As the TDM industry continues to develop and evolve, a TDM professional is expected to keep up to date with the latest policies and practices, and to contribute to the advancement of the industry through knowledge sharing and leadership.

To maintain and renew certification, a TDM-CP must earn a minimum number of Continuing Education Credits (CECs) per 2-year period:

  • In the Industry Leadership Category, a minimum of 30 credits per 2-year period is required. As an example, serving on an ACT Chapter Board for the full 2-year period is equivalent to meeting the criteria. When serving in roles that do not cover the entire 2-year period, credits will be awarded based on their monthly incremental value that is applicable to the period.
  • In the Professional Development Category, a minimum of 30 credits per 2-year period is required. As an example, attending the ACT International Conference each year is equivalent to meeting the criteria.

Here is an example of how easy it is to earn your recertification credits over a 2-year period:

Professional Development

Attend International Conference in year 1 = 20 credits

Attend two chapter meetings = 10 credits


Serve as National Awards Judge in year 1 and 2 = 10 credits

Volunteer with a TDM related organization outside of ACT = 10 credits

Write an article for Connect Newsletter = 10 credits

For detailed information on recertification, please see the TDM-CP Candidate Handbook.

There are many options for TDM-CPs to earn their recertification credits.  You can review the list of available opportunities below, which include self-directed learning, conference attendance, participation in chapter/council meetings, and volunteering within ACT and other activities.

All ACT-sponsored webinars held since the date you received certification are eligible for credit as detailed in the TDM-CP Candidate Handbook. As well, the virtual Emerging Mobility Summit in March 2020, the virtual International Conference in July 2020, the virtual TDM Forum in November 2020, and the virtual Future of Commuting Summit in April 2021, all qualify for credit in accordance with the points allowed in the Handbook. In addition, participation in any previous ImpACT! Leadership program is eligible for recertification.

You are required to track and provide documentation for points you submit. It is recommended that monitor your recertification activities and report them in your Prolydian account on an ongoing basis to ensure you receive recertification.

You can view information on webinars and conferences that you have registered for by logging in to your profile on the ACT website.
