Normalized rating distribution score
Each appraisal's overall rating is recalculated into a normalized rating distribution score, which is used to include the rating level range in calculating the percent level.
The calculated value for each rating distribution level is the percent level indicated in the shaded blue bar that represents the Y-axis of the chart.
The normalized rating distribution score is calculated using percent normalization calculation or linear normalization calculation, depending on the specified normalization calculation method in the appraisal form that is associated with the employee.
See Performance appraisal score calculation.
Administrators can specify the normalization calculation method in the overall rating section when they create an appraisal form.
