How Our Enneagram Test Works – Methodology

We believe you should be able to see how a test reaches its conclusions. This page explains how our Enneagram test is built, how it is scored, and what it can and can't tell you.

What the test measures

The test estimates five things: 1. Core type: which of the nine Enneagram types best matches your motivations. 2. Wing: which of the two neighbouring types is stronger for you. 3. Instinctual stacking: the order of your self-preservation, social and one-to-one instincts. 4. Subtype: your core type combined with your dominant instinct (27 possibilities). 5. Tritype: your strongest type in each of the three centers.

The question bank

Our question bank contains 212 original items, written for this test. Each item is designed to reflect the motivation of a particular type or instinct rather than a surface behaviour. The bank includes: - Agreement statements rated on a five-point scale from "strongly disagree" to "strongly agree." - Reverse-worded statements that describe the opposite of a type's pattern. These help detect people who agree with everything and balance the scoring. - Scenario questions that ask how you would react in a realistic situation, with options linked to different types. - Either/or questions that ask you to choose between two descriptions, which is useful for distinguishing similar types and instincts.

The Quick test uses 45 items, and the Full test uses 120 items. The Full test contains every Quick item, so you can continue from Quick to Full without repeating questions. Items were selected to give each type and instinct balanced coverage and to separate commonly confused types.

How answers are scored

• Each agreement answer is converted to a value from −2 (strongly disagree) to +2 (strongly agree). Reverse-worded items count in the opposite direction.
• Each scenario or either/or answer adds points to the types linked to the option you chose.
• For each type and instinct, your total is converted to a percentage of the range that was possible given the questions you answered. This means Quick and Full results are on the same 0–100 scale.
• Core type is the type with the highest percentage.
• Wing is whichever neighbouring type scores higher. If the two wings are within five points, we note that your wings are balanced.
• Instinctual stacking is the order of your three instinct scores.
• Tritype is your core type plus the highest-scoring type in each of the other two centers.

Confidence levels

We report a confidence level based on how far your top type is ahead of the next: - High: 10 or more points ahead. - Medium: 5 to 10 points ahead. - Low: less than 5 points ahead. In this case we tell you that you are "leaning" toward your top type and suggest comparing it with your runner-up.

Consistency check

Some people tend to agree with most statements regardless of content. We check whether you agreed with both a statement and its reverse for the same type. If this happens often, we flag your result as less reliable and suggest retaking the test with fresh eyes.

How we tested the scoring

Before launch, we tested the scoring with simulated respondents: computer-generated answer patterns for every combination of core type, wing and instinct, with different amounts of random noise added to mimic real-world inconsistency. In these simulations, both test lengths reliably recovered the intended core type when answers were consistent, and the Full test remained more accurate as noise increased. These are simulations, not studies of real people. Real-world accuracy depends on self-awareness and honesty, and we will publish feedback-based figures only once enough people have rated their results.

What our test is not

• It is not a clinical or diagnostic tool.
• It is not affiliated with any Enneagram institute, school or trademarked instrument.
• It is not suitable for hiring, selection or any high-stakes decision.

Limitations

The Enneagram is a popular framework with a long tradition, but the scientific research on it is limited and mixed. Self-report tests can be influenced by mood, self-image and how you interpret a question. Tritype, in particular, is a newer extension that is not universally accepted. We encourage you to read about your top two or three types and to decide for yourself which one explains your motivations best.

The optional AI report

Our optional paid report is generated by an AI model. The model is instructed to write only from our Enneagram knowledge base and your actual answers, and each report is checked for completeness and content safety before it is shown. Reports are clearly labelled as AI-generated content. They are for reflection, not advice.

Your data

We store answers anonymously, without IP addresses, so your result link works and so we can improve the test over time. You can delete your result using the link on your result page. See our privacy policy.

Synthetic simulation results

These figures come from computer-generated respondents, not studies of real people. Noise is an artificial simulation parameter. They are not a claim about real-world accuracy.
