Although most of the world's disabled people live in developing countries, little is known about the consequences of disability in this part of the world. Using the DHS-MICS 2011 data of Cameroon, this paper contributes to the literature by providing new robust estimates of the effect of child disability on education in a developing country context. It controls for unobserved heterogeneity within the households by using a 'true' sibling fixed effect model and also accounts for the severity of disability. The results show that moderate and severe disabilities reduce the probability that a child attends school and diminish school progress.
