Enneagram tests

The enneagram describes nine distinct ways of seeing the world, relating to others, and handling everyday challenges. Unlike models built around observable behavior, it digs into the motivation underneath: the fear and core desire driving every decision.

Each type chases a different strategy: Type 1 seeks to do things correctly; Type 2, to feel needed; Type 3, achievement and recognition; Type 4, an authentic identity; Type 5, understanding before acting; Type 6, security; Type 7, new experiences; Type 8, independence and control; Type 9, peace and harmony.

The RHETI: the academic reference questionnaire

The reference academic questionnaire for identifying your dominant type is the Riso-Hudson Enneagram Type Indicator (RHETI), created by Don Richard Riso and Russ Hudson. Beyond your main type, it flags how much each of the other eight types influences you. Its nine types carry the names we use throughout this site: the Reformer (1), Helper (2), Achiever (3), Individualist (4), Investigator (5), Loyalist (6), Enthusiast (7), Challenger (8), and Peacemaker (9).

Knowing your type isn't about squeezing yourself into a label, it's about spotting your automatic pattern under pressure or inside your relationships. Here you'll find the quick enneagram test (10 questions, under 2 minutes) and the full enneagram test (144 questions), plus articles on each type. Neither replaces a professional psychological assessment or academic questionnaires like the RHETI.

Origin: from the Arica School to Riso-Hudson

The modern personality system traces back to Bolivian teacher Óscar Ichazo, founder of the Arica School, who in the 1960s first linked the nine points of the enneagram symbol to nine personality fixations. Chilean psychiatrist Claudio Naranjo later carried it into clinical practice and helped popularize it in the therapy world. Decades later, Riso and Hudson built on that foundation to create the psychometric instrument (RHETI) used today.

Its scientific standing, compared with the Big Five

Unlike models such as the Big Five, the enneagram doesn't currently have a peer-reviewed, standardized instrument equivalent to the NEO-PI-R. A systematic literature review published in 2021 in the Journal of Clinical Psychology by Hook, J. N. and colleagues found that the nine-type structure hasn't been consistently replicated across the available factor-analytic studies. That doesn't take away from the enneagram's value as a tool for self-reflection and a shared language for talking about motivation and behavior patterns, but it does call for treating it with the same caution owed to any popular-science model: useful for thinking about yourself, without the same empirical backing as other personality models on this site.
