Only a small percentage of practicing transportation planners in the United States hold either the CTP or PTP credential.
A select number of transportation planners choose to obtain both certifications.
The Advanced Specialty Certification recognizes planners for their expertise and leadership specifically within transportation planning.
AICP CTP certification is possible only for planners who are members of AICP in good standing, have at least eight years of work experience in the transportation planning field, and pass a rigorous exam administered annually.
[3] PTP certification is possible only for planners who have an accredited degree in planning or transportation, have at least three years (for master's degree and Ph.D. holders) or four years (for bachelor's degree holders) of work experience in the transportation planning field, and pass a rigorous exam administered three times annually.
