A Clinical Research Associate (CRA) is a clinical trial monitor who evaluates study conduct at investigative sites on behalf of a sponsor or contract research organization.
CRAs verify protocol adherence, confirm informed consent documentation, and perform source data verification to support data integrity. They identify compliance gaps, escalate issues, and confirm corrective actions are implemented. Monitoring activity supports sponsor oversight and inspection readiness. The CRA role is essential for consistent trial quality across multi-site studies.
