If you have filtered candidates by score ( Points not percentage) on a test, the system may sometimes display what appears to be a candidate that doesn't fit the parameters. Please see the image below:
We can see that Jakub ( At the top ) doesn't fit the parameters of the test score result. The reason is that he has taken multiple tests with us and a previous test had a score that matches the search result.
In this instance, there would need to be an extra search critea entered, for example 'Test taken' this would then provide the desired results.
