As continual learning systems advance, developers face the challenge of preserving prior knowledge while absorbing new information. A well-structured curriculum acts as a compass, guiding learning phases to balance retention and adaptability. By sequencing tasks, managing memory, and incorporating regularization strategically, models can flatter stability without sacrificing plasticity. The result is a robust framework that grows with experience rather than eroding what was once learned. This article explores practical design principles, actionable steps, and evaluative metrics that help prevent catastrophic forgetting across diverse domains and data streams. Readers will gain a blueprint for durable continual learning campaigns.
