Refresher Training: An Ideal Use for AI

Refresher Training: An Ideal Use for AI

One and done. People forget. Little changes. If this sounds like your organization’s approach to employee training, it’s time to consider refresher training. With the help of AI, you can turn the material you already have into engaging and effective refresher modules and quizzes in just a few moments. Follow up with these modules to make learning continuous and more sustainable. This will increase the impact of employee training.

Imagine this: you have developed and rolled out a new employee onboarding or training program but still see employees:

  • making the same mistakes
  • not using software tools correctly
  • not following new or updated policies
  • causing workplace accidents
  • sticking to the old brand values
  • not selling the new products

Why didn’t behavior or mindsets change post-training, you might ask. In this case, it’s time to tackle the problem at its roots.

People forget too much too soon

Employees need to stay updated with the latest knowledge, skills, and regulatory requirements. That’s why businesses invest in training in the first place.

Employee training is a significant investment for companies. The global e-learning market reached USD 316.2 billion in 2023 (Source) and by 2027, the market is projected to reach USD 462.6 billion (Source).

Professionally produced 20-minute e-learning courses cost between EUR 15’000 and EUR 25’000 (Source)

However, employees often struggle to retain and apply knowledge from training programs. The result: Little changes post-instruction.

There are two major reasons why knowledge doesn’t stick:

1. Information Overload

Our brains aren’t made to absorb a firehose of information. Too much information at once leads to overload. Cognitive load theory suggests that human working memory is limited to about 7 ± 2 units of information or “chunks.” More recent estimates suggest this capacity may be around 4 single-item chunks of stimuli that can be processed at once (source).

The consequence: knowledge doesn’t get stored in long-term memory.

What you can do: Break information into bite-sized chunks without overwhelming participants or taking too much time out of their busy days. Make the experience easy to access and use. Microlearning allows you to do exactly this.

2. Forgetting Curve

The term forgetting curve was originally coined by Hermann Ebbinghaus in 1880. It suggests that employees can forget up to 50% of what they learned within an hour if they don’t revisit the material. By the next day, this number can increase to 70%. Up to 90% of information is lost in a week when there is no attempt to retain it (source).

The findings have been replicated in newer studies indicating that around 80% of information is lost within the first six days (source).

Regardless of the exact percentage and time frame, people forget way too much too soon.

While it makes sense to be selective and remember only what is important for work, the numbers show that not refreshing knowledge makes employee training unsustainable.

Or in other words: Why train if they don’t retain?

What you can do: Apply a technique called spaced repetition, which is the foundation of refresher training.

Refresher Training Keeps Knowledge – Fresh

Refresher Training complements larger training programs and builds upon the foundations employees gain in initial onboarding and training. It follows up days, weeks, and months after a workshop, classroom training, or e-learning is done.

Designed to reinforce previously learned information, close knowledge gaps, and introduce new relevant information, it helps employees maintain proficiency and stay updated with industry standards and best practices.

Refresher training keeps employees sharp, compliant, and up-to-date. By revisiting what they have learned, you ensure their knowledge stays relevant.

Regular refresher training helps combat the forgetting curve.

Why Generative AI is Ideally Suited for Refresher Training

Generative AI leverages Large Language Models (LLMs) that represent the vast amount of data they have been trained on. These models learn the patterns, structures, and relationships within the data, specifically the language.

This allows them to generate text that sounds like it was written by a human. Additionally, they can convert existing material, such as training content or even policies, factsheets or guidelines, into new formats.

Read our article about generative AI for Learning & Development to dive deeper into the topic.

Using generative AI to transform existing material into a new format allows you to make better use of existing resources. Repurposing content that has already cost a lot helps protect your initial investment and increases its potential impact.

Moreover, AI can complete the task quickly.

If you wonder what a specialized tool like eggheads can do that ChatGPT, Gemini, or Mistral can’t do out of the box, here’s the answer:

  • First, you need to know how to prompt these AI chatbots (read our tips about good prompting), which takes experience and time. A specialized tool has already solved this step for you. All you need to do is provide the source content which is more convenient and efficient.
  • Second, a specialized tool gives you editorial control. While AI creates the first draft, an AI-enhanced authoring tool like eggheads lets you check the generated content for accuracy and enrich it with videos, images, gifs, or emojis. This way, you avoid the risks of AI errors (hallucinations, bias etc.) and know exactly what your audience will receive.
  • Third, specialized tools handle the entire workflow, from creation to delivery and tracking. For example, with eggheads, you can share AI-generated refresher training modules with staff and track their engagement and participation.

With AI, it’s never been easier to reuse existing training content. You can even create variations for different audiences to personalize the training.

9 Benefits of Refresher Training in HRM

1. Facilitates Adaptation to Change

Helping employees adapt to changes makes it easier for them to handle new rules, technologies, and market shifts. Keeping up with these changes can be hard, but regular updates can help.

2. Improves Performance and Productivity

Regular training builds competence, leading to fewer mistakes and higher-quality work. This makes employees more confident, productive, and efficient.

3. Ensures Safety and Compliance

Frequent reminders help maintain adherence to rules, standards, and safety regulations. Some eggheads customers use short, interactive bursts to keep awareness for IT security, data privacy, and compliance high. Refresher training is a cost-effective method to mitigate risks

4. Helps Remember What Matters

Refresher training concentrates on specific knowledge or skills that need reinforcement. It directs attention to what employees need to know and why it’s important.

As an eggheads customer doing refresher training for compliance put it: “I want staff to know when they need to push the red button”.

5. Reduces Costs

Reinforcing the knowledge from core training protects the initial investment by reducing the need for extensive new training sessions. This approach optimizes existing resources.

6. Empowers a Culture of Continuous Learning and Development

Weaving short and regular refresher training into daily workflows makes learning an integral part of work. Training is no longer a standalone activity that staff or management perceives as time away from work. Regular learning nuggets promote an environment where continuous learning and growth are valued

7. Improves Employee Engagement and Retention

Investing in employee development shows an organization’s commitment to its staff. This can boost engagement and motivation, reduce turnover, and increase loyalty.

8. Identifies Knowledge Gaps

When you include regular assessments and follow up with quizzes or scenarios to test understanding, you get valuable insights into areas that need improvement. These assessments work like a diagnostic tool, helping to identify specific skill gaps and guide future training plans.

9. Enhances Team Collaboration

Regular training ensures all team members have a shared understanding and knowledge base, which can improve team dynamics and collaboration.
