A pilot study of race, ethnic, gender, and parental education level differences on the Naglieri General Ability Tests: Verbal, Nonverbal, and Quantitative

Abstract This study was conducted to examine the relationships between general intelligence test scores and race, ethnicity, gender, and parental education using the Naglieri General Ability Tests: Verbal, Nonverbal and Quantitative (Naglieri & Brulles, & Lansdowne, 2021) for three samples that closely match the U.S. population. Few differences were found on the preliminary versions of the Verbal (Naglieri & Brulles, 2021; N = 2482), Quantitative (Naglieri & Lansdowne, 2021; N = 2369), and Nonverbal (Naglieri, 2021; N = 2383) Naglieri General Ability Tests. These initial findings suggest that this approach to measuring general ability may ultimately have utility for equitable identification of students from diverse backgrounds for possible inclusion in gifted educational programs.
