What comparative data will it yield?

The direct assessment of children will yield data on the following domains at the start and the end of the year.
  • Early reading
  • Early mathematics
  • Short term memory
  • Physical development
  • Personal, social and emotional development
 
Each of these domains will be related to age, home background, first language and pre-school experience.  This will allow each country's data to be reported in a contextualised fashion.
