installs, configures and maintains audiovisual solutions
coordinates, communicates and documents ongoing installation responsibilities and activities
performs system tests, conducts training and provides project closeout documentation
The CTS program is accredited under ANAB / ISO/IEC 17024:2012, the international standard for personnel certification. CTS-I questions are job-task based, testing how you apply your knowledge in real installation scenarios rather than how well you remember facts.
