Child labour is an important aspect of social and economic reality that surrounds us although it is sometimes unnoticed. It is the severe problem of the world in general and the sub-Saharan countries like Ethiopia in particular in which children are considered an asset and means to improve livelihood of their family at the expense of their education. The attempt towards the elimination of child labor in Ethiopia is still lagging compare to the rest world. This in turn is affecting adversely the accumulation of human capital. Thus, the researcher was intended to assess the impact of Child Labour on Children’s Educational Achievement in Ganta Afeshum Woreda and give the possible solution to overcome this problem. To realize this objective, the researcher employed qualitative approach and used in depth interview, FGD, key informant interview, personal observation data collection instruments and employed descriptive research and purposive sampling technique. The researcher analyzed the finding qualitatively through interpretation, description and summarization of the data. As the finding of the study indicates child labour is sever in rural area than urban area and also girls are more exposed for child labour than boys, children are involved in domestic and non-domestic productive activities. The attitude of communities toward child labour is also positive; they consider children as valuable asset for contributing family income. The views of households on working children arise commonly from their poor knowledge about the issue and is directed by traditional outlooks of uprooting ‘milk teeth’, that is seen as a shift from childhood to adulthood. As the finding indicates, Child labour has an impact on children’s educational achievement by making them: repeated the class, absenteeism from class, drop out, make very tired, shortage of times for study and reducing the chance to access education, beside this, as the finding indicate attitude of the communities, employers, poverty coupled with limited access to credit, health and family size as well as the abusive practices are the challenges that hamper eliminating of child labour. Finally, as the finding indicate the local administrator strategy of employing one sector, one children and work with NGOs, private sector and public sectors play significant role via improving the future childhood of children.
