Quality Metrics

How We Measure Dataset Quality

Every dataset in our catalog passes the same quality framework before shipping. Here are the live metrics from our current production pipeline.

DATALENT data quality dashboard showing QA pass rate 99%, annotation accuracy 97%, compliance rate 100%, average delivery 48 hours, and an 8-week upward trend in datasets processed
Live production pipeline metrics — updated weekly
Our Quality Bar

99% QA Pass Rate. No Exceptions.

Every dataset batch goes through automated QA followed by expert human review. Tasks that fall below our threshold go back for re-annotation. The 1% that fails gets regenerated — not shipped with a caveat.

Inter-annotator agreement is tracked on every project using Cohen's kappa. Our minimum acceptable kappa score varies by domain, but is never below 0.80 — and averages 0.94 across our medical datasets.
