The Technology Student Association (TSA) is a national, non-profit career and technical student organization (CTSO) of middle school and high school students who are engaged in STEM (science, technology, engineering, and mathematics). Since TSA was chartered in 1978, over 5,000,000 student members have participated through competitions, intracurricular activities, leadership opportunities, community service, and more.

TSA provides rules and guidelines for more than 70 middle school competitions and high school competitions for use in a traditional classroom and virtually for distance learning. All TSA competitions are aligned with STEM standards, 21st century leadership skills, and the U.S. Department of Education's National Career Clusters Framework®. TSA middle and high school competitions are categorized by career pathways in Architecture and Construction Technology, Communications Technology, Computer Science and Information Technology, Leadership, Manufacturing and Transportation Technology, STEM (General), STEM and the Arts, and Technology and Research. 

TEAMS is a STEM competition providing students in middle school and high school the opportunity to discover engineering. Students work together in teams and use practical applications of math and science to answer engineering questions about every day, real-world challenges.

TSA VEX Robotics is an engaging robotics competition in which students further their knowledge and skills in STEM areas. This competition is a collaborative effort of TSA and the Robotics Education and Competition Foundation (REC Foundation).
