Religious minority schools are seen to take on the task of transmitting the normative image of a community, its ideology and culture. Through pedagogy and daily routine practices, schools seek to shape students' ideas of a religion and ways in which it is to be performed. This paper, based on ethnography of a Sikh school in Delhi, explores such schooling spaces and practices that attempt to establish and promote a homogenous religious identity among students. The school rules make it mandatory for Sikh students to adhere to the Sikh identity that it supports. However, interviews reveal that they interpret the religion differently from what is being projected to them through the school's pedagogy. The meaning-making process in the school is complex because while this is a religious institution, it caters to students from other faiths as well. The article argues that religious schools often overlook the diversity of beliefs among students and educational ethnographies can be helpful to explore such institutionalised practices and students' agency in identity formation.
