Big Five Aspects Test (BFAS)
The Big Five Aspect Scales (BFAS) were developed by Colin DeYoung, Lena Quilty and Jordan Peterson in 2007. They split each of the five broad personality traits into two aspects: for example, Neuroticism into Volatility and Withdrawal, and Extraversion into Enthusiasm and Assertiveness. The items are published on the public-domain International Personality Item Pool.
It takes 12 to 15 minutes. Answer as you usually are, not as you'd like to be. Your answers are scored in your browser and never stored or sent. It's for self-reflection, not diagnosis.
Free, no sign-up. Your progress is saved only in this browser on this device, so you can stop and come back later. Nothing is sent to anyone.
Describe yourself as you generally are now, not as you wish to be in the future. Describe yourself as you honestly see yourself, in relation to other people you know of the same sex as you are, and roughly your same age.

What your result can and can't tell you
The BFAS shows broad patterns in how you tend to feel, relate and act. It can't tell you who you should be, and it isn't a diagnosis. Mood, stress and circumstance all colour the answers you give on a particular day.
Your scores are compared with the university sample in DeYoung, Quilty and Peterson (2007): 480 students in Canada, mostly young adults, from varied ethnic backgrounds. "Lower than most" means more than one standard deviation below that group's average, and "higher than most" more than one above. Compared with people of your own age or culture, your result might look different.
The aspects can be more revealing than the five big traits. Two people with the same Agreeableness score might differ a lot: one warm and caring (Compassion), the other careful to respect authority and avoid conflict (Politeness). If you grew up putting family first, that second pattern may feel familiar, and the pages on people-pleasing and boundaries with family might be useful.
Person-centred counselling isn't about fixing your traits. It's a place to understand them on your own terms. You can read more about online counselling for women or book a session.
How the BFAS score works
99 questions, scored as the average of your answers; 45 are reverse-scored. These are the score ranges this page uses to describe your result. Where the questionnaire's authors publish official cut-offs, the ranges follow them; the sources are listed below.

Questions people ask
What's the difference between aspects and facets?
Facets are narrow traits, such as the 30 measured by the IPIP-NEO. Aspects sit between facets and the five broad domains. DeYoung, Quilty and Peterson found that the facets within each domain clustered into two related but distinct groups, giving ten aspects in all. They're a middle level of detail, more specific than the Big Five but simpler than 30 facets.
Are my answers stored anywhere?
No. The test runs entirely in your browser. Your answers and scores aren't saved on a server, sent to me, or shared with anyone. If you close or refresh the page, your answers are gone, so you may want to note down your scores if you'd like to keep them.
How are the bands worked out?
Each score is the average of your answers on a 1 to 5 scale, after reversing the items worded in the opposite direction. Bands use the means and standard deviations reported for the university sample in DeYoung, Quilty and Peterson (2007). Scores within one standard deviation of that average count as around average. Bear in mind it was a group of mostly young students.
Is this the same as the Big Five test?
It measures the same five broad traits, but with different items and a different level of detail. If you'd like facet-level results instead, the IPIP-NEO-120 on this site gives 30 narrower facets. Taking both can be interesting, and small differences between them are normal because each uses its own set of questions.
