The Forgetting Curve: Design Reviews That Make Training Stick
Use the forgetting curve to plan short, spaced reviews after training or reading, and build recall and practical application into team routines.

Plan for Forgetting to Make Learning Useful at Work
The central point of the forgetting curve is that people forget what they learn as time passes. The practical issue is how to design review around that tendency.
Learning needs more than a single attempt to remember everything. Opportunities to recall material the next day, a week later, and again afterward help turn it into knowledge that can be used at work.
What Is the Forgetting Curve?
Ebbinghaus's forgetting curve describes the tendency for memory to fade over time. Material remembered immediately after learning can fade quickly if left untouched.
The idea highlights several points:
- Newly learned material is not yet stable in memory
- Considerable forgetting can happen during the first day
- Knowledge left unused becomes difficult to apply at work
- Opportunities to recall material improve retention
The value of training or reading therefore depends on what remains several days later, beyond the satisfaction felt at the time.
Why Learning Fades
How people learn often contributes to forgetting. Alongside individual effort, consider the learning process itself.
Training Ends When the Session Ends
Participants may feel they understand a training session yet remember little the following week. This is a common experience.
Training with poor retention often has these features:
- Too much information
- No follow-up check
- No opportunity to use the material at work
- No reflection with a manager
When training ends as a one-off event, the learning may remain in records without appearing in behavior.
Reading Stops at the Last Page
Immediately after reading a book, you may feel you understand it. A few days later, explaining the main points can be surprisingly difficult.
Review how you handle the memory, alongside how much you read. If reading is the final step, the information may simply pass through your mind.
On-the-Job Training Happens Only Once
The same issue occurs in on-the-job training, or OJT. Assuming that someone remembers because they were taught once can leave gaps a few days later.
Without a follow-up opportunity, the learner may begin work without realizing which parts remain unclear. This can cause mistakes and rework.
Review Intervals That Support Retention
When applying the forgetting curve at work, review intervals matter. Short opportunities to recall material at spaced intervals can be more useful than one long review.
Review the Next Day
The day after learning is a useful point for the first review. Recalling the material once at this stage can change how it fades.
Possible activities include:
- Write down three main points
- Explain the material aloud to someone
- Take a short quiz
- Name one point you can use at work
At this stage, the act of recall matters more than perfect reproduction.
Return to It a Week Later
Follow the next-day review with another encounter a week later. Revisiting the material helps it remain available.
Useful methods include:
| Review method | Activity |
|---|---|
| Verbal sharing | Briefly explain what you learned |
| Practice report | Describe what you used at work |
| Question session | Share unclear points |
| Another quiz | Identify gaps in the main points |
Connecting the material with actual work helps turn memory into practical use.
Repeat at Increasing Intervals
Afterward, create opportunities to recall the material after two weeks, a month, and longer intervals. Recalling it after some time has passed can support memory better than rereading the same material every day.
Include time to remember without looking at the material, alongside rereading. This active recall helps the learning become more firmly established.
Build Retention into Training Operations
When review depends entirely on individual effort, it is easily postponed. Organizations need to build it into their routines.
Schedule Follow-Ups in Advance
Set follow-up dates when scheduling the training itself. Leaving the arrangements until afterward makes them less likely to happen.
Include:
- A next-day review of the main points
- Sharing practical applications a week later
- A manager meeting a month later
These three appointments can substantially change how the training is treated.
To connect a review schedule with daily action, see Designing Actions That Sustain Habits. It explains how to establish a consistent cue instead of relying on spare time.
Involve the Manager
A manager's involvement affects whether learning is used on the job. Training that is never mentioned afterward tends to lose priority in the workplace.
A manager can ask:
- What did you learn?
- What did you try at work?
- Where did you get stuck?
- What will you continue next?
These conversations keep the learning connected to the work.
Teach OJT in Smaller Portions
Giving a large amount of information at once can reduce retention in OJT too. Smaller portions followed by checks the next day and a few days later tend to work better in practice.
Teach less at a time and check more often. This is particularly useful when training new employees.

Frequently Asked Questions
Q: Does review need to take a long time?
A: No. Even short opportunities to recall material the next day or a week later can make a difference. The intervals matter more than the duration.
Q: There is too much training content. What should I review?
A: Choose the important points you will use at work. Narrowing them to three main points can improve retention.
Q: Can I apply the forgetting curve to reading?
A: Yes. Write down the main points afterward, explain them the next day, and revisit them a week later. The lasting value of a book comes from what remains after reading.
Q: What if I cannot keep reviewing?
A: Depending on your mood makes consistency difficult. Include review in meetings or one-to-one appointments to make it part of an established routine.
