“…Testing, as mentioned above, is one of those areas that has become a cornerstone in language education (Tsang, Katz, & Stack, 2008;Heilig, 2011;Gutiérrez Eugenio & Saville, 2017), considering both its benefits and drawbacks (Bracey, 2009;Fitchett & Heafner, 2010;Howie, 2012;Koretz, 2016). Language testing is currently used to take decisions in student mobility, student's acceptance in bilingual higher education programs and also to assess language programs (Mahon, 2006;Wright & Choi, 2006;Solano-Flores & Li, 2013;Hill & McNamara, 2015). However, although large scale national assessments tend to be more and more common, they also tend to ignore the relationship between the candidates' personal factors and their grades in high stakes exams (Qian, 2009;Gorges & Kandler, 2012;Bai, Hudson, Millwater, & Tones, 2013) mostly because a great disparity may evidence that practice is not adequate or that socioeconomic problems may be creating significant differences within a country (Fitchett & Heafner, 2010;Kim, 2011;Solano-Flores & Li, 2013).…”
