Which concept is the extent to which a hiring or selection tool is directly connected to job duties?

• A. Polygraph
• B. probationary period
• C. job relatedness
• D. selection process

Answer: (C)

Understanding how directly a hiring tool measures what matters for the job is essential. The best term here is job relatedness: it is the degree to which the instrument used in selection is tied to the essential duties, tasks, and requirements of the role. When a tool is job-related, it helps predict how well a candidate will perform on real job tasks and supports fair, legally defensible hiring by focusing on what the job actually requires.

Why this fits best: it captures the core idea that a tool should measure something that matters for performing the job, not just any irrelevant trait. For example, a test or structured interview that directly assesses required policing tasks or decision-making under stress is job-related.

Why the other options don’t fit as the core concept: a polygraph is a testing method with questionable relevance and validity to job performance and duties; a probationary period is simply a trial hiring phase, not a selection instrument tied to duties; the selection process describes the overall hiring method rather than the specific linkage between a tool and job duties.
