Antecedents: Educators’ pivotal role in reshaping interculturality within the English classroom can serve as a potential antidote to the prevailing intolerance and violence in the country. This study investigates English teachers' perceptions of interculturality within the context of foreign language instruction and its impact on the intercultural development of students in a private high school in Colombia. Methodology: Adopting a qualitative paradigm, the study employs a multifaceted approach encompassing semi-structured interviews, reflective journals, and interactive techniques to access the complex dimensions of interculturality. The ensuing data analysis engages in a rigorous theoretical and analytical coding process, culminating in the identification of overarching themes that underpin the study's findings. Results: Among the principal findings, this study shows that educators conceptualize interculturality through a prism rooted in principles of fairness, equity, equality, and respect. Furthermore, the school environment emerges as a pivotal crucible for intercultural experiences, albeit marked by discernible disparities when contrasted with the broader external world. Conclusions: Drawn from this investigation underscore a significant alignment between teachers' intercultural conceptions and Walsh's seminal intercultural principles. Moreover, they accentuate the indispensable role that educators occupy as catalysts for interculturality, underscoring the imperative of comprehensive professional development to effectively impart intercultural perspectives. Ultimately, this study accentuates the ongoing critical discourse engendered among both students and teachers concerning the transformative potential of interculturality within the nation.
