SHORTS: How often should bias audits run during project lifecycles

Bias audits in M&E project lifecycles should follow a layered, risk-based cadence aligned with standard phases like baseline, monitoring, mid-term review, and endline evaluation to catch drift early without overburdening teams.verifywise+1

Recommended Frequency by Phase

Tailor to project duration (e.g., 1-5 years) and AI risk level (high-risk like beneficiary targeting needs tighter intervals). Use continuous KPI monitoring for daily alerts, reserving full audits for checkpoints.

• Pre-Deployment (Baseline): Full audit once—data representativeness, model fairness (DIR/EOD checks)—before go-live.[nature]​

• Active Monitoring: Lightweight scans monthly (PSI/KS drift, GERP); automate 90% via dashboards.[arxiv]​

• Milestones (Mid-Term/Quarterly): Comprehensive audits every 3-6 months or post-retrain, including stakeholder vignettes.[verifywise]​

• Endline/Post-Project: Final deep-dive audit with longitudinal amplification analysis.[ceur-ws]​

• Ad-Hoc Triggers: Immediate for KPI breaches (>0.1 EOD), major data shifts, or incidents (e.g., override spikes).[relyance]​

Cadence Table for Typical 3-Year M&E Project

High-risk projects (e.g., health interventions) shift to bi-monthly full audits; low-risk (internal reporting) annually. Document rationale per EU AI Act for compliance, iterating based on false positive rates.lexpert+1
