TIA's Standards division convenes communities of interest around nine engineering committees and is the administrator for a number of U.S. Technical Advisory Groups. These communities conduct the writing and maintenance of voluntary, industry-driven, consensus-based standards and specifications for the ICT industry.

More than 1,000 individuals - representing network equipment manufacturers, service providers, government entities, and end users - currently serve on TIA's Engineering Committees. Government agencies are allowed to participate at no cost as "non-voting" observers to TIA's standards engineering committees. TIA also maintains reciprocal agreements with other Standards Developing Organizations (SDOs) and academic institutions.
