Why training does not stick, and what actually makes skill last

The research on transfer of training, from Baldwin and Ford in 1988 through the reviews since, is consistent. What decides whether training turns into changed behavior is not the classroom, it is the work environment: the chance to apply the skill on real tasks and the reinforcement that follows. Skill practised only in a workshop tends to fade.

Two of the sturdiest findings in cognitive science back this up. The spacing effect, revisiting material over days rather than cramming, produces far better retention, confirmed across hundreds of experiments. And retrieval practice, actively recalling rather than re-reading, builds durable memory. The forgetting curve is steep, and spacing plus recall is what flattens it.

Most learning fails in a predictable way: taught once, never practised, quietly forgotten. The fix is not a better course, it is a different shape. Short repeated practice on the actual work, spread over time, with feedback. That is a systems problem, not a content problem.

Judge any training by whether it changes Monday's work, not by whether the session felt good.

Space practice over weeks. One session, however good, loses to five small ones.

Recall beats review. Doing the task from memory teaches more than watching it again.

Attach every new method to a real task the same week, or expect it to vanish.

Build a light spaced schedule: revisit a skill after a day, a few days, a week, a couple of weeks.

End each practice by naming what held and what slipped. Feedback is the reinforcement the research demands.

Do not cite the popular 'only 10 percent of training transfers' figure. It is an unfounded rhetorical claim with no evidence behind it. The mechanism is real; that number is not.

Spacing feels slower and less satisfying than cramming. The feeling is wrong; the retention is better.
