The Assessment Tree illustration below ‘Example 1’ (see Example 1) shows a typical structure of a H2 Assessment, which includes the Scores, Sub-scores and their retrospective questions.
...
As shown in the illustration above ‘Example 1’, the first 'Score' formulas that will be defined are;
...
In HNQIS, ‘Scores’ are divided into ‘SubSub-scores’scores, however, ‘SubSub-scores’ scores are not used to calculate the ‘Scores’, for example, scores 1.1 + 1.2 would not define score 1.
‘Scores’ are calculated from the results of the ‘Q' questions within ‘Sub-scores’, not the 'Sub-score’ themselves.
...
In this example, we use the ‘Scoring Formula’ Scoring Formula to obtain the values from Sub-scores 1.1 and 1.2.
...
In this example, we will assume that all questions are ‘Critical’ Critical, however, you would normally be working with both Critical and Non-Critical Questions.
Score 1.1 which contains questions Q1, Q2 and Q3 would have the following set of formulas:
...

The Assessment Score (also referred to as Global Score) is determined by the score of the Critical Questions in a checklist. If a H2 Checklist does not contain at least one Critical Question, the score will be determined by the Non-Critical Questions. |
The Assessment Score Formula is calculated in the same way as a Score containing multiple Sub-scores.

Please note you should give special consideration that the following formula only includes Critical Questions (while the other ones included , whereas, the previous Scoring formulas worked with both Critical and Non-Critical questions)Questions. |
Remember that if a checklist contains only Non-Critical Questions, the Assessment Score will be based on those questions instead of the Critical Questions.
The Numerators and Denominators for each score in the example are the following:
...
Now, using the formula defined in the previous section (see Equation 6),the Assessment Score of this example ends up being:
