The present study is aims to evaluate the effect of improving micronutrient intake through behavior change communication intervention on nutritional status and academic performance of school age children. Moreover, it may help to prevent or mitigate malnutrition. However to the best knowledge of the authors, BCC intervention using posters, and lecture for school teachers and students have not yet been empirically tested generally in Ethiopia, specifically in the study area context. The present intervention is unique in combining the use of conventional BCC intervention tools, that is, lecture and posters as reminder for intervention reinforcement.
