In order for saving to be graded as progressing, what recommendation must he have received on his current in-grade performance evaluation?

For a member to be graded as progressing, they must have received a recommendation that indicates they are meeting performance expectations during their in-grade evaluations. A recommendation of "no significant problems" highlights that the service member is maintaining adequate performance levels.

In this context, the correct choice indicates a recommendation constitutes a significant problem, which does not support a positive evaluation necessary for progression. The evaluation system is designed to flag when performance issues exist, thus affecting the individual's ability to advance within their rank.

The other selections do not align with the requirements for a progressive evaluation. "Unable to evaluate" indicates uncertainty in performance assessment and does not contribute positively to a progression grading. "Need improvement" suggests there are areas where the service member is lacking, which would not support advancement. Therefore, the criteria for progression must reflect adequate performance without significant issues.
