Free Enneagram test.

Edition: [email protected]. This preserves the earlier AgentTune adaptation. Full questions, scoring and adaptation notes · Sources and terms. Results are self-reports, not diagnoses; review any suggested preferences before using them.

Machine-readable: the full spec (all items + scoring) is also served as plain Markdown at /tests/enneagram.md — fetch that for a clean, no-JS copy.

Below is AgentTune’s 36-item OEPS-derived adaptation — items, type mapping, scoring algorithm, output mapping. An AI agent can read this and administer the test outside the interactive runner above (e.g., when the user is in a chat conversation rather than on this page).

Developers: download the question JSON and reusable JavaScript scorer in the Enneagram developer resource. The upstream OEPS has 54 items; this site uses a 36-item adaptation.

Open Enneagram of Personality Scales (OEPS), via Open Psychometrics Project. Instrument-specific source terms apply; see the notices above.

The 36 items

Four items per Enneagram type, presented in type order (items 1–4 are Type 1, 5–8 are Type 2, …, 33–36 are Type 9). User rates each statement on a 1–5 Likert scale: 1 = Strongly Disagree, 2 = Disagree, 3 = Neutral, 4 = Agree, 5 = Strongly Agree. No reverse-scored items.

Item → type mapping

Each item awards points to exactly one type. There are no reverse-scored items — the user's raw 1–5 response is the item's contribution to that type's total.

Scoring algorithm

Equal highest scores are reported together, without choosing a dominant type or automatically exporting a tuning. Choose a style explicitly from the linked library pages. Enneagram wings apply only to a unique dominant type.

1. For each of the 9 types, initialize a running total = 0.
2. For each of the 4 items in that type, add the user's 1–5 response directly (no reverse-scoring).
3. Each type ends with a total between 4 (all 1s) and 20 (all 5s).
4. Dominant type = the type with the highest total. In a tie, prefer the lower-numbered type (more common in adults).
5. Wing = the adjacent type (dominant ± 1, wrapping 9↔1) with the higher total. If the two adjacent totals tie, omit the wing.
6. Profile code = {dominant}w{wing} (e.g. 5w4, 8w9). If no wing, just {dominant}.
