WHAT SETS CRITERIA APART
Where Criteria is purpose-built for hiring
For growing teams, Criteria pairs a modern experience with the scientific rigor, safeguards, and predictable costs needed to make better hiring decisions at scale.
Predictable costs as hiring volume grows
Criteria uses flat-fee package pricing, so costs remain predictable as candidate volume grows instead of increasing through per-candidate credits or escalating overage rates.
20+ years of validated hiring science
Assessments are built and validated by an in-house I/O psychology team, with 300+ validation studies and customer case studies tying the assessments to real outcomes.
60+ ATS integrations
Criteria connects to 60+ applicant tracking systems out of the box, the broadest dedicated ATS coverage in the market. Assessments and interviews slot into the workflows teams already run, no rip-and-replace required.
Built for the full talent lifecycle, from selection to development
Criteria is validated by in-house I/O psychologists, with adverse impact and validity evidence for the roles you hire. The same science behind defensible hiring decisions carries into post-hire development, all on one connected platform.
Candidate integrity and accessibility by design
Industry-leading candidate integrity safeguards help protect signal quality through structured anti-fraud and identity controls, without relying solely on restrictive test environments that can create accessibility friction.
Explainable, human-in-the-loop AI
Criteria uses transparent, bias-tested AI that's backed by ISO 42001:2023 certification, the first global standard for AI Management Systems, providing an auditable signal that our AI is fair and accountable.
