Timetable & scheme

Timetable 2025

WEPAL-QUASIMEME proficiency tests follows an annual timetable. This timetable allows all participants to incorporate the test materials into their ongoing analytical programme. This is particularly important for those participants who need to undertake their QA analysis alongside their environmental samples in the laboratory or at sea.

For the aquatic programmes (coded AQ), registration of participants must be completed by January 15th for Round 1, and by May 1st for Round 2, each year. Later registration for AQ is possible; however, there may not be enough samples available, and your registration may be declined.

Samples for the schemes ISE, IPE, SETOC, MARSEP and BIMEP are sent by post a few weeks before the
start date of the period. Samples for the schemes MS, AQ and BT are sent by courier in the first week of the period. Samples for the schemes FW are sent by courier on pre-determined dates. Participants that receive samples by courier will be notified of the exact date of dispatch.

The deadlines for submission of data are fixed. Any data received after the deadline may not be included in the assessment. A confidential individual laboratory report, the full study report and the electronic summary files will be provided after the deadline for the submission of data. These reports and summary files will also be provided for data received after the report is issued, but the individual laboratory report will include the statement, “Data received after the report was issued.”
