  AASHTO TSP2 Certification Exams   

The National Center for Pavement Preservation (NCPP) will again offer the AASHTO TSP2 certification exams following the Slurry Systems Workshop for each of the following preservation treatments: chip seal, slurry systems, and crack treatment. An exam will be administered that is 50 questions for agency personnel and 80 questions for contractor personnel (with the exception of the crack treatment contractor exam which is 50 questions). The exam is closed book/closed note and a score of 70% or higher is needed to pass. The exam tends to take participants 45 to 90 minutes to complete. Individuals who pass the exam will receive a certification card which is valid for three years from the date it was issued and will be recognized by all states requiring AASHTO TSP•2 preservation certification. Their name and expiration date will also be added to a searchable database on the TSP•2 website.

For more information about the certification process, please call NCPP at 517-432-8220, or visit

   Registration for the NCPP Certification Exams is separate, and in addition to the Slurry Systems Workshop Registration.
