Abstrak: Children were source of potentials and next fighter of nation’s ideal. Thus, they need to get chance to normally growth and develop as wide as possible (BPS 2001). This research was aimed to obtain information about performance of nutritional status, food consumption, contribution of food in school, and also sufficiency level of energy and nutrients of children of Sekolah Alam Bogor and SDIT Insantama in 2010. Data for this research was taken from research entitled “Analysis of Food Management in Elementary School and Menu Quality of Student in School” (Reisi Nurdiani 2010). Sekolah Alam Bogor has modus of age distribution at 11 years (43.48%) and SDIT Insantama at 10 years (40.00%). Age distribution of both schools wasn’t significantly (p>0.05) different.
