Correct answers step the candidate up a level, a miss steps them back down and re-checks, so the test converges on their real ability.

Read storyGet a walkthrough shaped around your roles, volume and tools.
Item difficulty adjusts to the previous answer, so a strong candidate moves up quickly and a struggling one isn't dragged through twenty questions they can't answer.
Scores are placed on a common difficulty scale rather than a raw count correct, so two candidates who saw different items are still directly comparable.
Duration depends on the question banks, time limit and stopping rules you configure. Adaptive routing can avoid unnecessary questions, but there is no universal time-saving percentage or completion-time range. The walkthrough uses an illustrative 30-minute limit and a 21-minute completed session, not a typical-duration benchmark.
Validation and reliability are specific to the assessment, version and reference population. Request the technical documentation for your selected instrument, including the applicable reliability measure, norm sample and validity evidence. Illustrative report figures are not validation evidence.
