Inspector Certification Program

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. 

For ADA Curb Ramp Certification details and class materials links, scroll down to the Course Registration & Information Links section at the bottom of this page.

PLEASE NOTE: We are now offering inspector certification challenge exams at the Salem Materials Lab. There are limited slots available. See Challenge Exams below for more details and a registration form.

Challenge Exams

In light of the Governor's COVID-19 directive,
we are providing limited Challenge exams for the Portland
and Salem area at the Salem Materials Lab.
Each date may have up to 7 attendees.
Open dates are listed on the registration form.

​To register to challenge an exam, complete the Challenge Exam Registration Form. The form includes the challenge exam schedule. You may challenge any inspector exam (except for Traffic Control Supervisor and ADA). You may challenge an exam in lieu of taking a class. If you do not pass a challenge exam, you must take the training course before taking another exam.
In addition, you may take a challenge exam if you have already failed your first exam from the training course. You are allowed to take a second exam by challenging the exam.
If someone fails an exam twice, there are options to take the exam a third time. For detailed information regarding the testing process refer to the Inspection and Certification Program document.
To challenge an exam, you are responsible to supply all the required materials. The Resource Manual, Plans and Special Provisions for the General exam are provided for you at the testing location. The required materials are listed on each certification's information page. Links to those pages are provided below under Course Information & Registration Links.

​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.

Due to the COVID-19 Pandemic, it has been determined that we will not conduct in-person Construction inspection training, workshops, or forums in the 2020-2021 season. Some virtual and/or online sessions will be offered. We will provide details as they become available. Construction material technician training will continue with cooperation with our Industry Partners. For information, visit APAO and OCAPA’s websites for current enrollment details.

Options for inspector certifications are being researched and developed. Our primary goal is to craft a training plan and implement it by January 1, 2021. This will include a process for new and currently certified inspectors to obtain a 1-year certification. An additional goal is to create challenge exam events to extend certifications for the fully allotted time designated for each specific discipline. We will update the challenge events calendar after January 1, 2021.

If you would like direct communication regarding any of the Construction training courses, workshops, and/or forums, please complete the Interest Form. Send it by email using the button in the upper right hand corner of the form, or email it directly to our construction training mailbox.

Thank you for your patience as we work out these details.
