About this ranking

What this page ranks

This page ranks 3 of the 4 assessed microsoft 365 administration agencies in California — the ones carrying a published score — out of 115 listed.

The score measures how well an agency documents its own work in public — named clients, quantified outcomes, and whether those outcomes are attributed to the agency rather than described as the client's own results. It does not measure client satisfaction, price, or availability.

Cohorts and awards

Agencies are compared within a cohort — here, Microsoft 365 Administration in California. A cohort must be large enough to express the band being awarded: at least 8 assessed agencies for a top 25% award, 20 for top 10%, 40 for top 5%, and 300 for top 1%. This one holds 4, so no award can be issued here.

The 111 microsoft 365 administration agencies not yet assessed are listed on this page but not ranked.

One more was assessed and no published evidence of its work was found, so no score is shown for it.
