In terms of assessing a child's developmental abilities, what age group first comes to mind? Often, early childhood educators begin thinking about developmental assessments when children are between the ages of 3 and 5. However, they need to be cognizant of the fact that child development begins from the moment a child is born. It is, therefore, their responsibility as early childhood professionals to begin examining and assessing children's growth and development from the very moment they are placed in their care; this can happen as early as 6 weeks of age. In this article, the authors provide a framework of the five domains of development and highlight which areas to focus on when assessing infants (0-12 months).
