What this page ranks
This page ranks 1,000 of the 1,797 assessed CRO agencies in United States — the ones carrying a published score — out of 2,095 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, CRO in United States. 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 1,797, so the strongest award available here is top 1%.
The 1,095 CRO agencies not yet assessed are listed on this page but not ranked.
Paid placement
The Partner agencies in the labelled block at the top of this page pay for that placement and carry a direct link to their own website.
Placement is paid; it does not affect the ranking, cohort membership, or any agency's score. Ranking position, cohort membership and the score itself are not for sale.
