (IQ) has also been proven to be a strong, although basically psychological, predictor of educational attainment. However, these strands of research have hardly been…

Prospective teachers (N = 171) read an essay that manipulated the ethnicity of the student-author (European American, African American, Asian American, or none mentioned). They then rated the author's intelligence and probable future success and estimated the author's GPA. The Asian American student was seen as more intelligent than the control…

Some researchers have argued that discrepant broad index scores invalidate IQs, but others have questioned the fundamental logic of that argument. To resolve this debate, the present study used a nationally representative sample of children (N = 1,200) who were matched individually for IQ. Children with significantly uneven broad index score…

Third grade elementary school children solved tests on mathematical reasoning and numerical facility. Metacognitive skillfulness was assessed through think aloud protocols, prospective and retrospective child ratings, teacher questionnaires, calibration measures and EPA2000. In our dataset metacognition has a lot in common with intelligence, but…

The importance of validity and reliability in the componential analysis of human intelligence is discussed. The roles of construct, internal, external, convergent, discriminant, and ecological validity in componential analysis are outlined. Within-replication (internal-consistency) and between-replication (alternate-forms or test-retest)…

None of the several objective indices of cultural bias shows any significant indication of bias in any of the standardized tests of intelligence examined when they are used with blacks and whites. (Author/IRT)

Multiple regression is used to discover interconnections between IQ and vocabulary test scores as one variable, and socioeconomic factors as the other. Results show total variance as explained by predictors is never more than eight per cent, indicating differences in IQ scores are not attributable to environmental factors. (RW)

Investigates the general factor and uniqueness characteristics of the individual tests of the Woodcock-Johnson Test of Cognitive Ability-Revised (WJTCA-R). Only 2 of the 19 WJTCA-R tests examined had low general factor loadings, while 2 had low uniqueness. All other tests had medium or high uniqueness. Discusses implications for clinical…

Correlations and mean score differences between IQs derived from the Universal Nonverbal Intelligence Test (UNIT; Bracken & McCallum, 1998) and the Wechsler Intelligence Scale for Children-Third Edition (WISC-III; Wechsler, 1991) were compared. Participants were Limited English Proficient (LEP) Mexican-American elementary school students, who…
