Professional Mathematical Sciences organizations

In addition to the MAA, there are a variety of special professional mathematical sciences organizations:

The American Mathematical Association of Two-Year Colleges (AMATYC) is the only organization exclusively devoted to providing a national forum for the improvement of the instruction of the mathematics in the first two years of college.

The American Mathematical Society (AMS), through its programs and services, aims to promote mathematical research and its uses, strengthen mathematical education, and foster awareness and appreciation of mathematics and its connections to other disciplines and to everyday life.

The American Statistical Association (ASA) is a scientific and educational society founded to promote excellence in the application of statistical science.

The Association for Computing Machinery (ACM) is a professional organization whose main goal is advancing the skills of information technology professionals and students worldwide.

The Association for Women in Mathematics (AWM) is dedicated to encouraging women and girls in the mathematical sciences.

The Computing Research Organization (CRA) is an organization of academic departments of computer science and related fields whose mission is to strengthen research and education in computing, to expand opportunities for women and minorities, and to improve public understanding of the importance of computing.

The Institute for Operations Research and the Management Sciences (INFORMS) is a professional organization that helps practitioners apply scientific tools and methods to improve systems and operations and to assist in managerial decision making.

The National Association of Mathematians (NAM) promotes excellence in the mathematical sciences and the mathematical development of underrepresented minorities.

The National Council of Teachers of Mathematics (NCTM) serves the needs of mathematics teachers at all levels from elementary school teachers through college professors.

The Society for Industrial and Applied Mathematics (SIAM) promotes the development of the mathematical methods needed in a variety of applications areas.

The Society of Actuaries (SOA) has as its mission, to advance actuarial knowledge and to enhance the ability of actuaries to provide expert advice and relevant solutions for financial, business, and societal problems involving uncertain future events.
