We recognise that regular quality control assessments are crucial to ensure a high quality output of phytoplankton data. Accreditation of this Proficiency Testing scheme under ISO 17043 is programmed for 2022. All our work is carried out following, and to the technical and managerial standard requirements for PT schemes (ISO17043). The data is statistically analysed using the statistical methods as laid out in ISO13528 ‘Statistical methods for use in PT by interlaboratory comparisons’. We use the statistical database software ProLab Plus from QuoData to do the statistical evaluation of the participants’ data.
