Calculation audit
Component values are normalized to 0–10. Contribution is the component value multiplied by its weight. Displayed values are rounded; canonical calculations retain full precision.
10 − Attention Intensity (3.5971)| Component | Value | Weight | Contribution |
|---|---|---|---|
| Visual Motion | 10.0000 | 25% | 2.5000 |
| Visual Change Frequency | 1.8721 | 15% | 0.2808 |
| Brightness Variability | 0.0000 | 10% | 0.0000 |
| Audio Intensity | 1.9893 | 15% | 0.2984 |
| Audio Event Frequency | 0.6792 | 10% | 0.0679 |
| Reward Activity | 3.0000 | 15% | 0.4500 |
| Attention Prompts Interruptions | 0.0000 | 10% | 0.0000 |
The component sum is attention intensity, so it is inverted for the public Calmness score.

Learning value calculation
(skill_demand + agency + depth + transferability) / 8 * 10
App score = weighted mean of activity scores by share of the accessible experience.
explicit academic and guided skill practice
| Component | 0–2 value |
|---|---|
| Skill Demand | 1.80 |
| Agency | 1.20 |
| Depth | 1.50 |
| Transferability | 1.90 |
The four activity components are equally weighted. Learning Value measures demonstrated interaction demands, not proven learning outcomes.
Mode: Explicit academic and guided skill practice
The representative activities involved:
Learning Value reflects demonstrated skill demand, agency, depth, and transferability. It is not evidence of learning outcomes.
Common questions
Khan Academy Kids received a Calmness score of 6.4/10. Higher scores indicate lower measured attention intensity. The score combines visual motion and change, brightness variation, audio intensity and frequency, rewards, and interruptions.
Khan Academy Kids received a Travel score of 7.3/10. This combines offline functionality and reliability, preparation burden, audio independence, commercial interruptions, and accessible content breadth.
Khan Academy Kids received a Learning Value score of 8.0/10 based on representative activities. The score measures skill demand, agency, depth, and transferability; it does not claim proven learning outcomes.
