The national program of bilingualism has caused the need for more EFL teachers in Colombia. This could beseen as an opportunity for graduates from teacher education programs. However, in some private language institutions EFL Teachers with no EFL university-based degree (TNEUD) frequently outnumber teachers who hold it (TEUD). In this article, we will report the findings of an explanatory case study aiming at unveiling the reasons for this phenomenon. Data collection included: documentary analysis, coordinators’ interviews and teachers’ surveys. Three main issues appear to favor the choice for TNEUD: their language proficiency, their teaching methodologies, and an “X factor”. Data analysis suggests that the coordinators (re)interpret the NPB and this leads to discriminatory practices, stereotypes and deskilling of TEUD.
