... Although the 4PL model was introduced more than three decades ago, it encounters a number of theoretical and practical hurdles which make it less attention, less explored, and less widely used than the other three IRT models and Rasch model. One of the theoretical and practical obstacles to the 4PL model is shown by the Barton and Lord's (1981) study which shows that setting the upper asymptote parameter values to be not equal to 1, which in this study set the upper asymptote values to be 0.99 and 0.98, it turns out that in general did not show a change in the examinee's ability estimate compared to when the upper asymptote parameter was made equal to 1 (i.e., 3PL model); later Primi et al.'s (2018) study also found the similar results. Because of the study results they obtained, they suggested that the 4PL model should not be urgent to use, moreover due to the limitations of available technology, it takes a lot of time to perform complex computations and derivations, and it is also difficult to estimate the parameter, as pointed out by several studies (e.g., Kalkan, 2022;Kalkan & Çuhadar, 2020;Liao et al., 2012;Loken & Rulison, 2010) based on the extant literature, when working with this model. ...

... Creativity is one of the skills needed in the 21st Century (Nakano & Wechsler, 2018). Creativity is not only needed in education but also plays an essential role in the economic growth of a country (Sharma & Sharma, 2018). ...

... Ao centralizar a escola como equalizadora social para países desenvolvidos e em desenvolvimento (31), o conceito das competências necessárias para a formação integral do estudante passa a protagonizar pesquisas para mensuração de resultados escolares e, por consequência, subsídios para a criação de política públicas que promovam a equidade de oportunidades (26,31,35,39,44,45). ...

... The results of current study provide evidence that there are sex differences in performance on few test items in SPM test. The differences in cognitive abilities between the two sexes have always been a subject of investigation for researchers (Wechsler et al, 2014). The differences between the sexes in Raven's Matrices tests have always been among the most interesting, most controversial subjects; and yet, the studies have not reached a clear conclusive result (Yang et al, 2014). ...
