Glasgow Coma Scale (GCS)

The Glasgow Coma Scale rates three responses: eye opening, verbal response, and best motor response. Their sum, from 3 to 15, describes a patient’s level of consciousness and how it changes over time. Rate each response to score it, see what the total means after a head injury, and record the result with the free template.

Score the GCS as you answer.

Every item as published. The total and what it means update with each answer; nothing you choose leaves this page.

Check for factors interfering with communication, ability to respond and other injuries. Observe eye opening, content of speech and movements of right and left sides. Stimulate with sound, a spoken or shouted request, then with physical pressure on the finger tip, trapezius or supraorbital notch. Rate each component according to the highest response observed.

  1. 1.Eye opening

  2. 2.Verbal response

  3. 3.Best motor response

Use it for

  • Emergency department triage
  • Prehospital care
  • Neuro observations
  • ICU monitoring
  • Head injury assessment

What the score means. 3 to 15.

3 to 8: Severe

Coma, by the usual definition. Protect the airway, with intubation usually considered at 8 or less, and get an urgent CT head and neurosurgical input.

9 to 12: Moderate

CT head, neurosurgical advice, and admission for frequent neuro observations. Watch closely for any fall in the motor score.

13 to 15: Mild

Decide on CT with a head CT decision rule and the injury history. Repeat observations until the patient is back to 15.
  • Rate each component by the best response seen, and add the three for a total from 3 to 15. Write it with the components: E3 V4 M6 = 13.
  • The components say more than the total. A total of 8 can be E2 V2 M4 or E1 V1 M6, two very different patients.
  • When a component can’t be tested, such as the verbal response with a breathing tube or eyes closed by swelling, record NT for it, not 1. The Glasgow guidance is to give no total then, since a low total makes the patient look sicker than they are.
  • Many units write the intubated verbal response as VT, as in E2 VT M5. Some also write a total with a T, such as 8T, counting the verbal as 1; if yours does, keep the components beside it.
  • The bands are the usual classification of head injury severity: 13 to 15 mild, 9 to 12 moderate, 3 to 8 severe. Some classifications put 13 with moderate injury, since more of these patients have injuries on CT.
  • A fall matters more than any single score. Head injury guidance quoted on the official site asks for urgent review after a 1-point drop that lasts 30 minutes, a drop of 3 in eye or verbal, or a drop of 2 in motor.
  • The GCS-Pupils score subtracts 1 when one pupil doesn’t react to light and 2 when neither does, for a range of 1 to 15.
  • Children over 5 are rated on this scale. Younger children need a pediatric version, which fits the verbal and motor responses to their age.

How to give it, score it, and read it.

Checking first

Before rating, look for anything that stops a response from showing: a breathing tube, sedation, paralysis, swelling around the eyes, deafness, language, or a spinal cord injury.

  • Note each factor and the component it affects
  • Pause sedation for the assessment where that’s safe
  • Use the patient’s language, or an interpreter, before calling the verbal response confused

Avoid: Rating a response that couldn’t be tested as 1. Record NT and the reason.

Observing and stimulating

Watch first for what the patient does unprompted, then speak, then apply pressure only if there’s still no response.

  • Speak in a normal voice, then shout, before using any physical stimulus
  • Use finger tip pressure for eye opening and flexion, then a trapezius pinch or supraorbital pressure to look for localising
  • Build the pressure up gradually, and stop when the patient responds

Avoid: A sternal rub. It bruises, and the response is hard to read; the official guidance strongly discourages it.

Rating each component

Rate each component by the best response seen, against the defined criteria.

  • Eyes: open before any stimulus is spontaneous, after a spoken or shouted request is to sound, after finger tip pressure is to pressure
  • Verbal: orientated means the patient gives their name, place, and date correctly; confused means talking coherently but not orientated; words are single words that make sense; sounds are moans or groans
  • Motor: obeying means following a two-part request; localising means bringing a hand above the collarbone toward a stimulus on the head or neck
  • Score the better arm for the motor response, and record any difference between sides

Avoid: Taking a grasp reflex as obeying commands. Ask the patient to let go as well as squeeze, or to stick out their tongue.

Telling flexion apart

Normal flexion is a quick bend at the elbow, the arm moving away from the body. Abnormal flexion is slow and stereotyped.

  • Abnormal flexion: the arm crosses the chest, the forearm turns, the thumb clenches, and the leg often straightens
  • Extension: the arm straightens at the elbow
  • Ask a colleague to look too when you’re unsure, and record what you both saw

Recording the trend

Write all three components with the total, and chart each assessment so a change is easy to see.

  • Record E3 V4 M6 = 13, with the words for each response
  • Record pupil size and reaction alongside the GCS
  • Repeat often at first: every 30 minutes after an acute head injury until the patient is back to 15
  • Escalate any fall in the motor score at once

Avoid: Handing over the total alone. The next clinician can’t tell which response has changed.

