A summary of the working group discussions on proficiency testing (PT) and external quality assessment (EQA) held at the Eurachem Workshop, Portoro, Slovenia, 9-12 October 2017, is provided. The working groups covered a range of issues concerned with current practice and future directions;the importance of interpretative PT/EQA schemes;changes to PT/EQA schemes in developing countries over the last 10years;implementing ISO/IEC 17043 for sampling PT/EQA schemes;traditional versus virtual PT/EQA items;experience of the implementation of EA-4/18;and use and treatment of measurement uncertainty in PT/EQA schemes. Delegates from fifty-two countries attended the workshop, and this diversity of different backgrounds was represented on each of the working groups to capture a range of views and experience from a number of different measurement sectors. Working group representatives included PT/EQA providers, participants in PT/EQA schemes, end users of PT/EQA results such as accreditation bodies and regulatory authorities, national measurement institutes, laboratory associations, suppliers, universities and independent consultants from countries around the world.
