How is the PECB ISA/IEC 62443 Lead Implementer exam structured?
The exam is multiple choice, lasts three hours, and requires 70% to pass. It covers two domains: the fundamental principles and concepts of industrial automation and control systems, and applying the ISA/IEC 62443 standards for availability, resilience, and critical infrastructure protection.
The PECB ISA/IEC 62443 Lead Implementer exam is multiple choice, lasts three hours, and requires a minimum score of 70%. It covers two competency domains: the first verifies command of the fundamental principles and concepts of industrial automation and control systems (IACS); the second assesses the application of the ISA/IEC 62443 standards for operational availability, resilience, and the protection of critical infrastructure.
It is delivered online through the PECB portal and leads to a professional certification valid for three years, subject to annual maintenance. The Abilene Academy trainers are fluent in English, French, and Spanish, and can support exam-specific preparation across the four training days.
Because the second domain is application-focused, candidates should expect scenario questions that ask them to select an appropriate control for a given operational context rather than to recall a definition. Practising with realistic IACS scenarios during the course closes this gap.

Expert Insight
The questions candidates fail most often are those that require choosing between two valid controls based on operational context. Practising with real scenarios in class closes this gap.
“The exam assesses applied judgement, not clause memorisation.”
