Scoring Methodology

How the AIGDER instrument transforms qualitative feedback into quantitative educational insights.

* "Prefer not to answer" selections are excluded from the denominator in all average calculations.

Hierarchical Aggregation

  • 1
    Item Level

    Raw input from 22 questions.

  • 2
    Pillar Scores

    Average of all items belonging to a specific pillar (e.g., Content Quality).

  • 3
    Overall Index

    The mean average of the 5 pillar scores.

The Formula

Pillar_Score =
(Σ Item_Scores) / Count_Answered
Overall_Index =
(P1 + P2 + P3 + P4 + P5) / 5

Interpretation Bands

Scores are categorized into four performance bands to aid in decision-making.
