Population growth and development are causing our communities to use more resources than ever before, which means more waste and a negative impact on the environment. Traditional land development and land use decisions often underestimate or ignore healthy ecosystems. Sustainable land development is cost effective, better for the land and fosters resiliency.
Through thoughtful design and management, landscapes can be developed to help sustain the natural world we live in by incorporating native vegetation, healthy soils and existing ecosystems. Our communities depend on the functions of ecosystems, which have nutrient-rich soil and provide us with clean air and water.
Landscapes, infrastructure and buildings are often designed without regard to their harmful impacts on scarce resources, underlying ecological systems and quality of life in the community.
The Sustainable SITES Initiative aims to weave development of healthy natural ecosystems with the landscape of daily human activity, via the spaces and places we inhabit, by providing a systematic, comprehensive set of guidelines to model development practices after healthy systems and processes.
Sustainable landscapes provide ecosystem services and create ecologically resilient communities better able to withstand and recover from floods, droughts, wildfires and other catastrophic events. SITES-certified landscapes additionally help reduce water demand, filter and reduce stormwater runoff, provide wildlife habitat, reduce energy consumption, improve air quality, improve human health and increase outdoor recreation opportunities.
The SITES certification process allows projects to benchmark against performance criteria. The process is performed through SITES Online, which is a clean and easy tool to allow for easy documentation. SITES Online also helps with managing the SITES project team and tracking the project from start to finish.
The SITES Rating System is a 200-point system with four certification levels of achievement (projects must meet a minimum of 70 points to achieve certification). The 18 prerequisites within the rating system are required, plus the minimum number of credits to achieve the required certification level.
A SITES certification involves registering the project with the Green Business Certification Inc. (GBCI); working through the SITES prerequisites and credits through a process with an integrated design team; applying for SITES certification by submitting a completed certification application and paying the fee; and receiving the certification decision after the formal review process is complete.
Please visit the Guide to SITES certification for more information.
Green Business Certification Inc. (GBCI) administers a SITES certification. GBCI is the only certification and credentialing body within the green business and sustainability industry to exclusively administer project certifications and professional credentials and certificates of LEED, PEER, WELL, SITES and GRESB.
Registration and certification fees are flat, not based on project size. View our fee table.
The SITES Rating System can apply to development projects located on sites with or without buildings. Your site must have been constructed within the last two years and be at least 2,000 square feet in order to be eligible to apply for a SITES certification. Eligible sites include:
- Open spaces: local, state and national parks; botanic gardens; arboretums
- Streetscapes and plazas
- Parking lots
- Commercial: retail and office areas; corporate campuses
- Residential: neighborhoods or individual yards
- Educational/Institutional: public and private campuses; museums; hospitals
- Industrial parks
- Golf courses

GBCI provides support to project teams pursuing SITES certification throughout the process—from pre-design through post-certification—through a variety of tools and project-specific one-on-one support. Our team will work with project teams to help identify local resources, answer eligibility and prerequisite requirements and field technical questions. At each stage of review, project teams have the opportunity to speak directly with their reviewer. Post certification, GBCI provides a SITES Certificate along with review comments, a press release and media kit to help celebrate the successes of a project team. SITES Certified projects are then listed on our website and showcased through our PR team.
Yes, SITES may be applied worldwide and we'd love to have projects from outside of the United States participate in SITES certification. Our team is more than happy to work with project teams on a one-on-one basis to adapt US references, standards and guidelines to localized resources, where applicable.
A SITES AP is an individual who possesses the knowledge and skills necessary to support the SITES certification process, including participating in the design and development process, supporting and encouraging integrated design, managing the application and certification process, and providing advocacy and education for the adoption of SITES.
Visit SITES Online to create an account and register for the SITES AP exam.
Once registered, you will be able to schedule your test session at a Prometric testing center near you. Exam sessions are available year round through Prometric test centers worldwide. If you would like to locate your nearest testing center and view availability, please visit prometric.com/gbci and click on "Locate."
