Abstract: Successful participation in Proficiency Testing/Interlaboratory Comparison (PT/ILC) schemes is a method to ensure validity of results for any laboratory. It is also a component of a complex of means for demonstrating technical competence of a laboratory as an organization. The new accreditation standard ISO 17043 for PT providers together with the newly updated ILAC Policy of PT participation introduce a different perspective on the activity of PT provider in regard to quality assurance. Technical and management requirements from the ISO 17043:2023 that are essential for a competent activity of PT/provider are identified with a rationale for their increased importance. This importance is related both to the practical impact on the PT/ILC providers’ customers (laboratories) activity and laboratory benefits of participation in PT/ILS schemes besides the traditional qualitative and quantitative interpretation of their participation. Identified requirements are accompanied by a practical and explained potential implementation strategy which is aligned with the ILAC Policy on PT/ILC participation. Successful implementation of the essential requirements of the ISO 17043:2023 is a necessary step for any PT/ILC provider that seeks credibility on the proficiency testing market. Such implementation may also be an important step towards full implementation of the ISO 17043:2023 and achieving accreditation thus benefiting from full confidence in the activities of the provider.
