For applicants

Green infrastructure (GI) has become a critical component to comprehensive stormwater management. However, successful implementation of green infrastructure requires access to adequately skilled workforce available to perform the installation, inspection, and maintenance tasks.

Initiated under the leadership of DC Water and the Water Environment Federation (WEF), the National Green Infrastructure Certification program (NGICP) sets national certification standards for green infrastructure (GI) construction, inspection, and maintenance workers.

By underscoring your competency in these areas, certification increases your competitiveness in the job market, and provides a pathway to higher paying positions.


The NGICP exam schedule will be administered on the following dates:

  • Friday, July 27, 2018
  • Friday, September 28, 2018 (timed with WEFTEC)
  • Friday, November 16, 2018
  • Friday, February 1, 2019

The fee for the NGICP exam is $200.




NGICP certification requires a high school diploma or equivalent and completion of the exam training course.


Exam Training Course


Applicants for the NGICP certification exam are required to complete a NGICP exam training course provided by an approved trainer. WEF is currently working with partners and our community of trainers to identify training opportunities to address the training requirement to coincide with the exam schedule.

Registrations for available exam trainings and exam administrations are noted on the calendar to the right. Additional options will be added as and when confirmed.

Course Details


NGICP represents the standard for national certification of green infrastructure (GI) construction, inspection, and maintenance workers. This course prepares participants to demonstrate their competency in in the following green infrastructure areas:

  • bioretention (rain gardens, bioretention cells, curb extensions/bulb-outs, bioswales, stormwater planters),
  • rainwater harvesting (rain barrels and cisterns),
  • permeable pavements (porous concrete, pervious asphalt and permeable pavers),
  • green roofs and blue roofs,
  • dry wells and stormwater wetlands.

A complete list of topical areas can be found on the Exam Blueprint and Body of Knowledge.


Exam Results


The exam is currently administered as a paper-and-pencil test. Results are usually available within 45 days.

Credentials are good for two-years from the date on your certificate. The two-year certification cycle begins on the date NGICP awards the credential and expires on the first day of the month immediately following this date.


Maintenance Fee


A maintenance fee of $100 is due at the end of the first year in order to keep your credential in good standing.

Recertification Process


All certificants need to apply for recertification by their two-year anniversary and pay a $100 recertification fee. There is no need to take an exam to get recertified but, the certificant is responsible for making sure that they stay up-to-date on the latest GI best practices through continuing education.

A certificant must document participation in a minimum of 14 hours of professional development hours (PDH) in topics directly related to constructing, inspecting, and maintaining green infrastructure during each two-year cycle in order to maintain the NGICP credential.

Instructions for fulfilling PDH requirements.
