What this page ranks
This page ranks 1,449 of the 1,794 assessed CRO agencies in United States — the ones carrying a published score — out of 2,092 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 1,794, so the strongest award available here is top 1%.
The 298 CRO agencies not yet assessed are listed on this page but not ranked.
A further 345 were assessed and no published evidence of their work was found, so no score is shown for them.
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.
