Which standards does the control systems PE exam supply?

Along with the PE Control Systems Reference Handbook, you get standards such as ANSI/ISA-5.1 (2024) on instrumentation symbols and ANSI/ISA/IEC 61511 (2018) on safety instrumented systems. The specifications list them all, with editions.

Booking a once-a-year exam

With one date a year, a missed appointment means waiting for next year’s exam. To switch to another exam, you cancel and register again, and NCEES keeps $50 of the fee.
