IIQIE is the sole EOQ Competence Center Agent in Israel




Certification from IIQIE is considered a mark of quality excellence in many industries. Becoming certified as Reliability Engineer confirms your commitment to Reliability and the positive impact it will have on your organization.


Each certification candidate is required to pass a written examination that consists of multiple-choice questions that measure comprehension of the body of knowledge.

The iICRE examination is a two-parts, 120-questions, four-hour exam and is offered in English/Hebrew. 

Certified Reliability Engineer

The Israeli International Certified Reliability Engineer (IICRE) understands the principles of performance evaluation and prediction to improve product/systems safety, reliability, and maintainability. This body of knowledge and applied technologies include, but are not limited to, design review and control; prediction, estimation, and apportionment methodology; failure mode and effects analysis; the planning, operation, and analysis of reliability testing and field failures, including mathematical modeling; understanding human factors in reliability; and the ability to develop and administer reliability information systems for failure analysis, design, and performance improvement and reliability program management over the entire product life cycle.

Work Experience 

You must have eight years of on-the-job experience in one or more of the areas of the Certified Reliability Engineer Body of Knowledge. A minimum of three years of this experience must be in a decision-making position. “Decision making” is defined as the authority to define, execute, or control projects/ processes and to be responsible for the outcome. This may or may not include management or supervisory positions.

If you are now or were previously certified by as a Quality Engineer, Quality Auditor, Software Quality Engineer, Supplier Quality Professional, or Manager of Quality/ Organizational Excellence, experience used to qualify for certification in these fields often applies to certification as a Reliability Engineer.

If you have completed a degree from a college, university, or technical school with accreditation accepted by IIQIE, part of the eight-year experience requirement will be waived as follows (only one of these waivers may be claimed):

• Diploma from a technical or trade school— one year waived

• Associate’s degree  —  two years waived

• Bachelor’s degree   —  four years waived

• Master’s or doctorate —  five years waived
