Which statements are prohibited in evaluations?

The choice indicating that "prohibited promotion statements" are not allowed in evaluations is correct because evaluations must remain objective and based on measurable performance indicators rather than subjective promotions or personal observations. Prohibited promotion statements may include language that implies favoritism or unwarranted endorsements that are not substantiated by the actual work performance of the individual being evaluated. Evaluations should focus on factual achievements, specific skills, and contributions that align with established criteria rather than veering into promotional rhetoric that may compromise the integrity of the assessment process.

In contrast, the other options such as positive promotion statements and comments on unit achievements are generally acceptable as they can highlight the positive aspects of a unit's work or an individual’s contribution. Comments based on personal opinions may not be constructive in evaluations as they could introduce bias, but they don't necessarily fall under the outright prohibitions unless they negatively affect objectivity or clarity.
