ISA’s CyberU online instructor-led training course offers the benefit of a high-quality ISA training course with the added advantage of studying at your own pace in the office, at home or while traveling.

This online course utilizes online training modules, additional text materials, online evaluations, and email discussions. Students will have access via email to an instructor and have an opportunity to participate in live Q&A sessions with the instructor and other class participants. The course focuses on the engineering requirements for the specification, design, analysis, and justification of safety instrumented systems for the process industries. Students will learn how to determine safety integrity levels and evaluate whether proposed or existing systems meet the performance requirements.


This CyberU course runs for seven (7) weeks. You will have access to seven online modules for a web/audio session. Each module takes approximately 60 minutes. Your course syllabus will guide you through the course modules, provide assignments, and the schedule for live Q & A sessions.


Certificate Program (if available) A Certificate of Completion indicating the total number of CEUs earned will be provided upon successful completion of the course. Your course registration includes your registration for the exam.
