This study investigates the potential benefits of serving as a journal reviewer on one’s research productivity. Grounded in constructivist and interpretivist frameworks, a qualitative research design was employed to gain a nuanced understanding of this relationship. Data were collected through semi-structured interviews with six Vietnamese academics experienced in journal reviewing in the field of language studies. The findings revealed that the reviewing process deepens understanding of academic publishing, promotes critical thinking, enhances methodological proficiency, fosters ethical awareness, and cultivates a constructive feedback mindset. Moreover, in the Vietnamese context, benefits such as nurturing a globally competitive mindset, promoting a culture of excellence, and strengthening English language skills were highlighted. These insights suggest that the role of a journal reviewer extends beyond the gatekeeping of academic quality, offering significant potential to boost research productivity. The study underscores the need for greater recognition and support for this crucial role, especially in developing countries like Vietnam.
