A review of the literature on staff training strategies that minimize trainer involvement

Marano and colleagues looked at 54 studies on staff training. They wanted to know which methods let people learn job skills without a trainer standing there.

The team pulled every paper that used video models, online lessons, or self-check packets. Settings ranged from group homes to clinics.

Across all 54 studies, staff reached mastery when they learned on their own time. Short videos, click-through tutorials, and printed checklists all worked.

Trainer time dropped because people could watch, practice, and test themselves without live feedback.

Arnal Wishnowski et al. (2018) showed the same thing earlier. Their online manual plus short clips taught staff and students to run MSWO preference tests with no in-person coach.

Kennedy et al. (2024) went one step further. They found tablet lessons beat live instructors on speed and accuracy, backing the review’s claim that tech can out-perform people.

Aquino et al. (2024) seems to disagree. College students liked interactive computer lessons yet scored no higher on tests. The gap is about the skill target: Aquino taught concepts, while Marano’s pool taught hands-on procedures. Concepts need more than clicking through slides.

Wallisch et al. (2024) extends the idea to parents. Moms and dads who felt unsure used extra asynchronous videos and improved the most, showing the model works beyond paid staff.

You can stop blocking off hours to shadow every new hire. Pick a short video or online module that shows the exact task, add a brief practice sheet, and let staff certify themselves. Start tomorrow by replacing one live orientation with a five-minute clip plus a short quiz. You save time, and the data say your team will still hit mastery.
