Academic and occupational guidance of the 9th graders require a valid and reliable instrument. Given that Barrett Aptitude Test is widely available, and perhaps used, it was deemed necessary to assess its psychometric characteristics. To this end, a cluster sample of 830 ninth graders from among all such students during the 2017-2018 school year in cities of Saqqez and Bukan, was selected. They answered the 434 questions on the aptitude test in 153 minutes. Data analyses revealed that both validity and reliability of the instrument are to some extent acceptable. Thus it can be used in guiding the 9th graders as well as estimating their IQ based on the scores obtained through this test.
