Book excerpt: Competency-Based Education introduces educators to a new model for anytime, anywhere schooling and provides tools and curriculum resources for redesigning the traditional structures of K–12 schools. Based on pioneering work across multiple states, the book shows how educators can design central elements of competency-based education—including performance tasks, personal learning plans, and grading systems—to meet the needs and interests of all students. Rose L. Colby provides critical tools for creating these elements in collaborative teams and engaging stakeholders such as educators, parents, and community members. The book incorporates case studies and voices from the field, and examines the variety of competency models that schools have adopted, highlighting the benefits for students. Competency-Based Education provides a much-needed resource at a time when states, districts, and schools are working to implement competency-based models and experimenting with new accountability systems that include evidence of learning beyond standardized tests.
