About this ranking

What this page ranks

This page ranks the 2 backend development agencies in Illinois that have been assessed on the Agency List Score, out of 33 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, Backend Development in Illinois. 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 2, so no award can be issued here.

The 31 backend development agencies not yet assessed are listed on this page but not ranked.
