Explosive detector dogs are required to maintain what accuracy rate?

• A. 90%
• B. 92%
• C. 93%
• D. 95%

Answer: (D)

The required accuracy rate is 95%. In practice, this means a dog must correctly identify the presence of explosives and correctly ignore non-explosive items in about 95% of testing trials. This high standard reflects the safety-critical nature of explosive detection, where missing an explosive (a false negative) or overreacting to harmless items (a false positive) can have serious consequences. Accuracy is typically measured as the proportion of correct responses (both true positives and true negatives) out of all trials. A 95% target provides strong reliability across different handlers and environments, whereas lower thresholds would reduce confidence in real-world deployments.
