Recent quantitative research on bilingual education suggests beneficial academic outcomes for pupils regardless of socio-economic status (SES). Bilingual education in England, a relatively novel phenomenon, may be better understood from teachers’ perspectives; however, there is a paucity of qualitative research in this area. To fill the gap, the present study explores the unique perspective of a sample of bilingual schoolteachers regarding the children who attend bilingual schools and the effects of bilingual education on children’s academic and non-academic development. Semi-structured interviews were conducted with six bilingual schoolteachers, and thematic analysis was adopted to interpret their experiences in greater depth. A thematic analysis revealed four superordinate themes: Academic and Socio-Cultural Effects, Privilege in Bilingual Education, Bilingual Education Takes Time, and Special Educational Needs. These results highlight academic, socio-cultural, and linguistic benefits with important implications for promoting equity in bilingual education. Further research should focus on schools with a higher proportion of students from lower socio-economic status backgrounds.
