WHO-Listed Authority (WLA)

The GBT remains the foundation for classifying regulatory systems according to maturity level, providing a structured approach to assessing how well a regulatory system is configured to achieve desired results. The WLA performance evaluation framework provides a more detailed picture of how a regulatory system operates through an extended set of measurements targeting key regulatory outputs and consistent adherence to international standards and good regulatory practices.

As set out in the Policy, regulatory authorities that have attained an overall maturity level 3 classification are eligible for consideration as a WLA. In addition, following public consultation on the draft WLA Operational Guidance and discussions with Member States, transitional arrangements were developed that afford all regulatory authorities on the public WHO Interim list of National Regulatory Authorities the opportunity to be considered for WLA evaluation and listing - as reflected by their placement on a list of transitional WLAs (tWLAs). 

The tWLA list replaces the WHO Interim list, which compiled categories of authorities recognized by WHO to have achieved levels of operation necessary for the regulation of medicines and/or vaccines. The tWLA list is valid for five years from the date of publication of the interim WLA Operational Guidance (31 March 2022) during which time the authorities will be evaluated against the requirements for designation as a WLA. A regulatory authority will move from the tWLA list to the permanent WLA list upon successful completion of the WLA evaluation process.

To ensure impartiality and transparency of the WLA decision-making process, the WHO Technical Advisory Group on WHO Listed Authorities (TAG-WLA) has been established. The TAG-WLA acts as an advisory body to WHO, by rendering an opinion on the listing/delisting of regulatory authorities as result of the WLA evaluation process.

WHO will adopt a pragmatic and risk-based approach to evaluating performance that considers existing information and experience to ensure optimal use of resources and the efficiency of the process.

WHO will also be publishing additional documents and information related to the implementation of the WLA framework.

Note: The ultimate responsibility and decision for use of tWLA and WLA lists resides with the users (e.g., regulatory authorities, procurement agencies) and will depend on the specific context of its intended use. In no event shall the World Health Organization be liable for any damages arising from its use.
