The Core Knowledge Approach
The Core Knowledge approach puts knowledge at the heart of schooling.
Specific and Sequenced: Most curriculum standards provide general goals and objectives but offer teachers little guidance about the specific knowledge students should learn in each grade. In contrast, the Core Knowledge approach is to specify, in a clear grade-by-grade sequence, what students need to know.
Excellence and Equity: Only by specifying the knowledge and skills that all children should share can we guarantee equal access to that knowledge. Educational excellence and equity require that every child in a democracy have access to important shared knowledge and language.
Starting Early: It’s important to begin building strong foundations of knowledge in the early years. The Core Knowledge approach focuses on preschool through grade eight. In these early years, especially the preschool and elementary grades, schools can do the most to help children lay the groundwork for language development and future success.
