SCIM 2.0
368 providers in the API Evangelist catalog mention SCIM — the largest claim cohort of any standard in this programme. 77 of them publish an OpenAPI containing a SCIM path, and those are the denominator.
How it was measured
Two gradings per operation. `normative_force` is what RFC 7644 says, quoted. `tier` is what the industry declares, measured the same way as every other profile here. The gap between them is the point.
The core tier
What a provider has to implement before a compatibility claim means anything. Every placement is measured, and the evidence for each sits in the tier profile.

Adopters
| Evidence | Count | What it means |
|---|---|---|
| declared | 51 | Publishes a machine-readable spec declaring them. |
| prose | 269 | Says so, and publishes nothing a reader can check. |
Every entry in the registry carries the URL it was read from and the date it was read. A claim is never promoted to a verdict.
Providers that reach a tier
32 of the 320 recorded adopters demonstrably reach the core tier or better. The 24 below link to their catalog pages; the registry and matrix carry the rest.
