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.

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 GIP certification exam has now transitioned to a computer-based test that will be offered at Prometric Testing Centers or through Online Remote Proctoring. Registration for the exam will still occur through ECI.

The fee for the NGICP exam is $160.



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


Exam Training Course


Applicants for the GIP certification exam are required to complete a GI exam training course provided by an approved trainer or that meets the exam blueprint. ECI 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 are noted on the calendar to the right.
