Which performance mark on the E7 through E9 evaluation specifically requires comments for justification?

The performance mark of 1.0 on the E7 through E9 evaluation specifically requires comments for justification because it indicates that an individual is significantly below the expectations for their rank and responsibilities. This low score reflects serious deficiencies in performance, and the requirement for comments ensures that the evaluator provides a clear, comprehensive understanding of the reasons behind such a poor evaluation.

By necessitating justification for a 1.0 mark, the evaluation process aims to maintain fairness and clarity in performance assessments, ensuring that the individual receiving the mark is fully aware of their shortcomings and can address the issues moving forward. The comments also serve as a formal record that can be referenced in future evaluations or for other administrative actions.

In contrast, the other performance marks typically do not have such stringent requirements for justification, particularly if they reflect acceptable or satisfactory performance levels. This is why only the 1.0 rating, signaling a critical need for improvement, requires explicit comments to explain the underlying reasons.
