Which statement is true about Task Knowledge Levels notation?

• A. Levels A to D.
• B. Levels a to d (lowercase).
• C. Levels 1 to 4.
• D. Levels I to IV.

Answer: (B)

Task Knowledge Levels are expressed with lowercase letters a through d to indicate increasing depth of knowledge required to perform a task. Using the lowercase sequence provides a clear, ordinal progression without mixing with other rating systems that might use uppercase letters, numbers, or Roman numerals. This distinction helps training materials map exactly what knowledge is needed for each task and keeps the notation unambiguous across documentation and assessments. The other formats—uppercase A–D, numbers 1–4, or Roman numerals I–IV—could be confused with different scales or categories, so they aren’t used for Task Knowledge Levels.
