Certified Professionals are required to complete 7 hours of professional development hours every year to meet recertification requirements.  These are typically completed via participation in webinars, conference sessions, and/or classes that are aligned with the certification exam.

Recertification Requirements

To maintain certification, all certified individuals are required to renew every year.  A Certified Professional must document participation in a minimum of 7 hours of continuing education training in topics directly related to constructing, inspecting, or maintaining green infrastructure (GI) during each one-year certification cycle.


The purpose of the renewal requirement is to help assure that all certified individuals are continuing to take part in current training opportunities and stay up-to-date with the latest approaches and strategies for installing, inspecting, and maintaining GI practices.


The quantity of recertification is set at 7 hours for every recertification period to encourage Certified Professionals to take classes, workshops, seminars, etc. and become familiar with several new topics or to take a more detailed training in a specific area of green infrastructure.

Expiration Date

According to the NGICP Policies and Procedures, the NGICP certification is valid for one year.  Certified Professionals must apply for recertification and successfully demonstrate that they meet the recertification requirements prior to the recertification deadline.

Recertification applications, contact hour documentation, and the recertification fee are all due on the day of the deadline by the close of business at ECI’s offices in Sacramento, CA.  After the deadline, progressive late fees will be charged above and beyond the recertification application fee according to the schedule below:

  • After deadline through COB 90 days later: Late fee of $75

After 30 days (or 1 month), the certification expires and recertification is not possible.  The individual will need to submit a new NGICP application, complete 35 hours of GI training, pay all applicable fees, take, and pass the exam in order to become certified again.

The one-year certification cycle begins on the date NGICP awards the credential and expires in one year on the first day of the month immediately following the certification date.
