ACE confirmation test is used to confirm the accuracy of a test result. It provides a comparison with the performance on the initial completed ACE test, ensuring that the result is reliable.
ACE confirmation test is given under supervision and can be completed within 15 minutes (on average 7 minutes).
As with ACE, the confirmation test is based on Computer Adaptive Testing (CAT), allowing a precise measurement based on a minimal number of items.
ACE-confirm computes the likelihood that a person’s ACE-test was a valid representation of the person’s true score. You do not an actual score with the ACE-confirm and such a number is not computed or stored anywhere. For example, a likely scenario is that a person, who scored 5 on the ACE-test and then afterwards gets a negative results from the ACE-confirm, will do worse than 5 on a future ACE-test.
If ACE-confirm is positive it means that the person did the same or better than predicted by the first ACE-test. If ACE-confirm suggest a new test and ACE-test is negative, it means that the person did significantly worse than in the original ACE-test.
