The field of English Language Teaching (ELT) play a leading role in improving Diversity, Equity, and Inclusion (DEI) in educational settings against the growing global diversity. This paper underlines how DEI is important in ELT and shows how these inclusive teaching practices enhance students' engagement and promote understanding among cultures, thereby helping to get more equitable learning environments. It also critically explores how DEI principles might be more effectively embedded within the ELT curricula, teacher training, and classroom interactions to better meet the needs of an increasingly diverse student population. Data were gathered from a sample of 12 English language teachers via semi-structured interviews in order to explore their current practices, challenges, and successes with DEI. These results demonstrate the fact that, while teachers recognize the importance of DEI, large differences exist among teachers in understanding and practicing DEI. A majority of the teachers reported the use of culturally responsive teaching strategies and using materials that reflect diversity of perspectives to establish an inclusive classroom environment. However, numerous challenges were often emphasized, including limited resources, the complexity of addressing students' diverse language proficiencies, and inadequate institutional support. Notable successes were observed in heightened student engagement, especially among marginalized and underrepresented groups, in the cases where DEI principles were given priority. The study highlights the necessity for more focused professional development and stronger institutional systems to effectively assist teachers in DEI practices. These findings suggest a partial merit in the current valuations of DEI in ELT; however, there remains a need for more comprehensive support systems to ensure equitable and inclusive language learning environments.
