Clinical context: when SUS is used

30-item measure of stressful life events specific to college and university students. SUS is part of standard practice in this setting because it provides a structured, replicable assessment that can be tracked over time and compared across patients or visits.

Like all screening or assessment instruments, SUS is a structured aid — not a diagnostic test in isolation. Results should be interpreted alongside history, examination, and clinical context. Where a score crosses an actionable threshold, the next step is typically a more detailed clinical evaluation rather than a definitive diagnosis.

Answer all 10 items below to see your SUS score and interpretation.

Each item is scored on a 5-point scale (1–5). Your score updates live as you answer.

All scoring runs in your browser. No data is sent anywhere — close the tab and the answers are gone.

How SUS is scored

Count endorsed events weighted by severity. Total range 0-1000+. Higher scores = greater cumulative stress.

Scoring notes: Count endorsed events weighted by severity. Total range 0-1000+. Higher scores = greater cumulative stress.

How to score SUS: a step-by-step worked example

This is an illustrative walkthrough, not a real patient. Follow the same four steps with your own answers — or use the live calculator at the top of this page.

Step 1 — Score each item

Read each question and choose the response that best fits. Each response has a number next to it — that number is the item's score. The example below uses illustrative answers.

#ItemExample responseScore
1I think I would like to use this system frequentlyStrongly agree5
2I found the system unnecessarily complexStrongly disagree5
3I thought the system was easy to useStrongly agree5
4I think I would need the support of a technical person to use this systemStrongly disagree5
5I found the various functions in this system were well integratedStrongly agree5
6I thought there was too much inconsistency in this systemStrongly disagree5
7I would imagine that most people would learn to use this system very quicklyStrongly agree5
8I found the system very cumbersome to useStrongly disagree5
9I felt very confident using the systemStrongly agree5
10I needed to learn a lot of things before I could get going with this systemStrongly disagree5

Step 2 — Add up the scores

Add up all the item scores you noted in Step 1.

5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 = 50

Step 3 — Look up the band

Find the row in the interpretation table whose range contains your total:

Total = 50 falls between 0 and 150Low stress

Step 4 — What does this mean clinically?

Low stress. None

A score is one input alongside history and examination. SUS supports clinical judgment — it does not replace it.
