Reviewed by Gildas Garrec, CBT practitioner
Good morning,
This test looks at impostor syndrome: constantly questioning whether you deserve your place, dreading being found out, crediting your successes to anything but yourself, and comparisons that always seem to go against you. The report shows which of these patterns drives the others, and in which situations the mechanism kicks in.
What you receive — a report written from your answers: what stands out, what sustains it, and where to start. This week, this month, later on.
How it is built — each axis is analyzed on its own, then cross-read with the others, through clinical reading frameworks. Your detailed answers are attached as an appendix. See an example report
The test runs over 63 questions and takes about 10 min, for a price of $3.60.
We'd also suggest reading the book The Practical CBT Guide, to take this reflection further. It's included in the price and downloadable.

QUICK ANSWER
Impostor Syndrome Test: Self-Doubt and Legitimacy — a 63-question self-assessment, about 10 min. This test looks at impostor syndrome and at the mechanism that makes you doubt your own legitimacy. Once finished, you receive a detailed PDF report ($3.60): an interpretation of its 5 dimensions, a radar chart, up to 18 clinical reading frameworks and a personalized action plan. It is designed to help you know yourself better.
This interactive test covers doubts about your own worth, the fear that your weaknesses will be discovered, how you explain your successes, comparing yourself with others, and readiness to change. What the test asks, for example Self-doubt Whether, even with a good result in hand, on an exam or a project, you doubt your abilities. Whether you rely on your skills without feeling like you're bluffing. The fear that your weaknesses will show Whether, when you make a mistake in front of a group, you feel like everyone is about to see through you. Whether you stay calm when someone goes over your work line by line. How you explain your successes Whether everything you've achieved so far comes down mostly to luck and timing. Whether, when you get a good result, you can name the choices that led to it. Comparison Whether you compare yourself to the people you learn or create with, and their skills seem greater than yours. Whether you measure your worth by your own path, without comparing it to anyone else's. Readiness to change Whether what you've just described weighs on your daily life. Whether you want to change the way you function day to day.
About this test
▼
Dimensions assessed
- ●Your reading of this feeling of illegitimacy- How you explain this feeling of not belonging, before the test tells you anything. This section measures no difficulty and produces no level: it records your starting point.
- ●Persistent self-doubt- The gap between the skills others can see in you and the ones you give yourself credit for. That gap is what the report measures, not your actual level, which no questionnaire could establish.
- ●Fear of being exposed- What the idea that a shortcoming might be noticed stirs up in you. This axis looks at anticipating being found out, the core mechanism of the pattern this test describes.
- ●External attribution of successes- The mechanism by which a success gets credited to something other than you. The report pinpoints your default explanation here, the one that comes before any closer look.
- ●Unfavorable comparison- The yardstick you measure yourself against, and how that comparison usually turns out. This dimension assesses the process itself, not the people you compare yourself to.
- ●Readiness to Change- Measures your current readiness to acknowledge the impact of this topic on your life and engage in a process of growth.
