Inspector Certification Program

Please see our Construction Training and Certification 2023-2024 schedule for the latest information about our current offerings. Remember, if you are an external learner to ODOT, you need to set up your new Workday Learning account before you may enroll in our courses.

This 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 AWe provide training and resources for construction inspectors to ensure consistent administration of highway construction projects. Certified instructors safeguard 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. The program is tailored for convenience. For instance, you do not have to have a Bridge Inspection Certification until you are expected to inspect bridge construction.

Training is available for each of the certifications. However, you may choose to challenge an exam.
