The primary aim of this study was to use item response theory (IRT) to develop a revised version of the Arabic Big Five Personality Inventory (ABFPI-30 items) that can be used to assess the big-five personality factors in Arab samples. A convenience sample of Egyptian college students took part in this study (N = 1,418). Results indicate that the scores from the revised version (25 items) highly correlate with the scores from the original version, and the item parameters of the revised version were better than the original version. Furthermore, results from the current study showed that the Test Information Function (TIF) was not significantly lower than the original one. Across the five dimensions of the ABFPI there were trivial differences among the TIF of the original and revised version. It was concluded that the revised ABFPI-25 has good psychometric properties. Because this inventory was written in standard (not slang) Arabic, it would be suitable for assessing personality in any Arab country. Furthermore, its English version deserves a trial with an English-speaking population. Keywords: Big Five, Item response theory, Neuroticism, Extraversion, Agreeableness, Openness, Conscientiousness
