Set up the performance year and calibration framework
Quick answer
- In D365, create one Performance year record per year with its start date, end date and rating model.
- Open the calibration framework for that year and enter the expected percentage of employees in each rating band.
- Those percentages become the expected curve that HR calibrates against at the end of the year.
The performance year ties the whole cycle together — every review period and every generated review belongs to one. It also includes the calibration framework, the expected distribution of ratings HR compares actual results against during calibration.
This is a once-a-year task. Set it up when the school year starts, and it needs no further attention until the next year.
Open the performance year form
In D365, go to the Performance year setup under Human Resources ▸ Performance ▸ Setup ▸ Performance year.

Create the year
Create a single record for the year and set:
Field What it holds Start date The first day of the performance year End date The last day of the performance year Rating model The rating model used across the year — the standard model unless your organisation has its own You can choose the start and end dates, so the performance year can follow the school year rather than the calendar year.
Open the Gaussian curve framework
With the year selected, click Gaussian framework from the Action Pane.
Enter the expected distribution
Enter the percentage of employees expected to fall into each rating band. This is the curve calibration works against — during calibration, HR sees expected against actual side by side, so a band set to 20% showing 30% of employees is immediately visible as a gap.

Set up the framework before the end-of-year reviews are submitted. Calibration has nothing to compare against until these percentages are in place.
Next, divide the year into the stages you will run — see Set up performance periods.
