Abstract INTRODUCTION UK Public Health Register (UKPHR) provides a regulatory home for the public health workforce, protecting the public through workforce development and governance. We work with PHE on changes to reflect the revised Public Health Skills & Knowledge Framework (PHSKF) and PHE's Fit for the Future report.METHODThree themes encompass our joint working:Introducing revalidation;A new portfolio equivalence route to register for public health specialists; andRevising practitioner registration with help from PHE and Health Education England (HEE).RESULTSWe consulted on and finalised a revalidation scheme. Professional appraisal is at the heart of the new scheme, which we will pilot before full introduction from 2018.We are consulting on a new portfolio route to registration for public health specialists. We worked jointly with the Faculty of Public Health to address PHE's recommendation for a route to specialist registration for senior, experienced local authority managers and their peers.We are reviewing practitioner registration, working with HEE on the intended roll-out of practitioner registration England-wide.For public health employers and commissioners of public health services, registration gives assurance of registrants' competence. CONCLUSIONRevision of PHSKF is driving changes in recruitment and development of the public health workforce. Ongoing developments, including a digital service for users of PHSKF, will enable the public health system as a whole to extract optimum value from the investment in PHSKF.
