The following organizations have established the Mathematics Common Core Coalition, MC3:


The National Council of Teachers of Mathematics (NCTM) is a public voice of mathematics education, providing vision, leadership, and professional development to support teachers in ensuring mathematics learning of the highest quality for all students. Founded in 1920, NCTM is the world’s largest mathematics education organization, with more than 90,000 members and 230 Affiliates throughout the United States and Canada.


The National Council of Supervisors of Mathematics (NCSM) is a mathematics leadership organization for educational leaders that provides professional learning opportunities necessary to support and sustain improved student achievement. NCSM envisions a professional and diverse learning community of educational leaders that ensures every student in every classroom has access to effective mathematics teachers, relevant curricula, culturally responsive pedagogy, and current technology.

Association of Mathematics Teacher Educators

The Association of Mathematics Teacher Educators (AMTE) and its 1000 members work together to promote and improve the education of preservice and inservice teachers of mathematics. AMTE members include teacher educators in schools and colleges of education and departments of mathematics as well as others interested in mathematics teacher education and professional development. The organization is an active member of the Conference Board of the Mathematical Sciences (CBMS) (along with NCSM, NCTM, TODOS, Benjamin Banneker Association and others). AMTE is celebrating its 20th anniversary and has 20 active state or regional affiliate groups. Marilyn Strutchens, M.C. Fraley Distinguished Professor of Mathematics Education, Auburn University is the president of the organization, and Nadine Bezuk, Qualcomm Professor of Mathematics Education School of Teacher Education, San Diego State University is the executive director. See the AMTE website ( for a list of the Board of Directors and other information.

Association of State Supervisors of Mathematics

The Association of State Supervisors of Mathematics (ASSM) is an organization whose members provide supervising and/or consulting services in the area of mathematics as a staff member of the education agency of any state in the United States of America, the District of Columbia, possessions of the United States of America, territory of the United States, US Department of Defense, Canadian Province, or Bermuda. ASSM is unique as it is the only professional mathematics organization whose membership is entirely composed of current or previous state or provincial supervisors of mathematics. The organization not only serves as a network for state or provincial supervisors of mathematics but our members are leaders in state and national efforts to improve mathematics education. 

Council of Chief State School Officers

The Council of Chief State School Officers (CCSSO) is a nonpartisan, nationwide, nonprofit organization of public officials who head departments of elementary and secondary education in the states, the District of Columbia, the Department of Defense Education Activity, and five U.S. extra-state jurisdictions. CCSSO provides leadership, advocacy, and technical assistance on major educational issues. The Council seeks member consensus on major educational issues and expresses their views to civic and professional organizations, federal agencies, Congress, and the public.

National Governors Association

The National Governors Association (NGA) is the collective voice of the nation's governors and one of Washington, D.C.'s most respected public policy organizations.

NGA also provides management and technical assistance to both new and incumbent governors.

Smarter Balanced Assessment Consortium

The SMARTER Balanced Assessment Consortium (SBAC) is a state-led consortium working to develop next-generation assessments that are aligned to the Common Core State Standards and that accurately measure student progress toward college and career readiness. The work of the Consortium is guided by the belief that a high-quality assessment system can provide resources and tools for teachers and schools to improve instruction and help students succeed. The Consortium involves educators, researchers, policymakers, and community groups in a transparent and consensus-driven process.

Partnership for Assessment of Readiness for College and Careers

The Partnership for Assessment of Readiness for College and Careers (PARCC) is a consortium of 24 states working together to develop a common set of K-12 assessments in English and math anchored in what it takes to be ready for college and careers. These new K-12 assessments will build a pathway to college and career readiness by the end of high school, mark students’ progress toward this goal from 3rd grade up, and provide teachers with timely information to inform instruction and provide student support.
