What is SCAT6? The Gold-Standard Concussion Assessment

SCAT6 introduces several evidence-based updates from the 2022 Amsterdam Consensus: a 10-word immediate memory list (vs 5 words in SCAT5) to address ceiling effects, dual-task gait assessment, a new cognitive composite score, timed concentration testing (months in reverse within 30 seconds), enhanced orientation questions, improved neurological examination with reading assessment, and clearer interpretation guidance. These changes improve detection sensitivity across cognitive and motor domains.

No. SCAT6 is designed exclusively for licensed healthcare professionals trained in concussion assessment. For coaches, parents, teachers, and other non-medical personnel, use the CRT6 (Concussion Recognition Tool 6) instead, which helps recognise when professional evaluation is needed. CRT6 is intended for immediate sideline use by anyone.

A complete SCAT6 assessment takes a minimum of 10–15 minutes when administered properly, and typically 15–20 minutes in practice. This includes the symptom evaluation, cognitive testing, neurological screen, and balance examination. Rushing the assessment can compromise accuracy. SCAT6 cannot be performed correctly in less than 10 minutes.

SCAT6 does not produce a simple pass/fail result. It provides domain-specific scores that require clinical interpretation. Any athlete with abnormal findings, worsening symptoms, or clinical concern should be removed from play, monitored, and managed according to established concussion protocols. The worse an athlete scores compared to their baseline, the more likely they are to have a concussion – but normal scores do not rule it out.

Use SCAT6 for acute assessment within 72 hours of suspected injury – this is when it has the highest sensitivity. After 72 hours, transition to SCOAT6 (Sport Concussion Office Assessment Tool 6) for ongoing office-based evaluation and recovery monitoring. SCOAT6 includes extended neurological examination, mental health integration (GAD-7, PHQ-2), and treatment planning components that SCAT6 does not cover. Try ScreenIT’s free digital SCOAT6.

Baseline testing is recommended but not required. Having pre-injury baseline data significantly improves interpretation by allowing comparison against the individual’s normal function rather than population norms alone. Without baseline, you can use normative data – World Rugby has published reference values from over 13,000 baseline assessments in elite players. However, individual variation is significant, and the SCAT6 does not define standardised acceptable scores.

No. SCAT6 is a clinical assessment tool that supports decision-making, not a diagnostic test. Concussion diagnosis requires clinical judgment integrating history, mechanism of injury, examination findings, and symptom presentation. A normal SCAT6 does not rule out concussion. The CISG explicitly states: “an athlete can score within normal limits on the SCAT6 and still have a concussion.”

SCAT6 produces scores across multiple domains: Symptom Count (0–22), Symptom Severity (0–132), Orientation (0–5), Immediate Memory (0–30 across 3 trials of 10 words), Concentration (0–5), Delayed Recall (0–10), mBESS balance errors (0–30), and timed tandem gait. These are combined into a Cognitive Composite Score (new in SCAT6). There is no single total score – each domain is interpreted individually and compared to baseline or normative data.

The official SCAT6 PDF was published in the British Journal of Sports Medicine (June 2023, Vol 57, Issue 11) and may be freely copied for clinical use. You can download the SCAT6 PDF here or access the original publication at BJSM. For a digital version with automated scoring, try ScreenIT’s CISG-approved digital SCAT6 for free.

The cognitive composite score is new in SCAT6. It combines orientation, immediate memory, concentration, and delayed recall into a single metric. This was introduced based on systematic reviews showing that a combined score improves consistency across repeated evaluations and reduces false positive outcomes compared to interpreting individual subtests alone.

Red flags are emergency signs that require immediate medical evaluation and may indicate a more serious injury than concussion. SCAT6 red flags include: neck pain or tenderness, double vision, weakness or tingling in arms or legs, severe or increasing headache, seizure or convulsion, loss of consciousness, deteriorating conscious state, vomiting, increasingly restless or agitated, GCS below 15, and suspected skull fracture. If any red flag is present, the athlete should be immediately transported to the nearest emergency department.

Yes. While the paper SCAT6 is freely available, digital reformatting requires written consent from BMJ and the CISG. ScreenIT has this official CISG authorisation and offers a free digital SCAT6 with automated scoring, guided step-by-step administration, built-in timers, instant PDF reports, and secure cloud storage. The digital format maintains item-for-item fidelity with the published version.

SCAT6 informs but does not determine return-to-play decisions. It is one component of a comprehensive concussion management approach. After acute assessment with SCAT6, athletes follow a graduated return-to-sport strategy with a minimum of 6 stages over at least one week. Medical clearance is required before returning to full-contact practice. Serial assessments (including transition to SCOAT6 after 72 hours) track recovery and guide progression through each stage.
