TRENDS AND ISSUES LEADING TO STANDARDS-BASED REFORM
Twenty-five years ago NCTM released Curriculum and Evaluation Standards for Teaching Mathematics, which presented a comprehensive vision for mathematics teaching, learning, and assessment in grades K—12. Other significant publications, including Principles and Standards for School Mathematics and the Common Core State Standards for Mathematics continue to identify what we believe students should know and be able to do throughout their school mathematics experience.

In the preceding quote from Linda Gojak’s NCTM 2014 final President’s Message (2014), she summarizes the major Standards-based documents that seek to guide teaching and learning for the 21st century. To better understand the shifts required for their implementation, a brief background on the major theories and documents that underlie these documents, which I will call Standards- based, are provided next.
