“…Its detractors, on the other hand, maintain that the conditions that arose in the early 1980s, in which the Catalan language found itself in a position of clear inferiority, have changed, and that parents have the right to school their children in the language of their preference (UNESCO, 2016;Coll, 2018); that immersion prevents students from being schooled in their mother tongue, which could affect their academic performance (AEB, 2017); that immersion is being used for political reasons in order to promote the Catalan national identity and to the detriment of the feeling of belonging to Spain (Oller et al, 2021); and that there is no updated and comparable evidence about the level of Spanish language of Catalan students (Convivencia Cívica Catalana, 2016). Moreover, Oller et al (2021) show that the immersion policy clashes with the preferences of the Catalan society, where a bilingual (Spanish-Catalan balanced) or even trilingual (incorporating subjects in English) education system is preferred to the current monolingual system. As Clua (2017: 41) describes, "to teach in Catalan or in Spanish is a sensitive political issue that goes far beyond considerations about linguistic competencies in a bilingual context".…”
