Nancy Evans has accepted a position as third-grade grade-level chair and will receive a salary supplement for her role. This situation exemplifies which of the following concepts?

The situation described with Nancy Evans exemplifies a pay-for-performance system because she is receiving a salary supplement specifically for taking on the additional responsibilities associated with her role as grade-level chair. This type of approach incentivizes educators to take on leadership roles or additional duties by providing financial rewards linked to their performance or contributions to the school.

In a pay-for-performance system, compensation is aligned with certain achievements or responsibilities, illustrating a direct connection between the teacher's role and their compensation. This encourages educators to excel in their positions and take initiative in leadership, as they are recognized and rewarded for their increased contributions to the school's functioning.

While other concepts relate to teacher evaluation, professional development, or collective bargaining, they do not directly address the individual financial incentive structure that characterizes the role Nancy holds which provides her with a salary supplement.
