This case study examines a Chinese and Korean-Chinese pre-service teachers' perceptions of their mentor teachers' role in supporting inclusive practicum experiences in USA elementary school contexts. The findings demonstrate that a mentor teacher's open conversations and willingness to host those students bring positive influence on their learning and growth. The findings also indicate that the facilitative roles of mentor teachers in the promotion of inclusive environments are intersected with the socio-cultural and political contexts of practicum schools and universities. The study concludes with implications for enhancing the inclusion of diverse pre-service teachers through collaborative roles of multiple practicum stakeholders, including pre-service teachers, mentor teachers, practicum schools, and universities.
