2529246 - Trend rating calculation when comparing users in Talent Search


This article provides information on how trend ratings (sysOverallPotential, sysOverallPerformance, sysOverallCompetency, sysOverallObjective, sysOverallCustom1 and sysOverallCustom2) are calculated in the Compare section of Talent Search.

Reproducing the Issue

  1. Go to Succession > Talent Search;
  2. Select filters to return target users;
  3. In the Results page, select the users returned;
  4. Click Compare;
  5. In the Compare window, click Configure Fields > Ratings tab;
  6. Select the Trend elements you want to use to compare the selected users:



The trend ratings in the Compare section will use rating normalization, as the system will show the rating labels configured in Admin Center > Matrix Grid Rating Scale. 

Calculating the ranges of the original rating that map to each of the target ratings is a simple process. You need to take the total range from the original scale and divide it by the number of ratings in the target scale, suing below equation:

Range = (maxO - minO) / nTarget


  • maxO = maximum value of original scale
  • minO = minimum value of original scale
  • nTarget = number of ratings in target scale

For example, ratings added to the system through import or calculated ratings from Performance Management forms, with decimal points (e.g. 4.27), in Talent search will be normalized and displayed with the labels configured for the Trend element, instead of the rating number. Using the rating normalization, in a 5 point scale and a user with a rating of 4.27, will have the label configured for the score 5.0 in the Trend element.

For the example above, this would be calculated as below:

Range = (5 - 1) / 5 = 0.8

This number corresponds to the range that will be mapped to each output. We can then build the following scales:

Normalization sample using a 3-point scale (Range = 0.66)

1.0 to 1.66 is equal to score 1 or (Low) in Talent search;
1.67 to 2.33 is equal to score 2 or (Medium) in Talent search;
2.34 to 3.0 is equal to score 3 or (High) in Talent search.

Normalization sample using a 5-point scale (Range = 0.8)

1.0 to 1.8 is equal to 1 or (Low) in Talent search;
1.8 to 2.6 is equal to 2 or (Low-Medium) in Talent search;
2.6 to 3.4 is equal to 3 or (Medium) in Talent search;
3.4 to 4.2 is equal to 4 or (Medium-High) in Talent Search;
4.2 to 5.0 is equal to 5 or (High) in Talent Search.

The trend ratings displayed when comparing users in Talent Search are not configurable, and the system will use normalization method to fit the rating in the scale configured for the element.
