Where it fits

- When delayed assessment and optional scheduling are available.
- Avoid it when
- When browsing changing information without a defined retention target.
How to build it
- Identify the knowledge or skills to retain.
- Offer an editable review schedule and postponement.
- Assess variant questions after an equal retention interval.
Measure
- Main metric
- Share of eligible learners using the skill after a defined delay
- Guardrail
- Schedule burden and review-reminder opt-outs
- How to measure
- Allocate comparison groups before exposure and use equal follow-up and eligibility. Track Share of eligible learners using the skill after a defined delay alongside Schedule burden and review-reminder opt-outs.
When it backfires
Do not equate visits with learning or penalize postponement.
