This paper uses a survey of 15,000 households and 260 tutors to fully characterize 21 distinct education markets in Pakistan. Roughly 30% of students receive daily private tutoring, making it a major potential vehicle for scaling educational best practices. Moreover, most paid employment for women with secondary degrees in these markets was private tutoring—cultural constraints limit women’s work opportunities, and tutoring is one of the highest-paid activities women can perform from home. This has led to tutor markets where many suppliers offer group-based tutoring in their homes after school. However, follow-up surveys and pilot work show that, while the market may be pervasive, it is not always visible - parents are often unaware of alternative tutor options for their child. We are currently studying how addressing this information failure affects both the supply and demand sides of the tutor market.
