ISA and the Automation Standards Compliance Institute (ASCI) worked with industry experts who are active on the ISA/IEC 61511 standard committee to develop three certificate exams that are designed to increase knowledge and awareness of the ISA/IEC 61511 standards. Compliance with the standard requires a focused and continuous approach to functional safety. The standard is a performance-based standard, so there is a need for competent and qualified people to develop and monitor the application of the standard to a facility or process. View the comparison chart here to learn how ISA/IEC 61511 Safety Instrumented Systems Certificate Program compare to other safety programs. The ISA/IEC 61511 specialist certificates are awarded to those who successfully complete a designated training program, any prerequisites (for Certificates 2 and 3), and pass a multiple-choice exam. 

There are no required prerequisites or applications for this program; however, it is highly recommended that applicants are familiar with the ISA/IEC 61511 standards.
