Private supplementary tutoring has long existed in Bangladesh, as elsewhere in the world, but in recent decades has become much more visible. Much tutoring 'shadows' or reproduces formal schooling as fee-based academic teaching outside school hours. This paper focuses on school factors that shape demand for private supplementary tutoring in English at the secondary level, drawing on data gained from both quantitative and qualitative methods. The paper is especially concerned with urban and rural variations, noting that rates of tutoring are greater in urban areas but that many factors converge to create similarities. Private tutoring in English is highly demanded because English is a compulsory course; and in addition to being a subject in its own right, it assists in the learning of other subjects. While private tutoring may support the academic learning of some pupils, it also has problematic dimensions. As such, the spread of tutoring across urban and rural areas is not necessarily to be welcomed.
