Knowledge Retention
The ability to preserve and recall learned information over time, a critical metric for measuring training effectiveness.
Knowledge retention refers to how well learners remember and can apply what they've learned over time. Research shows that without reinforcement, people forget up to 70% of new information within 24 hours (the Ebbinghaus forgetting curve). Effective L&D strategies combat this through techniques like spaced repetition, active recall, practical application, and microlearning. Measuring retention through assessments, on-the-job performance metrics, and periodic knowledge checks helps organizations understand true training ROI.
