Shadow education, private tutoring outside mainstream schooling, has expanded exponentially in India since the 1990s. This tutoring aims to give students an edge in competitive exams for limited university seats. Though historically present, its scale has fueled equity concerns. This chapter analyzes the forces driving growth and their implications on finances, disparities, learning, student welfare, and public schooling. Quantitative evidence shows the stunning rise in prevalence and spending, from cities to rural India. Competitive exams, mobility aspirations, and dissatisfaction with public education propel demand. The chapter highlights financial burdens, including families incurring debt, and access inequalities across socioeconomic, geographic, gender and caste lines. Learning outcomes remain contested, with risks of teaching to the test. Tutoring's relationship with student stress and public school quality is complex. While bans face hurdles, regulatory options have tradeoffs. Further research on long-term impacts is imperative.
