# Calculating and publishing the gender equality index

The **Gender equality index** tab calculates the professional gender equality index of each database from Illizeo’s history. HR review each indicator, correct what Illizeo does not know with a justification, describe the corrective measures when the score requires them, then publish the index to the mandatory display. This article follows these steps; it is intended for HR and for those who publish the index, and explains what members of the works council (CSE) see.

## Before you start

- The BDESE module must be installed for your workspace and opened to you. The tab is reached through **BDESE › Gender equality index**.
- Calculating, correcting an indicator and filling in corrective measures require the **BDESE data entry** right at Execute level. Publishing requires **BDESE publication** at Execute level. The Egapro summary can be downloaded with either of these two rights.
- CSE members and experts only see published indexes.
- You only see the databases of the entities your role covers.
- For the pay indicator to be calculated, the year’s remuneration must be available: see [BDESE payroll data](https://illizeo.com/en/centre-aide/bdese-payroll-data/).

The index’s scales, thresholds and brackets come from the law pack published by Illizeo. If that pack does not describe the index yet, the tab says so and nothing is calculated. If it is pending legal review, a notice asks you to check the results before declaring.

## Reading the calculated years

The **Calculated years** card reminds you that a year’s index is published the following year, by 1 March at the latest. Its table gives, for each year:

- the **Reference period**, which you can click to open the index;
- the **Bracket**: **50 to 250 employees** or **More than 250 employees**;
- the **Score** out of 100, or **Not calculable**;
- the **Status** (**Calculated** or **Published**) and the calculation date.

A database’s calculated years.

## Calculating a year’s index

1. Click **Calculate**. The “Calculate the gender equality index” dialog opens.
2. Choose the **Reference period**: the previous year by default.
3. Leave the **Workforce bracket** on **Derived from headcount**. Only force it if the headcount known to Illizeo is not the one to declare.
4. Click **Run the calculation**. A message confirms “Index YYYY calculated.”

The calculation reads Illizeo’s history: paid remuneration, salary history, contracts and absences of the year. Recalculating an unpublished year keeps its corrections. A published index is no longer recalculated.

Calculating a reference period.

### Who is counted

- Employees under contract in the database for at least 183 days in the year; apprentices and interns are excluded.
- Paid remuneration, in full-time equivalent, with the same priority as the Payroll tab: Silae, then the imported file, then the Budget actuals.
- Raises, drawn from the base salary history; promotions, as a move to a higher category (workers, employees, technicians and supervisors, managers); returns from maternity leave, drawn from absences with that reason.

## Reading an index

Click a reference period. The “YYYY index — reference period YYYY” card opens, with the database and the bracket.

1. At the top: the **Overall score** out of 100, the **Points obtained**, the **Headcount** and the **Employees counted**. A score below the corrective measures threshold is shown in orange.
2. The **Indicators** card gives, for each one, its **Result**, **In favour of** which sex the gap plays, and its **Points**. The possible indicators are: **Pay gap**, **Gap in individual raise rates**, **Gap in promotion rates**, **Gap in raise rates (promotions included)**, **Raises on return from maternity leave** and **Under-represented sex among the ten highest earners**. Which ones apply depends on the bracket: in the 50 to 250 employees bracket, the index has four, with the gap in raise rates (promotions included) taking the place of the two separate gaps.
3. Unfold an indicator’s “Details” chevron to see its groups (category, age bracket, women, men, gap) and whether they are **Counted** or **Excluded: too few employees**. No amount appears.

The **Catch-up** badge flags a gap that favours the lower-paid sex: the score is then the maximum. A **Not calculable** indicator shows its reason, for example “No remuneration paid for the year: import payroll or connect Silae.” or “No promotion during the year.”. If the calculable indicators are worth too few points, the overall score is **Not calculable**.

An index’s details, indicator by indicator.

## Correcting an indicator

What Illizeo does not know, you correct, as long as the index is not published.

1. On the indicator’s row, click **Correct**.
2. Choose **Corrected result** and enter the **Result** (a number between 0 and 100); for the first four indicators, specify **In favour of**: **No gap**, **In favour of women** or **In favour of men**. Or choose **Indicator not calculable**.
3. Fill in the **Reason**, which is mandatory.
4. Click **Save**.

Points are recalculated on the scale and the row carries the **Corrected** badge, with the date and reason. To go back to the calculated result, reopen the correction and click **Remove the correction**.

## Filling in the corrective measures

Under 75 points, corrective measures are mandatory (art. L1142-9) and are published with the index; the card then shows an orange notice.

1. In the **Corrective measures** card, describe the planned measures.
2. Click **Save the measures**.

## Downloading and publishing the index

### Downloading

- **Egapro summary (CSV)**: one line per item to report (company, bracket, headcount, period, publication year, indicators, points, score, measures).
- **PDF**: the document to display, which anyone who reads the index can download.

### Publishing

1. Click **Publish**. If the score is under 75 points and the measures are empty, the button is greyed out: “Fill in the corrective measures first.”
2. Read the confirmation: the index will be displayed to the employees of the database’s entities on the **Mandatory display** page, replacing the previous year’s, and can no longer be modified.
3. Click **Publish**. The index carries the badge “Published on … — read only”.

Illizeo sends nothing to the authorities: the declaration on Egapro remains for the company to make, from the summary.

## What CSE members see

A member or an expert only sees the published indexes of their database, indicator by indicator, with the announced corrective measures. They can download the PDF; they have no calculation button, no correction and no Egapro summary. Without a published index, the tab shows “No index published for this database.”

## Good to know

- The index for reference period N is published in N+1, by 1 March at the latest.
- A published index can neither be modified nor recalculated.
- Publishing removes the previous index of the same database from the mandatory display.
- A correction always keeps its reason, author and date.
- The same person, if they hold both rights, can calculate and publish the index.
- The legal content follows the law pack published by Illizeo; the screen flags when it is pending legal review. Check the results before declaring.

## Frequently asked questions

### Why is the score “Not calculable”?

The calculable indicators are worth fewer points than the threshold set by the law pack (75 by default). Complete the data (the year’s payroll, salary history) or correct the indicators with a justification.

### Why is the Publish button greyed out?

The score is under 75 points and the corrective measures have not been filled in.

### Does recalculating erase my corrections?

No: as long as the index is not published, a new calculation keeps the corrections.

### The raises indicator is “Not calculable”. What should I check?

The reason shown guides you. “No individual raise during the year.” means no base salary increase is dated in the year on the employee records; “Too few women or men to calculate the gap.” relates to the headcount. If the information exists outside Illizeo, correct the indicator with a reason.
