Background:-Malnutrition, temporary hunger, poor health condition and socioeconomic status of parents are among the many reasons for underperformance of children in school. School feeding program has been implemented in many countries in order to make students concentrate in their academic exercise. The government of Ethiopian in collaboration with development partners is piloting school feeding program in selected food insecure areas of the country. The effectiveness of the program is not yet evaluated. Objective: - The objective of this study was to assess the impact of school feeding program on nutritional status and academic performance of children in the selected schools Arada sub city, Addis Ababa, Ethiopia. Methods: - A School based cross sectional and comparative perspective cohort study was conducted in 4 randomly selected schools. Over all 234 primary students participated in the study. The students are randomly assigned for intervention (N=117) and control (N=117). The students were assessed for socio-demographic characteristics, biochemical test, dietary diversity score (DDS), food intake and anthropometric measurements. DDS and adequacy of food intake were determined using meal served for five consecutive days. All other parameters were assessed before and after the intervention as well as at six months for both the intervention and control group. The data were before and after the intervention and against the control group. Nutritional status was calculated using WHO (2007 growth standard. Result: -. The percentage of anemic students in fed and non-school fed groups before intervention was 35.5% and 38.5% respectively. Anemia has reduced to 18.9% and 35.5% for school fed and non-school fed group respectively after intervention. The reduction of anemia in the intervention group is significant (p
