The study was conducted to find out: (1) the efficiency of area differential index procedure for the 3- parameter Logistic model, and M-H method on detecting a gender-related differential item functioning of a spatial ability scale. (2) The agreement between the area differential index procedure for the 3- parameter Logistic model, and M-H method on detecting a gender-related differential item functioning of a spatial ability scale. The test Sample consisted of 1000 males and females tenth grade students in Jordan (500 male and 500 female). The study revealed that: (1) the agreement between the two methods was convergent, (2) the efficiency of the two methods wss 75% for M-H method,, and 45% for area differential index procedure for the 3- parameter Logistic model, and (3) males outperform females in spatial ability
