Four design properties
- Coverage: items map to a declared skill taxonomy.
- Validity: answer keys reviewed by qualified people; label errors measurably affect rankings (Northcutt, Athalye, Mueller, arXiv:2103.14749).
- Freshness: items not exposed online, to limit training contamination.
- Documentation: a datasheet-style record of how items were made (Gebru et al., arXiv:1803.09010).
Private vs public benchmarks
Public benchmarks enable comparison but leak into training corpora over time. Private, held-out sets keep measurement value longer — which is why some owners license data for evaluation only, never training.
