Principle
Prefer learning that produces work-like evidence
Completion is evidence of participation, not automatically of capability.
When it fits
- Training creates certificates but little proof that the skill works under realistic constraints.
When to avoid it
- Simulations cannot prove full workplace competence, and some skills legitimately require formal accredited training.
Why it matters
When practical, choose learning that ends in a realistic output: analysis, design, explanation, code, facilitation, case solution or supervised performance. Add a check or external review. Keep credentials when they are required or useful, but pair them with evidence of application.
An example
A security course is followed by a threat-model exercise on a public sample system rather than only a completion badge.
Check your result
The learning produces an artifact or performance you can evaluate against a target task.
Keep this limit in mind
