Yet, the evidence is scarce of possible gender differences among Sudanese students. This study examined possible gender differences in the Wechsler Intelligence Scale for Children 3rd version (WISC-III) scores among Sudanese students by exploring Differential Item Functioning (DIF) across five subtests: picture completion, information, similarities, picture arrangement, and object assembly. The study sample comprised 455 boys and 525 girls aged 6 to 16. The results following a Likelihood-Ratio Test within Item Response Theory, applying the three and 2-parameter logistic models, revealed seventeen items with differential functioning by gender. The girls’ scores were higher on eight items across picture completion, information, similarities, and picture arrangement subtests, and the boys’ scores were higher on nine items across the subsets of picture completion, information, similarities, picture arrangement, and object assembly. These DIF analysis results suggest a need for actions to ensure fairness and equity in the interpretation of scores from the WISC-111 in the Sudanese context.
