In two out of five quizzes on Coursebox, every single learner passed on their first attempt.

I looked at 131,527 graded quiz attempts from learners on Coursebox courses between August and October 2026, following each learner through each quiz. **Learners pass 79% of quizzes first time, 41% of quizzes are passed first time by everyone, and almost every learner who fails tries again and passes.**

## How often do learners pass a quiz on the first attempt?

Learners pass 79% of quizzes on their first attempt, according to Coursebox's analysis of 65,803 learner quiz results (August to October 2026). Across whole courses, the median course has a pass rate of 76% of all graded attempts, with the middle half of courses between 62% and 91%.

| Category | Value |
| --- | --- |
| 25th percentile | 62% |
| Median | 76% |
| 75th percentile | 91% |

Base: 131,527 graded attempts in 242 courses with 10 or more graded learners, Aug to Oct 2026

That range is wide. Two courses on the same platform can sit 30 points apart, which usually says more about the questions than about the learners.

## How many quizzes does everyone pass?

41% of quizzes are passed by every learner on the first attempt, and 54% by at least 90% of learners. At the other end, 15% of quizzes are failed by more than half of learners the first time.

_Quizzes by first-attempt pass rate_

| Category | Value |
| --- | --- |
| Under 50% | 15% |
| 50 to 70% | 11.5% |
| 70 to 90% | 19.4% |
| 90 to 95% | 8.8% |
| 95% or more | 45.1% |

Base: 1,990 quizzes with 10 or more learners, in 242 courses, Aug to Oct 2026

A quiz that everyone passes can still do a job, for example confirming that a learner read a compulsory policy. It cannot separate learners who understood the material from those who found the question easy, though.

## What happens when a learner fails a quiz?

Almost every learner who fails a quiz tries again, and almost all of them then pass. 99% of learners who failed a first attempt retried, 99% of those passed, and 99.7% of learner-quiz pairs ended in a pass. 80% of learners needed one attempt, 13% two and 8% three or more.

_Attempts needed to pass a quiz_

| Category | Value |
| --- | --- |
| One attempt | 79.5% |
| Two attempts | 12.5% |
| Three or more | 8% |

Base: 65,803 learner-quiz pairs, Aug to Oct 2026

A retake that almost always ends in a pass works as a gate: learners keep going until they clear it. That is useful for completion, but a second attempt at the same questions mostly tests memory of the first.

## What scores do learners get on their first attempt?

65% of first attempts score 100%. Another 14% score between 80% and 99%, and 8% score under 40%.

_First-attempt quiz scores_

| Category | Value |
| --- | --- |
| Under 40% | 7.7% |
| 40 to 59% | 4% |
| 60 to 79% | 9.8% |
| 80 to 99% | 13.5% |
| 100% | 65% |

Base: 65,803 first attempts, Aug to Oct 2026

When two thirds of learners get every question right, the quiz may be confirming what they already knew. Questions that ask learners to apply an idea to a situation spread scores out and show who needs more help.

## How do you set the right quiz difficulty?

Aim for a first-attempt pass rate between 70% and 90% on quizzes meant to check understanding, and review any question almost everyone gets right or most people get wrong. This is the prompt I use to make AI quiz questions test application rather than recall:

**Prompt: make quiz questions test application**

Paste into the AI editor on a quiz that almost every learner passes.

```
Rewrite this quiz for [AUDIENCE] so it tests whether they can apply [TOPIC], not whether they remember definitions.

- Turn each question into a short workplace scenario of 2 to 3 sentences.
- Make every wrong option a mistake a real [AUDIENCE] would plausibly make.
- Keep [NUMBER] questions and one correct answer each.
- Add a one-line explanation for the correct answer.
- Base every scenario on [SOURCE].
```

Replace these:
- `[AUDIENCE]`: Who takes the quiz (for example, new warehouse staff)
- `[TOPIC]`: What the module teaches (for example, safe lifting)
- `[NUMBER]`: Number of questions (for example, 5)
- `[SOURCE]`: The document the scenarios must follow (for example, manual handling procedure)

Check before you use it:
- Each question describes a situation, not a definition
- Wrong options are realistic mistakes
- Answers match your source

## How I measured this

The data is anonymised and aggregated. No names, email addresses or company details were used, no quiz content is published, and any group smaller than 30 is left out. It covers 131,527 graded quiz attempts on Coursebox between 1 August and 31 October 2026. Course pass rates use the 242 courses with 10 or more graded learners. First attempts, retakes and scores follow 65,803 learner-quiz pairs from 7,397 learners in those courses, and quiz-level figures use the 1,990 quizzes with 10 or more learners. Course creators and admins, bots, staff and test accounts are removed. The full methodology is in the report.
