The earlier the child takes the test, the better it is due to the higher mould-ability in the characters of young children.  Also, at a younger age, it will be easy to set the foundations for children and all efforts and resources can be channelled towards a particular aspect of the child’s development at an early stage.  Especially for talent development, the earlier the child starts, the easier it is to get a headstart over other children.  This is especially in the case of sportspersons, whose peaks are usually expected when they hit the age of twenties.
