Who this is for:Analysts across the Government Statistical Service (GSS) working with administrative data

The Administrative Data Quality Framework (ADQF) was developed by the Methodological Research Hub and the Data Quality Hub. Both teams are based in the Methods and Quality directorate of the Office for National Statistics (ONS).

You can access the latest version of the ONS Administrative Data Quality Framework (ADQF) on GitHub.

About the framework

The framework aims to help you assess the quality of administrative data for use in the production of statistics. It describes:

  • quality dimensions for assessing input quality, or quality dimensions for data
  • output quality, or quality dimensions for statistics

The framework also gives guidance for using these. The framework is consistent with the Code of Practice for Statistics and its associated Quality Assurance of Administrative Data (QAAD) standard and toolkit.

This is an ongoing piece of work with further planned developments. We will continue updating it with useful guidance, methods, metrics, and links to other tools as they are developed.
