Digital Proficiency Self Assessments for interpretation of slide-based biomarkers in breast and lung cancer

We provide a number of self assessment proficiency tests to be taken in your own time. There allow you to preview the format of our tests and practice with some examples. These tests will always be open.

After each case, you will have an opportunity to see the original clinical diagnosis and distribution of scores from the relevant proficiency testing rounds. There will also be a link to a discussion of each case.

If you provide us with your contact details, we can also send you a record of your results.
