By default, normalization occurs when the form template is using two different point of the rating scale. If you want to use un-normalized score such as 3.5 as the overall form rating, for example, you need to to set the flag to FALSE.

Calculation Process for Normalization in the Competency section

Sample Rating Scales in the Form template:

  • Goals Rating Scale (0.5 - 5) point scale
  • Competency Rating Scale (1 - 5) point scale

Normalized Calculation for Competency:


(((section rating - original min)/(original max - original min)) * (new max - new min)) + new min

((3.5-1)/(5-1))*(5-0.5)) + 0.5 = 3.3125

Calculate Overall Form Rating:


    ((3.3 * .70) + (3.3125 * .30)) / (.70 + .30) = 3.3

Note: Sceenshots are based from demo instance.



To Enable or Disable Normalization

      The <normalize-section-rating> of <fm-sect-config> enables/disables rating normalization at respective section level. If <fm-sect-config> element at form level one is not configured, the child element by name meta-normalize-form-rating is introduced in <fm-meta> to enable/disable normalization for overall form rating. Again the values supported by this element are true/false, default is true.

How to Disable Normalization Calculation Per Section?

Add this attribute <normalize-section-rating> in the <fm-sect-config> of every section (Objective, Competency, Objective-Competency summary, Summary) then set the flag to false.
