AQ test scoring and what scores mean

Short answer
On the AQ test, each of 50 statements scores 1 point when answered in the autistic-trait direction, mildly or strongly, so totals run from 0 to 50. The authors chose 32 or more as a marker: 80% of autistic adults and 2% of controls in their 2001 study scored that high. A clinic study later suggested 26. Neither number diagnoses autism.
Most people meet AQ scoring after an online quiz hands them a number and a headline. The number is real arithmetic, but the headline often goes beyond what the research supports. Here is what the published sources actually say.
How the AQ is scored
Each statement has four answers: definitely agree, slightly agree, slightly disagree, definitely disagree. Some statements score a point if you agree, and the rest score a point if you disagree. Strength does not matter, so slightly agree and definitely agree count the same. Adding the points gives a total between 0 and 50. The five subscales of 10 statements each can also be totaled, from 0 to 10.
The 32 cut-off
That threshold came from a research comparison, not from a clinic. It describes a score range where autistic adults in that study were common and controls were rare. It was never meant as the line between autistic and not autistic for an individual.
The clinic threshold of 26
Lowering the threshold catches more autistic adults who score modestly, often because they have learned to manage or hide their traits. The trade-off is that more non-autistic people are flagged. This is why different sources give different cut-offs, and why your score near either line is ambiguous.
Average scores
| Group | Mean score |
|---|---|
| Autistic adults (58) | 35.8 |
| Randomly selected controls (174) | 16.4 |
Among controls, men scored slightly higher than women on average. No control woman scored 34 or above, while 4% of control men did. Later studies in different countries have reported their own averages, so treat these as a reference point rather than a norm table.
What does an AQ score of 32 or 35 mean?
A score of 32 is right at the published threshold: your answers resemble those of most autistic adults in the 2001 study. A score of 35 is close to the autistic group average of 35.8. Both are good reasons to consider an assessment if you are struggling or curious. Neither means you are certainly autistic. Many people with high scores are not autistic, and many autistic people score under 32.
Why the same person can score differently
AQ scores are fairly stable, but they are not fixed. A stressful period at work, a recent move, or a new understanding of your own patterns can shift several answers. People who start reading about autism sometimes notice traits they had never named, and their next score rises. Others realize they had been answering based on how they wished they were. Retaking the AQ many times rarely adds clarity. One honest attempt, plus notes about what each answer meant to you, is more useful.
AQ scores and anxiety, ADHD and masking
- Anxiety can push up social and attention-switching answers.
- ADHD shares attention and routine themes and can raise scores.
- Masking and long practice at social rules can pull scores down.
- Alexithymia can make self-report harder in either direction.
Subscale scores
Some online versions also report the five subscales: social skill, attention switching, attention to detail, communication and imagination, each scored 0 to 10. These can show where your answers cluster. For example, a person might score high on attention to detail and attention switching but low on social skill statements. Research has not established separate cut-offs for these areas, and an analysis of the AQ's structure found it does not behave as a single clean measure, so read subscale patterns as description rather than as findings.
Maximum score
The maximum AQ score is 50 and the minimum is 0. Very high scores do not measure how autistic someone is or how much support they need. The AQ was built to describe traits, not to grade people.
Frequently asked questions
What is the AQ test cut-off?
The original authors used 32 or more as a research threshold, met by 80% of autistic adults and 2% of controls in their 2001 study. A later study in an adult clinic found 26 worked better for screening referrals. Neither score diagnoses autism.
What is the maximum score on the AQ?
The maximum is 50, one point per statement. Totals near 50 are uncommon. A higher score does not indicate a stronger form of autism or higher support needs.
Is an AQ score of 26 high?
It is above the general population averages reported in the original study and equals the threshold one clinic study recommended for referral screening. It is a reasonable prompt to reflect further or talk to a professional, not a result in itself.
