Why must multiple versions of the examination be used?

Using multiple versions of an examination serves the critical function of preventing cheating among candidates. When the same test is administered to all candidates, it increases the likelihood that individuals may share answers or use other dishonest methods to gain an advantage. By having different versions of the test, each with varying questions or arrangements, the integrity of the examination process is upheld. This method ensures that each candidate is evaluated based on their individual knowledge and abilities, minimizing the potential for collusion and unfair practices during the testing process.

The other options do not capture the primary reason for employing multiple test versions. Variations in examination content and ensuring that applicants are tested on the same material relate more closely to the overall fairness and consistency of the exam rather than the direct issue of cheating prevention. Maximizing the number of applicants who pass is not a goal of using multiple test forms; rather, the focus is on maintaining integrity and fairness in the evaluation process.
