NPT (Normalized Penalty Total)
Definition
A metric used in MQM scoring that normalizes total error penalties per 1,000 words of source text. This allows fair comparison across documents of different lengths. Formula: NPT = (Total Penalties ÷ Total Words) × 1,000. Lower NPT = higher quality.
How this shows up in leapCAT
leapCAT's MQM score is calculated as 100 - NPT. Pass threshold is NPT < 5 (score ≥ 95). An early quality checkpoint requires NPT < 20 before proceeding to final review.
