Questions
Is this an official type assessment?
No. Quaterna is independent and not affiliated with any test publisher. It is built on Jung's four public preference pairs and cognitive functions, with its own questions, scoring and profiles.
Do I need an account?
No. The test and report work signed out, and your answers survive a refresh. Sign in only if you want to save reports to your account.
What do the percentages mean?
How far your answers lean toward one side of each pair. 50% is an exact tie; 100% means every item was answered strongly toward that letter. Under about 57% the letter is a close call, and the report lists neighbouring types worth reading too.
How accurate is it?
Treat it as a mirror, not a verdict. Type is a description of preferences, not abilities, and a short self-report can shift with mood and context. If a letter was a close call, read both profiles and pick the one that sounds more like you.

An independent, educational personality test. Not an official assessment and not a clinical or hiring tool.
