This article is based on qualitative research conducted in Delhi between May 2019 and October 2019 with children from the Salaam Baalak Trust (SBT) as part of a PhD. Data were collected from 30 children in focus group discussions using participatory methods, followed by semi-structured interviews. As the research was conducted among a vulnerable population (migrant street children), every effort was made to conduct the study ethically, including obtaining informed consent and upholding confidentially and anonymity. Careful consideration was given as (...) to how to tackle sensitive issues should they arise during data collection. The children agreed that the interim findings of the research would be shared with them through SBT. In addition, the researcher considered her position in the research and applied a reflexive approach to address ethical issues as they emerged. This article sets out the ethical principles applied in this research and the process followed to uphold each principle during data collection, taking into account the vulnerability of the group being studied and the context of the study (India).
