Preliminary information on the Proficiency Test Phytoplankton 2025/ 2026

In phase 6 we will sort all results and publish the preliminary results on our website. Please note that this is a preliminary analysis and may still be subject to change! In this phase, each participant has the opportunity to verify the data they submitted. If there are obvious errors/discrepancies, please contact us. At this stage, no changes can be made to the result values themselves. Rather, the aim is to ensure that we have correctly allocated the data and results. The phase is expected to end on 31.3.2026, after which we will start producing the certificates.
