global scale For early development



The Global Scale for Early Development was initiated by the World Health Organization to measure child development for children at birth to age three.  GSED has two scales:


  • A short caregiver report survey that can be administered through surveys that generates population-level estimates of child development
  • A longer scale that includes both direct assessment of children and caregiver reports of child development that can be used for program evaluations.  


Developed through a global consortium of scientists, GSED is now being validated in several countries.  Initial validation will also take place in the United States in 2020, through online surveys.  Once validated, GSED will be open-source and available for use through the World Health Organization.  Read more about GSED here.
