Studies to date show how low-fee private (LFP) schools, including unrecognised ones, have gained practical legitimacy and continue to increase in number. However, little explanation is offered regarding the legal legitimacy of such unrecognised LFP schools. This paper intends to fill this gap by examining the legal legitimacy of unrecognised schools in Delhi whose actual existence was challenged by the Delhi High Court and the Right to Education Act, 2009. The paper also illustrates the practical legitimacy of unrecognised schools by comparing perspectives of different actors (the government, NGOs and managers, teachers and parents at nine unrecognised schools in Delhi) based primarily on the author's interviews with these actors.
