This meta-analysis examines whether low-stakes practice tests improve later learning compared with non-testing activities such as restudying.
Across 118 experiments and 272 independent effects, practice testing produced a robust overall benefit. The size of the benefit varied with features such as test format, the relationship between practice and final tests, and the number of retrieval opportunities. Benefits appeared with and without feedback, although feedback remains educationally important because it corrects errors. The authors distinguish retrieval practice from high-stakes accountability testing: the learning mechanism is the act of bringing information to mind.
For educators, the review supports frequent, low-stakes opportunities to retrieve knowledge and suggests varying formats while keeping retrieval aligned with later learning demands.
