Local government and tribal transportation practitioners across the U.S. are responsible for more than 75 percent of our Nation’s highway network. AASHTO’s TC3 training library is one resource for local and tribal agencies in building and maintaining the skills necessary to operate such a vast system. FHWA has an agreement with AASHTO to provide local government and tribal transportation practitioners with access to this library.

What is TC3

TC3 is AASHTO’s online training library of 190+ training modules. Courses are developed by subject matter experts and include national best practices. All courses are available on the TC3 website and also a mobile app, available on iOS and Android systems.

About the Courses

Courses are developed using a Core Curriculum Matrix model that focuses on six technical categories: construction, employee development, maintenance, materials, pavement preservation, and traffic and safety. Each category is divided into four skill levels that define a career progression, from entry level (Level I) through management and administrative (Level IV). Users can then take courses that match their field and skill level.

For maximum flexibility, users can build a personal library of courses. They can also start and stop courses as needed based on their schedule. The platform includes a dashboard that tracks progress through each course a user starts so they can see where they are at a glance and pick back up where they left off.

More than 90 percent of the courses also qualify for professional development hours (PDHs) that can contribute to continuing education and licensure renewal.
