As shown in the illustration above ‘Example 1 H2’, the first score formulas that will be defined are Score 1.1, Score 1.2, Score 2.1 and Score 3. Also, every score is split into two parts: Numerator and Denominator. This is due to the following reason.
In HNQIS, Scores ‘Scores’ are usually divided in Subinto ‘Sub-scoresscores’, however, those ‘Sub-scores’ are not directly used to calculate the Main Scores‘Scores’, for example, scores 1.1 and + 1.2 would not define score 1.
Scores ‘Scores’ are calculated from the results of the ‘Q' questions within sub‘Sub-scoresscores’, not the sub-score itself'Sub-score’ themselves.
This is the reason why every score is split between Numerator and Denominator so that those values can be re-used in the Scoring Formulas of all the upper scores‘Scores’.
Use of Program Rules vs Program Indicators

Splitting the main Scoring Formula in the Numerator and Denominator formulas results in the following set of formulas:
About the Numerator and Denominator. In reality, both the Numerator and Denominator are also split in two parts: Critical and Non-critical. The sum of the Critical Numerator and Non-critical Numerator equals the Numerator of the score, the same applies to the Denominator of the score. This separation of Critical and Non-critical is mainly used for the Assessment Score and the Competency Class calculations, every other score uses the combination of Critical and Non-critical questions. The use of this distinction will be further explained in the Calculating the Critical and Non-critical Scores. In this example, we will assume that every question is Critical.

Now, Score 1.1 which contains questions Q1, Q2 and Q3 would have the following set of formulas:
For Score 1.2 containing questions Q4, Q5, Q6 and Q7 the set of formulas would be the following:
The same process would be repeated for Score 2.1 and Score 3, which also only contain questions.
