Visuo-spatial reasoning tests, such as Raven's matrices, Cattell's culture-fair test, or various subtests of the Wechsler scales, are frequently used to estimate intelligence scores in the context of inter-racial comparisons. This has led to several high-profile works claiming that certain ethnic groups have lower intelligence than others,…

The Naglieri Nonverbal Ability Test (NNAT) was developed to more equitably identify students of color, as it advertises itself as a culture-fair measure. In this meta-analytic evaluation, we aimed to investigate: (1) the generalizability of validity evidence of NNAT by checking its construct and criterion validity with other measures (Part I); and…

Verbal and quantitative reasoning tests provide valuable information about cognitive abilities that are important to academic success. Information about these abilities may be particularly valuable to teachers of students who are English-language learners (ELL), because leveraging reasoning skills to support comprehension is a critical aptitude…

Effective talent-identification procedures minimize the proportion of students whose subsequent performance indicates that they were mistakenly included in or excluded from the program. Classification errors occur when students who were predicted to excel subsequently do not excel or when students who were not predicted to excel do. Using a…

Translated and noverbal tests are discussed as techniques for measuring intelligence and language differences in the Chicano child. (NQ)

The purpose of this study was to compare the effectiveness of the Raven's Standard Progressive Matrices, the Naglieri Nonverbal Abilities Test (NNAT), and the Iowa Test of Basic Skills (ITBS) in selecting for ethnically diverse students who may be gifted. The participants of the study were 175 students enrolled in Grades 3-5 and Grade 8 in a…

The Non-Verbal Test of Cognitive Skills (NTCS), by Boyd and Johnson, attempts to address the problems of non-verbal and culturally biased testing instruments in three directions: (1) Test items should be developed which cannot be linked to a specific culture or environmental source as previous learning; (2) Assumed language facility should be…

The Key Assessment System, consisting of test instruments which measure psychological functioning, work related competencies, and attitudinal and motivational characteristics, is described. The system is a vocational assessment battery designed to differentiate levels of psychophysical capabilities in a nondiscriminatory manner. It provides a…

The 50 nonverbal tests in this bibliography assess aptitude and cognitive skills using various nonverbal means, such as pictures, symbols, or figures. They are useful in testing those who may have reading difficulties or those for whom English is not the primary language. Not included are aptitude measure that have both verbal and nonverbal…

The D-48, a nonverbal test of general intelligence, was administered to 250 Mexican American and Anglo American community college students. Analysis of D-48 scores indicates no significant differences due to ethnicity or gender; adequate internal consistency and test-retest reliability; and significant correlations with grade point average and…

Performance was better for children above six years of age and better in Spanish than English. It is suggested that the Peabody Picture Vocabulary Test never be used to assess the general intelligence of Mexican American children, because it likely underestimates their ability. (Author)

This study examined the effectiveness of the Naglieri Nonverbal Ability Test (NNAT) in identifying gifted black and Hispanic students in a total population of 20,270 students (K-12). Analysis indicated that similar percentages of white (5.6%), black (5.1%), and Hispanic (4.4%) children earned an NNAT score in the 95th percentile rank. (Contains…

Non-verbal tests are paper-and-pencil tests that are designed to measure cognitive processes that do not involve verbal language. Such tests use shapes, patterns, diagrams, and sequences to measure general intellectual skills of a non-verbal nature. The use of such tests in schools is described. Performance tests using concrete apparatus are…

This instrument assesses readiness for school in preschool disadvantaged children. Two forms, A and B, are available and it is recommended that one be used as a diagnostic pretest and the other as a progress measure. The test is an individually administered, non-verbal, untimed, but paced instrument. The child responds to questions, given in…

An investigation was designed to ascertain the effects of cultural background on selected intelligence tests and to identify instruments which validly measure intellectual ability with a minimum of cultural bias. A battery of tests, selected for factor analytic study, was administered and replicated at four grade levels to a sample of Metis and…
