A learning technique that spaces out review sessions at increasing intervals, leveraging the brain's natural memory consolidation process to dramatically improve long-term retention.
Spaced repetition is based on the "spacing effect" discovered by psychologist Hermann Ebbinghaus — the finding that information is better remembered when review sessions are spread out over time rather than crammed into a single session. Modern spaced repetition systems use algorithms to determine the optimal moment to resurface each piece of information, just as the learner is about to forget it. In workplace training, this means employees retain compliance requirements, product knowledge, and procedures far longer than with traditional one-and-done training. AI-powered platforms can automate the scheduling and adapt to each individual's learning pace.
