ISA CCST Level II study guide
ISA CCST Level II · Work through your exam, one topic at a time.
The ISA Certified Control Systems Technician (CCST) Specialist - Level 2 is the middle of three CCST certification levels offered by the International Society of Automation for control systems technicians. ISA describes Level 2 as demonstrating Level 1 knowledge plus some knowledge of administration, supervision or management, and it carries a seven-year minimum education and experience requirement. The ISA CCST Level II study guide has 5 sections and about 1,830 words.
01Calibration
The Calibration domain tests whether you can run a defensible calibration: choose a traceable standard, compute error against tolerance, record as-found and as-left data, and decide what to do when a device fails. Level II expects you to know the difference between calibrating an instrument and calibrating a loop, and to understand smart-transmitter adjustments.
404 words, about 2 min02Maintenance, Repair and Troubleshooting
This domain tests systematic fault finding on instrumentation and control loops, plus safe repair practice. Level II questions often present a symptom and ask for the next diagnostic step, so you must be able to divide a loop into field, wiring, I/O, controller and HMI sections and test each in a logical order.
384 words, about 2 min03Project Start-up, Commissioning and Loop Checking
This domain covers the transition from construction to operation: pre-commissioning, commissioning, loop checks and start-up. Level II tests whether you can prove that a loop is correct from field device to HMI, that alarms and fail-safe actions work, and that every check is documented and signed off.
366 words, about 2 min04Project Organization, Planning and Documentation
This domain tests how instrumentation work is organized and documented: the instrument index, I/O list, loop drawings, cable and termination schedules, calibration records and turnover packages. Level II expects you to know which document controls which piece of information and how revision control prevents field errors.
338 words, about 2 min05Administration, Supervision and Management
This domain tests the supervisory side of instrumentation work: assigning qualified technicians, controlling calibration intervals, reviewing records, managing safety and contractors, and making defensible decisions when production pressure conflicts with maintenance requirements. Level II expects practical judgment, not general management theory.
