The services aim to cover children of 0-6 years of age in rural areas and urban slums in addition to children enrolled in classes 1st to 12th in Government and Government aided Schools. It is expected that these services will reach to about 27 crores children in a phased manner. The broad category of age group is as shown below in the table. The children have been grouped in to three categories owing to the fact that different sets of tools would be used and also different set of conditions could be prioritized.
