Which of the following is NOT a task proficiency rating code described?

• A. N = novice
• B. T = trained
• C. P = needs practice
• D. U = untrained

Answer: (B)

Proficiency ratings are meant to quickly indicate how well someone can perform a task right now, based on observed ability. In the described rating system, the categories that appear are states like being a novice, needing practice, or being untrained—these describe current capability and readiness to perform. The label for someone who is already “trained” isn’t part of that set, because having completed training isn’t the same as presenting a current performance level; it’s more about prior preparation rather than how well the task is being executed at the moment. So, a code that equates to “trained” isn’t described in that rating scheme, which is why it’s the one that doesn’t fit.

The other codes align with the described system: novice reflects limited experience, needs practice signals that improvement is required, and untrained indicates no proficiency yet.
