Top block limit for NCOers?

• A. 60%
• B. 24%
• C. 49%
• D. 75%

Answer: (B)

The idea being tested is how many NCOs can be placed in the top performance tier in a given review or promotion context. This top block is kept selective to maintain meaningful distinction among performers, prevent inflation of top ratings, and ensure that boards have enough room to recognize truly standout NCOs without overloading the top category.

The best choice sets that cap at about a quarter of the NCO population. In practice, if you have 100 NCOs, only roughly 25 should appear in the top block. This keeps the top tier genuinely reserved for the highest performers and preserves the integrity of the rating or selection process. The other options would allow a much larger share to be labeled as top performers, which would dilute the significance of being in that block and undermine the purpose of having a distinct top tier.
