Aptitude tests or ability tests are standardized assessments to determine the performance of the respondent on the given tasks. Often used during a recruitment process, these assessments must test the candidate on skills required for the given role. The tests usually include work-related tasks or example situations for the candidate to respond to.Instead of just measuring intelligence, these evaluations can determine how well-suited the candidate is to the tasks of the position. They are a great predictor of performance in the role, which is why ability tests are used so often during the hiring process; they can help recruiters to make better hiring decisions.
