The development of students' socio-affective and social skills is part of the general objectives of national curricula (Eurydice, 2018). These are extremely important aspects in the educational context as they are part of students' overall development (Abrahams et al., 2019). In line with these curricular aims, large-scale evaluation programs have begun to include non-cognitive aspects. For example PISA 2015 included collaborative problem solving (OECD, 2017), and in 2018 it included global competence, conceptualized as the capacity to understand others' perspectives and points of view (OECD, 2018, 2019). Educational evaluations with large samples in Latin America have explored socioeconomic factors associated with performance (Murillo & Hernández-Castilla, 2011). In the United States, The National Assessment of Educational Progress includes an adaptation of the Grit Scale (Duckworth et al., 2007). Grit is one of the noncognitive variables that has appeared most often in the literature over the last ten years. It consists of a positive trait based on an individual's perseverance, combined with the passion for achieving a long-term objective (Duckworth et al., 2007). As Duckworth (2016) put it, being gritty is holding on tightly to a meaningful objective, being gritty is falling seven times but getting up eight. Despite the increase in research into grit in the last ten years, results have not been conclusive. One of the most recent debates about grit is whether it should be considered as a general or specific domain (Cormier et al., 2019). Most studies have focused on grit
