"In recognizing the need for a set of questions that would produce internationally comparable data on children, the Washington Group formed a subgroup in 2009 that is chaired by the National Statistical Office of Italy (ISTAT). UNICEF joined the subgroup in 2011.
The first main activity of the subgroup was the development of a short set of questions to reflect current thinking on child functioning for inclusion in censuses and surveys. The new module uses the ICF-CY as the conceptual framework and relies on a functional approach to measuring disability.
The Washington Group/UNICEF Module on Child Functioning, finalized in 2016, covers children between 2 and 17 years of age and assesses functional difficulties in different domains including hearing, vision, communication/comprehension, learning, mobility and emotions. To better reflect the degree of functional difficulty, each area is assessed against a rating scale. The purpose is to identify the subpopulation of children who are at greater risk than other children of the same age or who are experiencing limited participation in an unaccommodating environment. The set of questions is intended for use in national household surveys and censuses"
The module is being translated into multiple languages. Supporting documentation, including a concept note, tabulation plan, templates for reporting, guidelines for interviewers and training materials are also available.
