Background: School age children (SAC) are vulnerable to malnutrition which can have adverse effects on their academic performance at school. Micronutrient deficiency affects as many as two billion people in the world. About 250 million people out of this suffer from deficiencies of iron, vitamin A, zinc and iodine are children. Malnutrition or micronutrient deficiencies lead to lower enrolment and completion rates. A nutrition behavior change strategy provides individuals with the necessary resources, knowledge, skills, motivation and reinforcement needed to encourage positive change in health behavior. So far, there are no any studies in the context of the study area in particular and in the country in general on the effect of behavior change communication (BCC) on improving the nutritional status, micronutrient intake and academic performance of school age children.
