The concept of mentoring students or new employees to prepare them for advancement fundamentally begins with the direct supervisor. This is because a supervisor has a vested interest in the development and success of their team members. They possess a deep understanding of the organization’s goals and the skills required for advancement within the specific environment.

Supervisors typically have the authority to guide and influence the careers of their employees directly, making them ideally positioned to identify strengths, areas for improvement, and necessary growth opportunities. When a supervisor takes on a mentoring role, they can provide personalized feedback and support that aligns with both the employee's aspirations and the organization's needs.

Other figures, such as school counselors or potential employers, may offer guidance or advice, but it is through the direct supervision and mentorship that employees receive tailored support to prepare them for further responsibilities and career advancement. In this context, the supervisor is the primary source of mentorship, facilitating professional growth through ongoing communication, training, and evaluation.
