The "Core Knowledge" movement is an educational reform based on the premise that a grade-by-grade core of common learning is necessary to ensure a sound and fair elementary education.
The movement was started by Dr. E. D. Hirsch, Jr., author of The Schools We Need, and is based on a large body of research in cognitive psychology, as well as a careful examination of several of the world's fairest and most effective school systems.
Dr. Hirsch has argued that, for the sake of academic excellence, greater fairness, and higher literacy, early schooling should provide a solid, specific, shared core curriculum in order to help children establish strong foundations of knowledge. After wide consultation, the content of this core curriculum has been outlined in two books -- the Core Knowledge Preschool Sequence and the Core Knowledge Sequence, K-8-- that state explicitly what students should learn at each grade level. Currently, hundreds of schools and thousands of dedicated educators are participating in this school reform movement throughout the United States.