To be eligible to sit for the SITES AP exam, applicants must be at least 18 years of age. There are no other prerequisites to sit for the WELL AP exam, though prior SITES project experience is highly recommended.
Please see the SITES AP exam fee structure on our website.
A candidate must earn a scaled score of 170. The scaled score for all GBCI exams ranges from 125 – 200. The scaled score is calculated by taking the candidate’s raw score (total number of correct questions) and mapping it onto a standardized scale between 125 and 200, with the minimum competency threshold always mapped to a scaled score of 170. Scaled scoring is used as a best practice to manage and report the potential differences in difficultly across different exam forms.
Once you register and pay for your exam, you have one year to schedule your exam session. You may contact GBCI to request one six month extension of this one-year period.
Prometric.com/gbci is available 24 hours per day for scheduling, rescheduling and confirming exam appointments. To schedule an exam, you will need to have first applied and registered with GBCI. To reschedule, cancel, or confirm, an exam appointment, you will need your Prometric-issued 16 digit confirmation number.
You can confirm, cancel or reschedule an exam on the Prometric website. You may reschedule or cancel your exam up 30 days prior to your exam without a fee. If you reschedule or cancel an exam fewer than 30 days but more than 3 days before the scheduled date, you will be charged a $50 fee. You cannot reschedule your exam after midnight on the third day before the scheduled appointment. (For example, Wednesday appointments cannot be rescheduled after Sunday at 11:59 p.m. EST)
When you reschedule an exam, you will receive a new email confirmation. If you do not, please contact Prometric immediately to confirm your exam was rescheduled.
|Days until exam||Refunds||Reschedules|
|30 days or more||Yes||Yes|
|3-29 days||Yes ($50 fee)||Yes ($50 fee)|
|2 days or less||No||No|
Candidates sitting for the exam from 4/15-5/1 will receive results via email the week of 5/8. Starting 5/2, all results will be provided to candidates in real time, as well as emailed at the completion of the exam.
Test takers who sat for the exam prior to 3/31/2017 and do not receive a passing score will be offered a free retake, which may be taken within 90 days of receiving the score report. Additional instructions to re-register will be provided in the email you receive with your score. For test takers who sat for the exam from 4/1/2017 and on, if your attempt was unsuccessful you may register again in the same way as initial registration. After three unsuccessful attempts, however, you must wait 90 days before submitting a new registration to GBCI. Candidates must pay the registration fee for each exam attempt.
GBCI does not release exam content or answers or allow candidates to review proprietary content under any circumstances.
Exam scoring is standardized through a computerized algorithmic process, which is applied exactly the same way to all GBCI exams that are taken. GBCI will investigate exam scores only in instances of technical malfunctions at the test site.
Yes, there are CMP requirements for the SITES AP. There has been an overall effort to align the SITES, LEED and WELL APs as much as possible. For more information about CMP requirements for both the SITES, LEED and WELL credentials, please visit the GBCI CMP Guide.
Conception: GBCI will bring together leading experts in the fields of sustainable landscape design to form a Job Analysis Committee. This committee will include landscape architects, planners, consultants, horticulturalists and water, soil and human health specialists from the public, private and nonprofit sectors. The committee will be responsible for creating content areas that lay the groundwork for building the SITES AP exam.
Validation: GBCI will enlist the help of a wider group of subject matter experts, who will review the content areas and their relative importance through the SITES AP Job Analysis Survey. The survey will give experts in the sustainable landscape community an opportunity to contribute to the SITES AP credential. GBCI will then gather and analyze results to create an exam blueprint, which will outline weight distribution for exam questions by content area.
Development: Once the blueprint is finalized, GBCI will enlist subject matter experts to write and review questions to appear on the SITES AP exam. With expert consensus, a well-rounded exam will be created and launched for the SITES AP credential. The exam will be finalized and placed into the testing platform for aspiring SITES AP candidates.
