ISO Programs Overview

The International Organization for Standardization (ISO) is a worldwide federation of national standards bodies from more than 145 countries, one from each country. ISO is a non-governmental organization established in 1947 and based in Geneva, Switzerland. Its mission is to promote the development of standardization and related activities in the world with a view to facilitating the international exchange of goods and services, and to developing cooperation in the spheres of intellectual, scientific, technological and economic activity. ISO's work results in international agreements which are published as International Standards and other types of ISO documents

ANSI is the sole U.S. representative and dues-paying member of the International Organization for Standardization (ISO), and as a founding member of the ISO, ANSI plays an active role in its governance.

ISO Organizational Structure

The primary governance groups of ISO are:

  • The ISO General Assembly, which is the annual meeting of all ISO members, and its agenda typically includes actions relating to the review of the ISO annual report, approval of ISO’s multi-year strategic plan, and ISO’s finances.
  • The ISO Council, which meets twice a year and is responsible for the development of ISO’s multi-year strategic plan, the development of the ISO annual budget, ISO’s relations with other external organizations, and other political/strategic decisions and the general operations of ISO. The ISO Council consists of the principal officers of ISO and eighteen elected member bodies, including ANSI for the USA. ANSI is one of five permanent members to the ISO Council.
  • The ISO Technical Management Board (ISO/TMB),which meets three times each year and reports to and advises the ISO Council on all matters concerning the organization, coordination, strategic planning, and programming of the technical work of ISO. The ISO/TMB consists of the ISO Vice President for Technical Management and twelve elected member bodies, including ANSI for the USA. ANSI is one of four permanent members of the ISO TMB.
  • ISO Technical Committees and Subcommittees. ISO standards are developed by technical committees comprising experts from the industrial, technical and business sectors which have asked for the standards, and which subsequently put them to use. These experts may be joined by others with relevant knowledge, such as representatives of government agencies, testing laboratories, consumer associations, environmentalists, academic circles and so on. The experts participate as national delegations, chosen by the ISO national member institute for the country concerned. These delegations are required to represent not just the views of the organizations in which their participating experts work, but of other stakeholders too. According to ISO rules, the member institute is expected to take account of the views of the range of parties interested in the standard under development and to present a consolidated, national consensus position to the technical committee.

Through the American National Standards Institute, the USA has immediate access to the ISO standards development processes. ANSI participates in almost the entire technical program of the ISO (nearly 80%), and administers many key committees and subgroups (nearly 20% of all ISO TCs and SCs).

Part of ANSI’s responsibilities as the U.S. member body to the ISO includes accrediting U.S. Technical Advisory Groups (U.S. TAGs). The primary purpose of these TAGs is to develop and transmit, via ANSI, U.S. positions on activities and ballots of the international technical Committee.


To ensure a strong and effective U.S. voice in international standardization, ANSI’s ISO Team (ISOT) acts as the interface between ANSI-accredited U.S. Technical Advisory Groups (U.S. TAGs) and/or ANSI-delegated U.S. held ISO secretariats.

ISOT daily operations include monitoring and recording of ISO documents, processing votes on behalf of U.S. TAGs, accrediting delegates to attend international meetings, nominating experts to participate on working groups, coordination with key group such as the ANSI ISO Forum (AIF), ANSI ISO Council (AIC), and the ISO Technical Management Board (TMB), administering ANSI Virtual Technical Advisory Groups (VTAGs), facilitating training programs, among many other functions. In addition to daily responsibilities, ISOT is available to assist with any committee specific issues U.S. TAGs or U.S. held secretariats may be facing. ISOT staff is well versed in the ISO procedures, ANSI International Procedures, and has experience in all aspects of the ISO process. Visit the ISOT Resource Page for additional information

For organizations that are new to ISO or want additional support with ISO related activities, ANSI’s ISOT staff provides hands-on, practical guidance on all aspects of administration of U.S. TAGs or ISO Secretariats through its fee-based Enhanced Services program. For more information, contact
