What Is the Operating Engineers Certification Program?
The Operating Engineers Certification Program (OECP) is a credentialing program that assesses and certifies heavy equipment and crane operators. It was developed by the International Union of Operating Engineers (IUOE) in partnership with testing experts and industry stakeholders to ensure that certified professionals meet the highest levels of competence.
The OECP is designed to:
Improve jobsite safety
Standardize skills verification
Meet or exceed Occupational Safety and Health Administration (OSHA) requirements
Ensure regulatory compliance with ANSI/ASME B30 safety codes
Certification categories under OECP include:
Lattice Boom Cranes
Telescopic Boom Cranes
Tower Cranes
Articulating Cranes
Rigging and Signalperson Certifications
OECP is recognized by many employers, government agencies, and project owners as a preferred or mandatory qualification for heavy equipment operators.
How to Become Certified Under OECP
Becoming OECP-certified involves a structured process that includes formal instruction, practical training, and successful completion of both written and hands-on exams. The process is tailored for aspiring crane operators, apprentices, and existing professionals seeking certification renewal or additional endorsements.
Steps to Certification:
Step 1: Join a Training Program or Apprenticeship
Many OECP candidates begin through IUOE-affiliated apprenticeship programs, which offer comprehensive training in crane operation, safety procedures, and equipment maintenance. These programs often span 3–4 years and include paid on-the-job training.Step 2: Prepare for the Certification Exams
Candidates are expected to study OECP-specific materials and OSHA/ANSI regulations. Training includes classroom instruction on:Crane components and inspection
Load charts and capacity
Signaling and rigging
Operational safety
Emergency procedures
Step 3: Take the OECP Exams
The certification includes:Written Exam: Multiple-choice questions assessing technical knowledge and safety understanding
Practical Exam: Hands-on evaluation involving crane setup, operations, load management, and deconstruction
Step 4: Maintain Certification
OECP credentials are valid for five years. Recertification requires passing updated exams and, in some cases, demonstrating continued employment or retraining.
