Assessment of Development in Children
The development of  a child  is studied through various responses which he exhibits following a natural or experimental stimulus. Basically the child development could be studied  in two ways.
i)  Through Observations: Behaviour  of  children  is  recorded  through observations in relation to natural environment.
ii)  Through Experimental Methods: Experiments are designed  to elicit and record a behaviour response to a particular stimulus.
Developmental assessment  can be divided into four  areas:  gross motor,  fine motor,  adaptive language and personal social behaviour. You  have learnt the developmental milestones of children in various age groups.
