This PedsCases note provides the most updated developmental milestones chart for school age children. The following resource was developed by Dr. Cara Dosman, a Developmental Pediatrician at the University of Alberta, with local and national colleagues.

HOW TO USE the ‘Crucial skills’ Developmental Attainments Chart:

‘Crucial skills’ is a chart of typical/normal/expected development (according to cultural norms) that can be used to: 1) learn typical sequences of development; 2) guide parents in supporting development; and 3) assist in monitoring development informally. Skills are placed at the ‘oldest’ age of attainment (based on references with level of evidence cited). If a child does not yet show the skills in their age row, they might have a developmental delay (‘possible developmental delay’). This chart is not a standardized developmental assessment tool and 'possible developmental delay' is more accurately identified by the use of standardized developmental screening instruments. Developmental delays are confirmed through formal evaluation by allied health professionals. Please note that there are many influences on child development. Therefore, there are many possible reasons why a child may not yet show a ‘crucial skill’ at their age (i.e. skills in other sectors and context). Children with ‘possible developmental delay’ (identified by screening and/or informal surveillance) need further support and evaluation, such as: 1) referrals; 2) parenting guidance; and 3) health/etiologic investigations and management, as appropriate.
