BACKGROUND:
The COVID-19 pandemic highlighted underinvestment in global public health workforce capability (1,2). In response, the World Health Organisation (WHO) and partners set out a roadmap to strengthen the global public health workforce's capacity to deliver Essential Public Health Functions (EPHF) (3). The UK Faculty of Public Health (FPH) Global Health Committee (4), working through a Memorandum of Understanding (MoU) with WHO, initiated a co-ordinated policy approach that supports competency-based education and training (CBET) for public health globally.

METHODS:
A package of FPH assets was created that demonstrate UK CBET for Public Health to enable relevant FPH Special Interest Groups (SIGs) working with other countries to reference and adapt the UK approach. This included a slide deck and infographic, complemented by case studies shaped through several key informant interviews, and dissemination webinars. Under the FPH–WHO MoU, we also established a roster of temporary advisers to provide structured practical support to WHO roll-out of the EPHF workforce roadmap. The experience was synthesised and used to inform a FPH Global Education and Training policy. The policy will be further developed based on learning from implementation.

RESULTS:
The paper provides a summary of lessons and feedback on: the package of CBET assets; the induction package for the temporary advisors; the experience of several SIGs that engaged in the FPH WHO roster of temporary advisors; and feedback from WHO and countries on the assistance in a variety of areas of workforce development and EPHF implementation. Factors that contributed to successful collaboration between countries and temporary advisors will be showcased.

CONCLUSIONS:
The paper will highlight the success of the FPH project on global education and training, and the partnership formed between the FPH and WHO in developing the global public health workforce. Lessons will be used to inform future, similar partnerships with WHO.
