How is the CST Associate Recognition different from the Certified Control Systems Technician (CCST) program?
CST Associate Recognition is not a certification. Those who take the CST Associate examination may be interested in pursuing the ISA credential, Certified Control Systems Technician® (CCST®) once the education and/or experience level reaches five years. Achieving CST Associate Recognition equals a maximum of one year towards the CCST® requirements. For more information on the CCST® program, click here.
