How are 360° feedback scores calculated?

The **Competency Matrix** on your 360° feedback dashboard summarises a lot of individual ratings in just a few numbers. This article explains exactly what those numbers mean — how **Ø External** and **σ Deviation** are computed, what the ring around a cell stands for, and how anonymity affects the figures you see.

<img src="https://mintcdn.com/honestly/RC0S9r1e-n8nmUR8/images/a4231d2848d0.png?fit=max&auto=format&n=RC0S9r1e-n8nmUR8&q=85&s=1df0916e1690695cfa9be44f50aca2b2" alt="" width="2578" height="639" data-path="images/a4231d2848d0.png" />

An example Competency Matrix. The **Self-assessment** , **Manager** , **Peers** and **Direct reports** columns each carry one cell per row. **Ø External** and **σ Deviation** summarise the row. The "**–** " cell in **Leadership / Direct reports** is anonymity-restricted; that row's **σ Deviation** is therefore also "**–** ". Rings around cells (**Communication / Peers** , **Leadership / Peers** , **Delegation / Peers**) indicate within-group deviation. The yellow banner appears whenever any cell is restricted.

<Note>
  * All scores in the matrix are shown on the questionnaire's scale (for example **1–5** or **1–10**) and rounded to one decimal place.
  * **Ø External** never includes your **Self-assessment**.
  * **σ Deviation** is intentionally hidden whenever a perspective in that row is anonymity-restricted, so you never see a deviation calculated from an incomplete picture.
  * Within-group deviation (the ring around a cell) is only calculated once a perspective has at least **6** distinct raters.
</Note>

From individual responses to a cell value

Each cell in the matrix represents one **dimension** (a competency) seen from one **perspective** (**Self-assessment** , **Manager** , **Peers** or **Direct reports**).

To compute it, Honestly:

1. Takes every response from that perspective to a question that belongs to the dimension.
2. Converts each response to a value on the questionnaire's scale. This step makes different question types — stars, smileys, NPS, ranked select — comparable.
3. Averages those values.
4. Rounds to one decimal place.

If anonymity removes a question (see below), only the remaining questions in the dimension are used. If anonymity removes every question of the dimension for that perspective, the cell stays blank.

Ø External — your overall external assessment

**Ø External** is the **arithmetic mean of the perspective averages** , with your **Self-assessment** excluded.

`Ø External = average of ( Manager score, Peers score, Direct reports score )`

Two things are worth knowing about this number:

* **Perspective groups count equally.** A peer group of ten people contributes one number to **Ø External** , the same as a single manager. The cell value for each perspective has already averaged out the individual raters before it reaches this step.
* **Anonymity-restricted perspectives are simply skipped.** If, say, the Direct reports perspective falls below its anonymity threshold, **Ø External** is the mean of **Manager** and **Peers** only.

If no external perspective has a score, **Ø External** is blank for that row.

σ Deviation — how consistently you are perceived

**σ Deviation** measures how far apart the perspective scores in that row are. It is the **standard deviation of all perspective scores** , including your **Self-assessment**.

The figure is shown next to one of three labels:

| Label      | Rule                                                | Meaning                                                                    |
| ---------- | --------------------------------------------------- | -------------------------------------------------------------------------- |
| **Low**    | σ is up to **10%** of the scale range               | Perspectives agree closely. You are perceived consistently across groups.  |
| **Medium** | σ is between **10%** and **20%** of the scale range | Moderate differences between perspectives.                                 |
| **High**   | σ is above **20%** of the scale range               | Perspectives diverge clearly. Different groups experience you differently. |

On a **1–5** scale (range 4) this means: **Low** when σ ≤ 0.4, **High** when σ > 0.8. On a **1–10** scale (range 9): **Low** when σ ≤ 0.9, **High** when σ > 1.8.

**σ Deviation** is intentionally **left blank** when:

* Fewer than two perspectives have a score in that row, or
* **Any** perspective in that row is anonymity-restricted — even if the other three would be available. A deviation calculated from a partial set of perspectives would be misleading, so Honestly does not show one.

A **High** deviation is not automatically a problem; it simply tells you that different groups see you differently and that the row is worth a closer look.

The ring around a cell — agreement within the perspective

While **σ Deviation** compares perspectives against each other, the **ring around a cell** tells you how much the raters **inside one perspective** disagreed with each other.

* The ring only appears when that perspective has at least **6** distinct raters. Below that, no ring is shown — not because everyone agreed, but because the group is too small for a reliable spread.
* The exact mean, the response count and the within-group deviation are shown in the cell's tooltip.

How anonymity affects the numbers

Anonymity is enforced **per perspective, per question** , by comparing the number of distinct raters to that perspective's threshold. The effects cascade through the matrix:

| What you see                                                     | When it happens                                                                                            |
| ---------------------------------------------------------------- | ---------------------------------------------------------------------------------------------------------- |
| A cell shows **–**                                               | Every question in that dimension for that perspective fell below the threshold.                            |
| **Ø External** is computed but excludes one or more perspectives | At least one non-self perspective is anonymity-restricted but another non-self perspective still has data. |
| **Ø External** is blank                                          | No non-self perspective has data left.                                                                     |
| **σ Deviation** is blank                                         | Any perspective in that row is anonymity-restricted, **or** fewer than two perspectives have a score.      |
| Yellow banner above the matrix                                   | At least one cell in the matrix is anonymity-restricted.                                                   |

The rule of thumb: anonymity **blanks** a value, it never substitutes one.
