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 candidates answered 15 questions and another answered 14.
It is important to not place too much emphasis on question-related data to compare candidates:
For example, two candidates who each get 10 out of 15 questions correct may have received different questions at different difficulty levels.
The "T-score" is what is indicative of the candidate’s ability. This score grades the candidate compared to a larger group of candidates who took the same test and have similar education/experience. This is the best indicator for a candidate's performance.
