In 2026 IRTA, Spain in collaboration with the IOC Science and Communication Centre for Harmful Algae, Denmark will conduct a proficiency test on marine phytoplankton abundance and composition amongst laboratories.

The IPI proficiency testing scheme is open for participation to all relevant laboratories globally. This test is divided into two main competency areas and each participant must complete both to obtain the required certification:

1. Taxonomy knowledge assessment: marine phytoplankton (HAB) taxonomy online quiz hosted by IOC’s Ocean Teacher Global Academy (OTGA)
2. Sample Abundance and Composition: analysis of water samples sent to the participating laboratories comprising several Phytoplankton species which analysts must identify and enumerate.

Registration opens on 01.01.2026 and closes on 28.02.2026
Samples sent to analysts + Taxonomy knowledge assessment (online HAB quiz in ‘Ocean Teacher’) opens: 01.06.2026
Deadline for submission of samples and online test results to lead laboratory: 01.09.2026
Intercalibration Report and Workshop: December 2026
