What document typically includes a summary of job duties and the expectations for a specific role?

The job description is the correct answer because it serves as a formal document that outlines the specific duties, responsibilities, and expectations associated with a role within an organization. It provides critical information for potential candidates, helping them understand what is required for the position. This document typically details the primary functions of the job, necessary qualifications, and any skills or competencies required.

In contrast, a company handbook is a broader document that usually includes information about company policies, procedures, and culture, rather than specific job roles. A training manual is designed to instruct employees on how to perform their jobs and may include operational procedures, but it does not summarize job duties per se. A performance report evaluates an employee's work and achievements over a specific period, focusing on their performance rather than defining their job responsibilities and expectations. Therefore, the job description specifically encapsulates the essence of a position, making it the most relevant document for this question.
