Can You Fail a Baseline? What Agencies Should Actually Do with Invalid Tests

Yes, you can "fail" a baseline in the sense that the attempt is flagged as invalid. That is a normal part of concussion program quality control. The mistake agencies make is treating invalidity as either automatic misconduct or something to ignore. It is neither. It is a signal that the data quality is not good enough for safe post-injury comparison.

Validity indicators exist because baseline testing can be influenced by many variables: poor sleep, noisy rooms, confusion about instructions, effort fluctuation, or intentional underperformance. Research has shown that embedded invalidity checks can miss some intentional sandbagging and can also flag non-intentional poor-quality attempts. That is exactly why policy matters.

What invalid baseline usually means

• Testing conditions were poor (noise, interruptions, rushed timeline)
• Officer was sleep-deprived, ill, or symptomatic for unrelated reasons
• Instructions were misunderstood or not followed consistently
• Effort or engagement was insufficient for reliable data capture
• In some cases, potential intentional underperformance occurred

Good agencies assume process failure first, intent second. If baseline policy is punitive, officers are less likely to report symptoms later or engage honestly during retest. If policy is structured and fair, data quality improves and trust stays intact.

A better invalid-test protocol

1. Flag invalid baseline automatically through platform criteria
2. Re-test under controlled conditions (quiet room, clear instructions)
3. Document sleep, medications, and stress context on retest day
4. If repeated invalidity persists, route to clinician or neuropsych review
5. Do not use invalid baseline for return-to-duty comparison decisions

This approach protects both officers and agencies. It reduces false confidence in bad data and creates an auditable pathway for quality assurance. Most importantly, it reframes "failed baseline" from blame language to patient-safety language.

Communicating this to command and unions

Use clear wording: invalid does not equal unfit for duty; invalid means retest required for reliable baseline creation. When this distinction is explicit in SOP and briefing materials, resistance drops. Officers understand that the goal is better care after injury, not administrative punishment before injury.

For supporting education, share baseline testing fundamentals and retest and re-baseline cadence. Then connect policy urgency with law-enforcement underdiagnosis trends.
