The Electronic Systems Professional Alliance (ESPA) was founded by CEDIA, CTA and NSCA and existed from 2006-2022. ESPA provided training materials to education partners, coordinated workforce development activities, and oversaw the Electronic Systems Technician (EST) certification which certified over 3,000 individuals. Electronic Systems Technicians install and service low-voltage electronic systems in residential and commercial environments. This includes systems such as audio, video, lighting, control, security and telecommunications.
