About the STP Credentials

There are four levels of STP Credentials, each based on five core content areas

The STP exams test application-based knowledge and specialization areas around sustainable transportation. With each level gained, the STP demonstrates greater competency in the five core content areas, based on the categories in the Greenroads Rating System.

  • Environment & Water (EW)

  • Access & Livability (AL)

  • Materials & Design (MD)

  • Construction Activities (CA)

  • Utilities & Controls (UC)
