Abstract
Background The value of competency frameworks for developing the public health workforce is widely acknowledged internationally. However, there is a lack of formal evaluations of such frameworks. In the UK, the Public Health Skills and Knowledge Framework (PHSKF) is a key tool for the public health workforce across the UK, and this study presents the evaluation of the PHSKF 2016 version, with the aim of reflecting on implications for international public health competency frameworks. Methods A sequential explanatory design was employed. An online survey (n = 298) was completed with stakeholders across the four UK nations and different sectors. This was followed by 18 telephone interviews with stakeholders and survey completers. Quantitative results were analysed descriptively; qualitative transcripts were analysed with thematic analysis. Results Most respondents had used the PHSKF occasionally or rarely, and most users found it useful (87%) and easy to use (82%). Main purposes of use included team/workforce development (e.g. setting of standards) and professional development (e.g. identify professional development opportunities). Some positive experiences emerged of uses of the PHSKF to support organisational redevelopments. However, 23% of respondents had never used the framework. Areas for improvement included greater clarity on purpose and audience, the need for more support from employers and for clear career progression opportunities, and stronger links with other competency frameworks. Conclusions The development of a digital version of the PHSKF, together with improving buy-in from the workforce and employers could make an important contribution towards UK public health workforce development. Further evaluation and shared learning internationally of the implementation of public health competency frameworks would support global public health workforce development.
