How should trait grades be determined?

How should FITREP and Eval trait grades be determined?

Superstar Performance –5.0. Could be promoted two pay grades, and still be a standout in this trait.

Advanced Performance –4.0. Far more than promotion-ready in this trait right now.

Dependable, “Fully-Qualified,” Journeyman Performance –3.0. Can handle this aspect of the next higher pay grade.

Useful, Promising Performance –2.0. Needs development in this trait, but is promotable if overall performance warrants it (i.e., sufficient progress in this trait and no more than one other 2.0 trait). Exception: 2.0 trait grade cannot be assigned in Command or Organizational Climate/Equal Opportunity on reports in pay grades E1-E6 and W2-O6 and maintaina promotion recommendation of “Promotable” or higher. For pay grades E7-E9, a 2.0 trait grade cannot be assigned in Character and maintain a promotion recommendation of “Promotable” or higher.

Disappointing Performance –1.0. Until deficiencies are remedied in this trait, should not be promoted,regardless of performance in other traits.
