Children belonging to disadvantaged groups are defined at 2(d). These include children from SC/ST, and other socially and educationally backward categories based on cultural, economical, social, geographical, linguistic, gender or other categories that the appropriate governments can separately notify. Appropriate governments can for example notify different categories in different districts and sub-districts of the state, educationally backward religious communities, for example as identified by the Sachar Committee and so on. Weaker sections as defined at 2(e) are children belonging to weaker economic categories that the appropriate governments have to notify, based on a minimum annual income of the parents/guardians.
