Children living in urban slums in Dhaka, Bangladesh, often have poor access to school and attend different types of school than students from middle class households. This paper asks whether their experiences in school also disadvantage them further in terms of their learning outcomes and the likelihood of dropping out. It is based on interviews with 36 students aged 11-16 from both slum and middle-class backgrounds, in 2012. The paper discusses how these experiences in school are likely to heighten the risk of dropping out for slum students, analyses the results in terms of de-facto privatization and school accountability, and recommends better regulation of private tuition, and teaching styles that are less obsessed with examination results.
