What percentage sustainment is used as the passing threshold for Marines?

• A. 80%
• B. 70%
• C. 95%
• D. 90%

Answer: (D)

Sustainment threshold is about keeping up the required level of performance across repetitions and under fatigue, not just hitting a perfect score once. Reaching a passing level of 90% means you must correctly perform at least nine out of ten required actions or moments under the test conditions, demonstrating reliable technique even as time and effort wear on you. This level strikes a balance between rigor and practicality: it ensures Marines can maintain proficiency in real-world scenarios where conditions aren’t perfect, without demanding flawless execution every single time. A lower threshold would allow more lapses to go unchecked, while a higher one would be unrealistic in field or training environments.
