Notice to STPs: As of February 2023, STP certificates, badges and verification requests are now hosted and managed on a new website platform, called Accredible, that integrates with our learning management system for an improved customer experience. Please make sure you whitelist the following domains: accredible.com, transportcouncil.org, and greenroads.org and make sure that this website includes your current email and a backup email address (typically a personal email). If you don't remember what email address you took the exam with, please inquire at learn@greenroads.org. We remember you. :)
The directory below is now out of date and will be replaced and updated soon on the new website. If we have your current contact info and you do not see your credential on Accredible for verification, contact us.
As of January 1, 2023, the Governing Board now requires the Level 1 STP Credential to work on registered projects. Projects that registered prior to this date, and have active contracts in good standing, are encouraged to become STPs to benefit your project team in lieu of having to pay an annual project pass fee, which costs more.
The STP Directory below shows people who have completed the Level 1, Level 2 and Level 3 Sustainable Transportation Professional Exams and are Active STPs in good standing through September 2022.
On March 17, 2020, our exam renewal policy changed for badge ID numbers 1-350, which expire after 2 years. A final renewal is now available.
STP credentials provide you a Project Pass that you can use on any project on any team in that version only. When new versions are issued, all STPs will need to test into the new version for a small fee to stay current, otherwise your Project Pass will not work. Badges will expire when the version of the rating system is sunset. Version 1.5 was retired December 31, 2017. Version 2 will sunset in 2025. The Version 3 exam and quiz is in pilot testing with university students. If you are a teacher at a university, please contact us for information on how your students can participate.
You can also request an official inked copy of your STP Certificate for $10 by emailing us ($20 internationally).
