What must happen for negative counseling to impact a performance evaluation?

For negative counseling to impact a performance evaluation, the deficiency must be uncorrected. This means that simply counseling an individual about a problem is not enough; the individual must be given a reasonable opportunity to improve and correct the issue before it can be reflected in their performance evaluation. If the problem persists despite the counseling efforts, it demonstrates a lack of improvement and accountability, which justifies the inclusion of that negative aspect in their evaluation.

The focus here is on the importance of accountability and the expectation that individuals will take the feedback provided during counseling and make the necessary adjustments to their performance. This principle ensures a fair evaluation process, allowing Marines to understand the consequences of their actions and encouraging them to strive for improvement.
