In-house or public training: which is right for your team

When you decide to develop your people, one of the first practical choices is format. Do you send a few staff to a public course open to other organisations, or do you bring a trainer in to run a session built around your team? Both work well in the right situation. The trick is matching the format to your actual need.

When public courses make sense

Public courses shine when you have a small number of people who need a widely understood skill. If two staff members need a grounding in project management or financial reporting, sending them to a scheduled course is usually simpler and cheaper than arranging a private session.

There is a second benefit that is easy to overlook. In a public room, your people sit alongside peers from other companies and hear how those organisations handle the same challenges. That exposure can be as valuable as the content itself, especially for staff who rarely step outside their own environment.

When in-house training is the better fit

Once you have a group of roughly six or more people who all need the same skill, in-house training often becomes the more sensible option on cost alone. You pay for the session rather than per seat, and travel time disappears.

In-house also lets you shape the content. A trainer can use your own documents, your own systems, and examples drawn from your industry. When the material needs to reflect your policies, your customers, or sensitive internal information, a private session is usually the only responsible choice.

Weigh the numbers, then the outcome

Start with a simple sum. Multiply the public course fee by the number of people, then compare that against the cost of a private session plus any venue or travel. The headcount where in-house becomes cheaper varies, so run the figures for your specific case rather than assuming.

Then look past the money to the result you want. If you need consistency, so that everyone applies the same method the same way, in-house delivery builds that shared standard in a single room. If you value fresh outside perspective more, a public course delivers it.

A practical way to decide

For small numbers, general topics, or one-off needs, lean towards public courses. For larger groups, company-specific content, or skills you want applied uniformly, lean towards in-house. Many organisations end up using both across a year, and there is nothing wrong with that. Choose per need rather than settling on one format for everything.
