Protocol
Space review for when the knowledge must last
A smooth second reading can arrive too soon to tell you much.
When it fits
- You need information next month, not only at the end of today's study session.
When to avoid it
- No fixed set of day intervals is optimal for every learner, subject and retention goal.
Why it matters
Plan returns to the material across time instead of concentrating all review in one sitting. Spacing research shows that useful gaps depend partly on how long the knowledge must be retained. Start with a realistic review schedule, then adjust it using actual recall rather than treating a popular interval sequence as a law.
Steps
- Name when you expect to need the material again.
- Schedule a later attempt without the answer visible.
- Use the result to decide what needs another review or renewed explanation.
An example
Preparation for an assessment in several weeks needs returns across those weeks, not seven rereads tonight.
Check your result
The schedule contains delayed attempts, and those attempts influence later review.
Keep this limit in mind
- No fixed set of day intervals is optimal for every learner, subject and retention goal.

Evidence and sources
Cepeda and colleagues found that the review gap associated with better later fact retention depended on the intended retention interval.
The authored scheduling questions are an application, not a validated individualized spacing algorithm.
