Framework provided in response

Relationship and difference

• Understanding concerns whether the learner can make sense of a concept: what it is, why it works, and which relations or mechanisms matter.
• Mastery concerns reliable performance: whether the learner can use the concept accurately, independently, and flexibly in relevant tasks.
• Understanding is usually a foundation for mastery, while attempts to apply a concept expose gaps and deepen understanding.
• Mere repetition or fluent explanation is insufficient evidence of either robust understanding or mastery.

Working hierarchy of mastery

Level	Label	Observable evidence
1	Exposure / recognition	Recognises a term or procedure when seen.
2	Understanding / explanation	Can explain the idea, relation, or procedure in their own words.
3	Guided application	Can complete a familiar task with an example, prompt, or model.
4	Independent proficiency	Can complete typical tasks accurately and reliably without prompts.
5	Transfer / flexible mastery	Can select and adapt the idea in unfamiliar, changed, or complex situations.
6	Creation / teaching	Can evaluate alternatives, diagnose errors, improve an approach, and teach it to another person.

Important qualification

The hierarchy is a practical diagnostic model, not a claim that every topic must reach level 6. The required level depends on the learner’s real use case.

Evidence status
