[Test of knowledge and skills enhances learning].

Test-enhanced learning is an evidence-based pedagogical tool for enhancing retention of both knowledge and skills. The phenomenon is independent of external factors such as feedback and intention to learn. The mechanism is complex and possibly related to stress and gender. Tests immediately after learning are most effective - and formats that support test-enhanced learning most effectively involve composing an answer or actively performing a skill. Use of tests in education should be integrated in the curriculum ensuring that the tests relevantly complement and enhance learning of knowledge or skills.
