Sport Concussion Assessment Tool (SCAT-3) or (SCAT-5)
The instrument is freely available here: Sport Concussion Assessment Tool
Core: Sport-Related Concussion (SRC) Acute (time of injury until 72 hours) and Sport-Related Concussion (SRC) Subacute (after 72 hours to 3 months)
Supplemental-Highly Recommended: Sport-Related Concussion (SRC) Persistent/Chronic (3 months and greater post concussion) for post concussive TBI related symptoms.

|Short Description of Instrument||
The SCAT-3 (or SCAT-5) is a standardized tool for evaluating injured athletes for concussion and can be used in athletes aged 13 years and older. The SCAT-3 (or SCAT-5) was developed through concensus at the 2012 (and 2016 for SCAT-5) Concussion in Sport Group meeting. It consists of the Glasgow Coma Scale, Maddocks' questions, a Symptom Evaluation, the Standardized Assessment of Concussion (a cognitive assessment of orientation, immediate memory, concentration, and delayed recall), neck examination (for SCAT-3), neurological screening (for SCAT-5), a balance examination modified BESS, and Coordination Examination (for SCAT-3). The SCAT-3 (or SCAT-5) can be used to inform the medical provider's clinical examination.
Advantages: Packages the most commonly recommended and implemented concussion assessments. Designed as a assessment of multiple domains associated with concussion, including assessments of symptoms (Post-concussion Symptom Inventory [PCSI]), Glasgow Coma Scale (GCS), modified Balance Error Scoring System (mBESS: balance test), Standardized Assessment of Concussion (SAC: brief cognitive test), and Maddocks questions (orientation to place/time). Post-injury scores can be compared to baseline levels, but not required
Limitations: Not sensitive to post-concussion decrements beyond 48–72 hours post-injury. Should not be administered to those under the age of 13, but a child version of the SCAT-3 is available. SCAT-5 is not available. Not designed for sub-acute time period or to monitor recovery or determined return to play/sport. Lacks established clincial cut-offs in the absence of baseline scores. Subtests – BESS, SAC have limited utility after the first 72 hrs- more appropriate as an acute measurement.
Subpopulation: Adolescent to Adult/Pediatric version also available and should be included.
Limitations: Age Range: 13+
The SCAT-3 and 5 has no total score, but each section has the following ranges: Glasgow Coma Scale (3 to 15), Maddocks' questions (0 to 5), a Symptom Evaluation (0 to 22 for total symptoms; 0 to 132 for symptom severity), the Standardized Assessment of Concussion (0 to 30; modified version 0 to 50), neck examination (unscored) (for SCAT-3), modified BESS (0 to 30; modified version 0 to 50), and Coordination Examination (0 to 1) (for SCAT-3).
The SCAT-3 (or SCAT-5) is administered in interview-format to an athlete with suspicion of sustaining a concussion. the SCAT-3 (or SCAT-5) is designed for?use?and interpretation by?appropriately trained medical?professionals.
Preseason baseline testing can be performed to allow comparison with post-injury scores, but is not required. There are no overall scoring criteria, but sensitivity and specificity scores are available for the components. The SCAT-3 (or SCAT-5) loses sensitivity to post-injury changes within 48 to 72 hours.
