Final answer:
True, selection tests are crucial but should complement other selection tools like interviews and background checks to provide a comprehensive evaluation of a candidate's qualifications and suitability for a role.
Step-by-step explanation:
Selection tests should indeed be used as supplements to other tools like interviews and background checks. The use of personality tests, IQ tests, integrity tests, and physical tests such as drug tests or fitness tests are means of evaluating a candidate's knowledge, skills, and abilities (KSAs) to determine suitability for a position. However, screening tools are only part of the candidate analysis and testing process. Interviews can reveal dynamic information about candidates, including social factors and body language that tests cannot. Background checks provide additional context to a candidate's history and character.
Hiring decisions can be influenced by a variety of factors that are not necessarily related to job performance, such as the interviewee's similarity to the interviewer or physical attractiveness. Therefore, it is important to use a holistic approach in the candidate selection process, incorporating various methods to form a more complete picture of each applicant. Cutoff scores may be employed to determine eligibility for progression in the selection process, but they must be set carefully to ensure they do not exclude potentially suitable candidates.
