Score normalization process

When ratings use more options than the maximum five by five that can be represented on the Talent Plan Tile, or the three by three that can be represented by the 9-box grids used on the Talent Plan Detail view, Sage People uses a normalization process to map the larger number onto the smaller.

To map one rating scale on to another with fewer divisions:

Process step Example
  1. Multiply the number of divisions in each scale together.

Mapping a scale with seven divisions onto a scale with five:

7 x 5 = 35
  1. Split the product into two groups of ranges by dividing the product by each of the two scale numbers.

5 scale: 1-7, 8-14, 15-21, 22-28, 29-35

7 scale: 1-5, 6-10, 11-15, 16-20, 21-25, 25-30, 31-35
  1. Take the mid-points of each range in the group representing the scale with the most divisions.

7 scale: 3, 8, 13, 18, 23, 28, 33
  1. Map the mid point values onto the appropriate range in the group representing the scale with the fewer divisions.
