Why do employees forget so much after a training?

An employee can answer virtually every important question correctly at the end of a training. A few weeks later, that can look very different. That does not automatically mean the training was bad: it mainly means learning and remembering are two different things.

The training day is just one moment

A training often concentrates a lot of information into a relatively short period. Participants listen, practise, ask questions, and process new information. Then everyone goes back to work: the context changes, new information comes in, and other tasks take priority. Without further repetition, it becomes progressively harder to independently recall specific knowledge, a pattern known as the forgetting curve.

Reading is not the same as remembering

A common way to maintain knowledge is having people read information again. But there is a difference between recognising and actually being able to recall. When someone sees an answer again, it can look familiar, without that person being able to produce the answer independently. That is why it is more valuable to not just have employees re-read information, but also actively answer questions, for example: 'What is your first action for an emerging fire?' or 'Which step should you never skip in this situation?' The employee then has to actually retrieve knowledge from memory, instead of recognising it.

Repetition doesn't have to be big

Maintaining knowledge does not require a second training day. A short exercise can already be enough to reactivate existing knowledge, spread over several weeks:

• Week 1: three short questions
• Week 2: a practical scenario
• Week 3: a short quiz
• Week 4: a situation where the employee has to make a decision

This way, knowledge is regularly retrieved again without employees needing to take a full course again. See also how often you should really repeat knowledge.

From forgetting to maintaining

The question should not only be how you deliver a good training, but also how you make sure employees keep using what they learned. That second question is often overlooked, and that is exactly where the opportunity lies for organisations and training providers. Stiqqo activates participants after the training with short, weekly five-minute moments, so knowledge stays active instead of quietly fading.

Conclusion

Forgetting is not a sign that people cannot learn: it is a normal part of memory. The solution is therefore not simply 'more training'. The more interesting question is: how do you design the learning process so that important knowledge is regularly retrieved and applied again? That is where knowledge retention begins.
