All of Workable's native cognitive ability assessments are "adaptive".
This means that when a candidate starts an assessment, they will be presented with questions and based on their responses, the following questions will either be more or less difficult. The difficulty of the test adapts to the ability of the candidate.
The adaptive methodology allows us to detect the candidate’s ability with accuracy, as well as minimize the time the candidate has to spend taking the test.
Because of this adaptive approach, not all candidates will be presented with the same number of questions and may not see the exact same questions. When viewing results you may find that one candidate answered 15 questions and another answered 14.
Keep in mind, two candidates who each get 10 out of 15 questions correct may have received different questions at different difficulty levels. A candidate who gets difficult questions correct would ultimately score higher than someone who gets easy questions. It is important to not place too much emphasis on question-related data to compare candidates.
Instead, a "T-score" is used to present results, which measures the candidate’s competency for the assessment type. The T-score is the best way to pinpoint a candidate's ability. Candidates are compared against the average performance of all candidates globally that have taken the same type of test. A score above 50 indicates above average performance.
