The present paper examines initial teacher education (ITE) students’ sexual orientations and the intersections of students’ sexualities, socio-demographic backgrounds and career motivations. The findings reveal that although LGBT people experience considerable covert and overt social, institutional and religious barriers when applying for and entering ITE programmes in Ireland, they are highly motivated and committed to a teaching career. Their strong desire to change the of young people, together with their personal experiences of schooling uniquely position them to challenge and disrupt heteronormativity and sexual discrimination in schools and in ITE.
