At Kiaan Children’s Hospital, we recognize the importance of developmental assessment, which involves evaluating a child’s performance in relation to their peers of similar age. This comparison is made using a representative sample from the child’s population group. Multiple factors contribute to significant variations in performance across different population groups. In a multicultural society, it can be particularly challenging to establish appropriate benchmarks for developmental standards. This article aims to provide an overview of the literature on child development assessment, shedding light on normal developmental parameters, guidelines for assessing a child, and determining when a specialist assessment is necessary. Our goal is to ensure comprehensive support for children and their families throughout their developmental journey.
