Description: Features: All new normative data were collected to ensure proper representation of demographic changes in the U.S. population. Stratification variables include the four geographic regions in which subjects reside, their gender, race and ethnicity, parental education, and family/household socioeconomic status. Potential bias in test items related to gender, ethnicity, disability, and race is analyzed. Additional test reliability and validity is offered for the entire normative sample and also for specific subgroups of the sample to account for cognitive ability, race, ethnicity, and gender. Each test item was reevaluated using both item analytic techniques and differential item functioning analyses. Floor effects have been eliminated. Verbal and pantomime directions are provided. In addition to English, included are instructions in seven other major foreign languages: Spanish, French, German, Chinese, Vietnamese, Korean, and Tagalog. The Test of Nonverbal Intelligence – Fourth Edition is a practical, easy-to-use, norm-referenced instrument that measures an individual’s intelligence. The administration and response format are pragmatic with simple oral instructions, requiring test takers to answer only with simple but meaningful gestures such as pointing, nodding, or blinking.
