I wish to participate in a proficiency test. When should I register?

You may register at any time during the year, as long as tests are available. Note that it is necessary to have registered about three weeks before test samples are sent (instructions are sent prior to the sample distribution and the list of participants is then closed).

For a first registration, fill in the registration form.
