Inspector Certification Program

The Inspector Certification Program is part of the Oregon Department of Transportation's effort to ensure quality control and quality assurance for the construction of transportation facilities.

An image of the phrase ODOT Materials & Inspection and the letters Q and AThis program provides training and resources for construction inspectors, and ensures consistent administration of highway construction projects. Inspection and monitoring of construction activities by certified instructors safeguards compliance with contract documents and workmanship on ODOT construction projects.

The Inspection Certification Program document outlines the certification program elements and intent.

Full time inspectors are required to pass the General Inspector Certification exam and required discipline certifications, as needed. Some aspects of the program are tailored for convenience, such as not requiring a certified inspector to hold a Bridge Inspection Certification until he or she is expected to inspect bridge construction.

Training is available for each of the certifications; however, an Inspector may choose to challenge the exam. Training courses are scheduled between November 1 and April 30. Class schedules and registration information are provided below.

​The Inspection Quality Assurance Program is dedicated to providing construction inspector training to:

  • Ensure consistent construction inspection administration through education on contract document resources;
  • Define the role and responsibilities of the Inspector concerning construction workmanship, materials and testing;
  • Demonstrate effective documentation to reduce construction claims and contract disagreements; and
  • Promote industry best practices to ensure quality methods and materials are used on ODOT projects.


To apply for the certification, you may either register for the one of the training courses, where an exam will be administered, or submit an application to challenge the exam. The challenge applications are processed through the Construction Section. There are no fees for taking the challenge exam. Appropriate fees will be charged for hard copies of the training manuals. Copies of the training manuals are available electronically on our Publications page.

Inspector Certifications will be valid for a 3-5 year period, depending on the certification, after which you must take and pass the exam to maintain the Certification for an additional 3-5 years.

If you are new to construction, it may benefit you to go through the first module of the Transportation Curriculum Coordination Council Plan Reading Series prior to the Certified General Inspector Training. This can help familiarize yourself with the basics of plan reading. Also, if it has been a while since your last math class, the Transportation Curriculum Coordination Council Math Module is useful as background for all of the certification classes. As an alternative, a [Basic Highway Math] document is available.

Other courses from the Oregon Department of Transportation and the Oregon Department of Administrative Services may found on iLearn.
