The historical context for the development of the Learner-Centered Psychological Principles (LCPs) is summarized. This context includes a discussion of why the LCPs and their practices are particularly important in the current educational reform era. Implications for practice are provided, and the article concludes with how the LCPs can contribute to a national framework for the systemic redesign of K-20 education. The learner-centered framework provides validation for practices that achieve a balanced focus on both learning and learners. Research-validated principles establish a foundation for clarifying components of a positive learning environment at classroom and school levels that can increase the likelihood of more students experiencing success.
