The Psychometric Properties of the Raven Intelligence Test (RIT): Insights into Validity, Reliability, Item Difficulty, and Item Discrimination

The research aimed to validate the Raven Intelligence Test (RIT) in the Jordanian context using a sample of 414 students selected from secondary schools in Amman, Jordan aged between 15 and 17 years. The study yielded several findings. Notably, in terms of validity, the study assessed predictive validity through school achievement, concurrent validity using the School and College Ability Test (SCAT), construct validity by comparing scores of normal and gifted students, discrimination power through extreme score differences, and factorial validity via confirmatory factor analysis (CFA). The reliability of the test was evaluated using Cronbach’s (α), split-halves, test-retest method, and the correlation between each item and the total score. We also calculated item difficulty and item discrimination in order to evaluate the quality of the test as well as its ability to discriminate among the intelligence levels. These favorable outcomes provide additional support for the reliability and validity of the test in measuring cognitive abilities which may further prove useful in contexts such as talent identification and recruitment.
