What is my Compliance Health Score, and how is it calculated?

It's the ring chart at the top of your Dashboard — a single percentage meant to answer "how compliant is my library right now," rolled up from a dynamic, weighted pool of metrics shown underneath it (the dashboard code supports up to six possible metrics; how many actually apply depends on your account):

• 1 Overall Compliance Health Score
• 2 One of the metrics it's built from

• SDS Currency — how many of your SDSs are on the latest supplier revision
• Disposal Classification — how many SDSs in your library have a disposal category assigned
• SDS Quality — how many SDSs pass the automated quality check
• PPE Review Progress — how many auto-suggested PPE icons have been reviewed and approved

More on each of these: Disposal Classification, SDS Quality, and PPE Suggestions Review.

This isn't a simple average of four fixed, equally-weighted sub-scores — it's a weighted, pooled ratio across however many of the (up to six) supported metrics apply to your account, so the exact set feeding your score, and the calculation itself, can differ from another account's.
