This research has been carried out with the aim of study psychometric properties of Sampad’s Entrance Tests using Rasch measurement model. In this study, answer sheets of 2872 students(1542 boys and 1330 girls) were selected by means of multistage random sampling. The data were analysed using the unidimensional Rasch simple logistic model with Winsteps software . The results revealed that all items of the test showed good model–data fit. The range of items location parameter were -2.48 to 1.83. Also the showed that targeting is not good. On the whole, the findings of this research showed that the Sampad’s Entrance Test does not have good measurement qualities, so should not be used to select students for Talent middle schools.
