Abstract

Differential Item Functioning (DIF) has been severally studied by psychologists to measure testees performance on test items based on their differences. This paper therefore investigated the Differential Item Functioning (DIF) of testees (pupils) age 7 approximately in the Wechsler Preschool and Primary Scale of Intelligence (WPPSI-IV). Sample was drawn from the population. The sample size of pupils was 512 cut across three ethnic tribes. WPPSI-IV while IRT software (R) was used for data analysis. Findings from the study showed that 145 items function differently, while 125 items did not show bias. It was recommended that testees' interests, beliefs etc. should be taken into consideration during test construction so as to place the children on equal level playground and that the preschool curriculum should be modified to take care of the differences in testees.
