I had a small problem with the test.
You can only do this test once every 12 months. I completed it last August as part of the recruitment process for the VA Cadetship. That now means that I have to re-submit my results from last year. In other words, it wouldn't let me actually do the test again - it only let me submit my 2012 answers.
Anybody else have this problem?
EDIT: Here's from FAQ on the test site:
Why can't I complete the recruitment assessments more than once in a 12 month period?
To ensure that all candidates for employment have an equal opportunity to perform and that no-one is over-advantaged by practice, you won't be able to complete a Onetest recruitment assessment again within 12 months.
If you apply for another position with the same organisation, or another organisation, within that 12 month period, you'll be asked to release your previous responses. These will then be compared to the relevant comparison group for the new position, therefore your percentile score may be different from the first time you completed the assessment.
