Declarative scores come from evaluations performed directly on policies. For a perimeter to have a declarative score, it must be associated with a policy and at least one evaluation must be performed for this perimeter on this policy (the score of the last evaluation is used).
💡 The score depends on the response of your evaluation and the scale used.
On the example below, if I take my maturity scale, my score will be 0, 25, 50, 75, or 100. On the compliance scale, my score will be 0 (non-compliant response) or 100 (compliant response).
