NIST SP 800-63-4 is the revision of the United States federal digital identity guidelines, which define assurance levels for identity proofing, authentication, and federation. It treats those three dimensions as independently selectable, so a service can set the strength of each control to match the risk of a given transaction instead of using one combined level.
