Pick the eye, verbal and motor responses to get the Glasgow Coma Scale total and the standard notation. A study aid for learning how the scale is built.
Educational use only - not for patient careThis uses the adult verbal scale. Scoring for young children differs.
Choose a response in each row.
The Glasgow Coma Scale is a core assessment idea in emergency medical services study. Encodr turns it into spaced-repetition practice so it holds until exam day.
Get started freeThis calculator is a learning aid. It is not a medical device, it does not assess any real patient, and it must not be used to make or support clinical or triage decisions. Follow your training, your protocols and your medical director for anything involving a patient.
The scale adds three components: eye opening (1 to 4), verbal response (1 to 5) and motor response (1 to 6). The lowest possible total is 3 and the highest is 15. It is usually written with the parts shown, for example GCS 13 (E4 V4 M5), because the pattern carries more information than the total alone. The severity bands shown by this tool (13 to 15, 9 to 12, 3 to 8) are the commonly taught groupings and are for study only.
The EMT certification exam is built on task areas such as primary assessment, which includes assessing the patient's level of consciousness. See the guide to how the NREMT cognitive exam works and the NREMT EMT course page for free flashcards on the five content areas.
How adaptive testing decides pass or fail on the NREMT EMT exam, why the length varies from 70 to 120 items, and what the five content areas weigh.
A study plan built on the NREMT EMT test plan weights: where to spend your time, how to handle adaptive testing, and how to use spaced repetition.
How the EMT and paramedic certification levels differ in scope, what the EMT exam is designed to measure, and how to decide which to pursue.
