Protocol
Use a representative task before designing the drill
A tidy drill can train the wrong game.
When it fits
- When practice is easy to score but may not resemble the performance you actually need.
When to avoid it
- Representative practice does not mean copying confidential or dangerous real cases. Use sanitized or simulated cases when safety, privacy or authority require it.
Why it matters
Start with the target performance: the decisions, outputs, constraints and cues that matter. Then create drills that preserve the part of that structure you are trying to improve. A drill may simplify the task, but it should have an explicit path back to representative performance.
Steps
- Target output is named.
- Important decision cues are preserved.
- The drill trains a component that appears in the target task.
- A whole-task retest is scheduled.
- Success on the drill is not treated as complete competence.
An example
Typing flashcards about incident-management terms is not enough if the real job is deciding what to check first under incomplete evidence.
Check your result
The learner can explain which real performance requirement each drill trains and how it will be tested later.
Keep this limit in mind
- Representative practice does not mean copying confidential or dangerous real cases. Use sanitized or simulated cases when safety, privacy or authority require it.

Evidence and sources
A meta-analysis found deliberate practice explained meaningful but limited variance in performance, with much smaller shares in education and professions than in games, music and sports.
The result argues against an hours-only expertise claim; it does not show that structured practice is useless.
A meta-analysis of adaptive training found that effects varied by instructional intervention, with adaptive difficulty showing the strongest results among the examined categories.
The literature was heterogeneous and much of the context was military training; this does not validate every adaptive-learning product.
