the process of converting the child’s testing and observation data into numerical indicators or percentages in order to compare the child’s results with age norms. This type of assessment allows cognitive, sensory, motor and emotional abilities to be accurately and systematically measured, contributing to a clear and objective identification of the child’s strengths and weaknesses. Quantification is also used to track the evolution of outcomes, whether after therapeutic or educational interventions, to identify improvements or the need for adjustments to strategies. Quantification is also a tool for consolidating information from multiple tests, making it easier to analyze them and generate a comprehensive and reliable diagnostic report. Such an assessment usually includes the use of normative indicators, standardized tests and age comparison tables, which make it possible to assess the relative results of the child within the normal group. This provides a scientific basis for decision-making on appropriate interventions and individualized support plans.