Not testable and intubation

When a component can’t be tested, record NT and the reason, and follow the components that can be tested.

  • Write the intubated verbal response as VT or NT
  • Give the components, such as E2 VT M5, instead of a total
  • Track eye opening and motor response over time; the motor response carries the most weight in severe injury

Avoid: Counting NT as 1. It lowers the total, makes the patient look sicker, and confuses the team.

Two recorded results. Every part, filled in.

Each one follows the recording template. Use them to judge how much to write.

GCS result: head injury after a fall, score falling

Emergency department, 78-year-old woman on apixaban, fall at home about 2 hours earlier

Components

Eye opening E3: eyes closed until spoken to, then open. Verbal V4: talks in full sentences and knows her name, but thinks it’s morning and that she’s at home. Best motor M6: squeezes and lets go on request with both hands. Stimulus: spoken request; no pressure needed. NT: none; hearing aids in, English her first language.

Score

E3 V4 M6 = 13, mild head injury. Pupils 3 mm, equal and reactive. No weakness in any limb.

Trend

Paramedics recorded E4 V5 M6 = 15 at the scene and E4 V4 M6 = 14 on arrival at 09:10. 09:40: E3 V4 M6 = 13. 10:10: 13, unchanged. Down 2 points since the scene, and the drop has lasted over 30 minutes.

Actions

Emergency physician told at 09:42 and reviewed at once. Urgent CT head: 7 mm acute right subdural hematoma, no midline shift. Apixaban held and reversed per protocol; neurosurgery consulted and advised admission. GCS and pupils every 30 minutes; repeat CT for any further fall, especially in the motor response.

Common mistakes, and how to avoid them.

Reporting only the total

A total of 8 can be E2 V2 M4 or E1 V1 M6. Write the three components every time.

Scoring 1 for not testable

A patient with a breathing tube hasn’t got “no verbal response”. Record VT or NT, and give no total.

Missing a falling motor score

A drop in the motor response matters most. Compare each assessment with the last one, and escalate a drop at once.

Using a sternal rub

It bruises and gives responses that are hard to read. Use finger tip pressure, then the trapezius or the supraorbital notch.

Calling a grasp reflex obeying

A hand that grips can be a reflex. Ask for a second step, such as letting go, before scoring 6.

Frequently asked questions.

How do you calculate the Glasgow Coma Scale?

Rate eye opening from 1 to 4, verbal response from 1 to 5, and best motor response from 1 to 6, each by the best response seen. Add the three for a total from 3 to 15, and write it with the components, such as E3 V4 M6 = 13.

What does a GCS score mean?

A GCS of 15 is fully alert and orientated; 3 is no response at all. After a head injury, 13 to 15 is mild, 9 to 12 moderate, and 3 to 8 severe. A total of 8 or less is the usual definition of coma, and the point where airway protection is considered.

How do you score the GCS in an intubated patient?

Rate eye opening and motor response as usual, and record the verbal response as not testable: VT or NT. The Glasgow guidance is to give no total then, since counting the verbal as 1 makes the patient look sicker. Some units write a total with a T, such as 8T; if yours does, keep the components beside it.

Why does the GCS say “to pressure” instead of “to pain”?

The wording was updated to describe the stimulus actually used. In the same update, “inappropriate words” and “incomprehensible sounds” became “words” and “sounds”. The scores didn’t change, and the six-point motor scale, with normal and abnormal flexion, is now recommended for all purposes.

What is the GCS-P score?

The GCS-Pupils score combines the GCS total with pupil reaction. Subtract 1 when one pupil doesn’t react to light, 2 when neither does, and nothing when both react. It runs from 1 to 15 and adds information about outcome, mostly in severe injury.

Is there a pediatric Glasgow Coma Scale?

Yes. Children over 5 are rated on the adult scale. Younger children can’t be orientated or follow commands, so pediatric versions fit the verbal and motor responses to what a child can do at that age. On the Adelaide version described on the official site, a normal total is lower in infants. Name the version you used in the record.

Show all questions
How is the GCS different from AVPU and the FOUR score?

AVPU, for alert, voice, pain, unresponsive, is a quicker check used in triage; responding only to pain roughly matches a GCS of about 8. The FOUR score rates eyes, motor response, brainstem reflexes, and breathing from 0 to 16, and needs no verbal score, so it suits intubated patients.

Who can do a GCS assessment?

Any trained clinician. Nurses, doctors, and paramedics all use it, and studies show nurses and doctors rate it equally well. Training in the structured approach on the official site makes ratings more consistent.

Is the Glasgow Coma Scale free to use?

Yes. It’s free for clinical care and research with no licence needed, with the University of Glasgow’s copyright acknowledged. The official assessment aid is on the Glasgow Coma Scale site, and the recording template on this page is free to copy or download too.
