The process for developing the Next Generation Science Standards (NGSS) was not a simple one. There were many decisions made that while necessary did not make the process simpler. However, one decision was never in debate—the NGSS were meant for all students and to achieve this, the development had to have all students in mind from the beginning. It is time for “All Standards, All Students.” Teacher background information, standards, assessments, and references are provided. This book selection also includes the Table of Contents, About the Editors, Contributors, Preface, and Index.
