No-cost training for local and tribal agencies

Do any of these describe your agency?

  • You need to manage projects from cradle to grave
  • Chip seal might be an answer for upgrading your gravel roads but crews need training
  • It has been a long time since you cracked that high school math book
  • You need professional development hours that won't break the bank

Local and tribal agencies are responsible for more than 75 percent of our Nation's highway network. They need training to stay at the top of their game, but that can be expensive and is not always convenient.

To help, The Federal Highway Administration (FHWA) purchased access for local and tribal governments to the American Association of State Highway and Transportation Officials' (AASHTO) TC3 online training platform.

Practitioners can take unlimited courses at no cost to them.

What is TC3?

TC3 Logo

TC3 is AASHTO's library of 190 training modules. The courses are divided into the following categories: Materials; Construction; Maintenance; Traffic and Safety; Pavement Preservation; and Employee Development. Courses are developed through a collaboration of national best practices and a network of subject matter experts, ensuring the curriculum meets the challenges of today and tomorrow. All courses are available on the TC3 website and also a mobile app, available on iOS and Android systems.

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 take courses that match their field and skill level.

Access to courses is available to local agency and tribal staff only.

Professional Development Hours

Many practitioners need courses with professional development hours (PDHs) to earn credits for maintaining their licenses and certificates. More than 90 percent of TC3 courses qualify for PDHs.
