Most workplace training follows the same pattern: a big session, lots of information, and then nothing. People leave with good intentions, and within a few weeks many of the details have faded. This is not a failing of the trainees. It is simply how memory works. Without review, newly learned information fades quickly, a pattern often described as the forgetting curve.
Spaced repetition is the practical answer. Instead of teaching something once and hoping it sticks, you bring it back at increasing intervals. Each review strengthens the memory and makes the next one last longer.
The core idea
The principle is simple: reviewing information right before you would naturally forget it is more effective than reviewing it over and over in one sitting. Cramming feels productive in the moment, but spaced practice leads to more durable learning.
There is a second effect working in your favor. Retrieving information, by actually trying to answer a question rather than rereading notes, strengthens memory more than passive review. So the most effective reviews are short quizzes, not summary emails.
Building a simple spacing schedule
You do not need special software or complicated algorithms to apply spaced repetition at work. A simple schedule works well:
- Day of training: End the session with a short quiz on the key points.
- A few days later: Send a quick review of three to five questions.
- About a week later: Another short review, mixing in questions people struggled with.
- A few weeks later: A final check on the most important points.
Each review should take only a few minutes. The goal is frequent, light contact with the material, not another training session.
Tip: Put the review dates in your calendar when you schedule the original training. If you wait until afterward, it is easy for the follow-ups to slip.
Choosing what to repeat
Not everything from a training session deserves spaced review. Focus on:
- Critical knowledge that people must get right, such as safety steps or key compliance rules
- Things used infrequently that people will need to recall months from now
- Common mistakes you saw in the original session's results
Skip anything people use daily. Their work already provides all the repetition they need.
Writing good review questions
Review questions should make people retrieve the answer, not just recognize it. A few approaches:
- Ask people to apply the idea to a new example rather than restate a definition.
- Use fill in the blanks questions for key terms or steps in a procedure.
- Use sorting questions to have people put the steps of a process in the right order.
- Rotate the wording between reviews so people cannot simply memorize answers to specific questions.
After each review, share the correct answer with a short explanation. The feedback is part of the learning.
Fitting reviews into the working week
The biggest obstacle to spaced repetition at work is not design. It is getting people to actually do the reviews. Make it easy:
- Keep each review very short, and say how long it will take.
- Send it at a sensible time, not in the middle of a busy period.
- Use the first few minutes of existing team meetings for a quick live review.
- Show people their scores so the reviews feel rewarding rather than like a chore.
Managers can make a big difference here. A team lead who opens the weekly meeting with a two-minute quiz on last month's training sends a clear signal that the content matters.
Using the results
Each round of reviews gives you useful information. If a particular question keeps tripping people up, the original training likely needs a better explanation or example. Over time, these insights help you improve the training itself, not just reinforce it.
Spaced repetition with LetMeAdd
LetMeAdd makes it easy to run reviews without extra admin:
- Create self-paced quizzes that people answer on their own time from a link, with scores so they can see how they did.
- Use multiple choice, fill in the blanks, sorting, matching, and find a number questions for retrieval practice.
- Run quick live reviews at the start of team meetings, with participants joining using a 6-character code or QR code and no account needed.
- Review results for each session separately and export them to spot topics that need reinforcement.
- On the Pro plan, use AI question generation to draft fresh versions of review questions, then review and edit them before adding.

Training that is delivered only once is usually forgotten. A few minutes of spaced review turns a one-off event into lasting knowledge.
