A LEED plaque looks simple from the lobby, but there is no application form behind it. Certification is a documented performance case, assembled by the project team and verified by a third-party reviewer. The path, at least, is the same five steps for every project. This guide walks the LEED certification process step by step: choosing the rating system, registering on Arc, building the scorecard, the GBCI review, how long it all takes, and who on the team makes it happen.
What is the LEED certification process?
The LEED certification process is the path a building project follows from registration to award: the team selects a rating system, registers on Arc, demonstrates compliance with every prerequisite, documents its chosen credits, and submits for GBCI's third-party review, which grants the certification and its level.
Before we walk through the steps one by one, two ideas will help everything else make sense. First, certification is performance-based: the project earns its level by documenting what it actually does about energy, water, materials, and indoor quality. Think of it as building a case file, not filling out a form. Second, the process is third-party verified: USGBC develops the rating system, but Green Business Certification Inc. (GBCI) reviews the evidence and grants the certification. The team makes the case, and an independent reviewer checks it, which is what makes the plaque trustworthy. With those two ideas in place, we can walk through the five steps in order.
Step 1: Choose the rating system and check the MPRs
Every project starts by selecting the rating system that fits it, most commonly BD+C for new construction and major renovations, ID+C for interior fit-outs, and O+M for existing buildings in operation, and by confirming the three Minimum Program Requirements.
Why are there different rating systems at all? Think of how a car rental company sorts its fleet into categories: SUVs, minivans, compact cars, standard-sized cars. LEED sorts projects the same way, categorizing them into rating systems by their type of construction and space use, so a newly built office building falls under BD+C while a hotel interior renovation falls under ID+C. The categories also carry different expectations. No one blames a sports car for struggling on a dusty mountain road, but an SUV is expected to handle it, and in the same way, each rating system asks its projects to perform in the ways that fit them. Our LEED v5 overview covers the current line-up and what each system is for. Before anything is registered, the project must also clear the Minimum Program Requirements (MPRs), which are the three baseline conditions of eligibility:
| Minimum Program Requirement | What it means |
|---|---|
| Permanent location on existing land | The building cannot be designed to move |
| Reasonable LEED boundaries | The project boundary honestly reflects the project |
| Minimum size | 1,000 square feet (93 square meters) for BD+C and O+M; 250 square feet (22 square meters) for ID+C |
Notice that the MPRs earn no points. They simply decide whether the project is eligible at all, and that is exactly why checking them comes first: a project that cannot meet them cannot be certified under LEED, no matter how many credits it might earn. Confirming them takes only a few minutes, and it saves the team from discovering an eligibility problem after months of documentation work.

Step 2: Register the project on Arc
Registration makes the project official: under LEED v5, projects register on the Arc platform, per USGBC's certification process overview, pay the registration fee, and gain access to the tools and forms the documentation will live in.
Registering is simple, but the timing matters. The earlier the project is registered, the earlier the team is working with the scorecard in front of it, and decisions made early in design tend to cost far less than the same decisions made later. Consider building orientation: rotating the building to make better use of daylight costs nothing on day one, and it is impossible once construction begins. Registration is also when the fees become concrete, because registration and certification fees depend on the project's size and type; our guide to LEED certification costs covers the full fee schedule.
Step 3: Build the scorecard
The scorecard is the project's plan: it must satisfy every prerequisite in its rating system, then select the credits it will pursue toward a target level, using the LEED scorecard as the map of all 110 available points.
Exam tip: Prerequisites and the Minimum Program Requirements are mandatory and earn no points; only credits earn points. It is very important to know this distinction for exam purposes.
To build the scorecard, it helps to understand the two kinds of requirements it contains, because prerequisites and credits play very different roles. Prerequisites are mandatory: every one of them must be met, and none of them earns a point. You can think of them as the MPRs that live inside each rating system. Credits are optional: the team is free to choose the ones that fit the project's design, budget, and goals, and those choices are what earn points. (The full requirement stack explains how the pieces fit together.) Under LEED v5, one more rule needs to be planned for from day one, and it concerns projects aiming for the top level. For Certified, Silver, and Gold, points are the whole story: meet every prerequisite, earn enough points, and the level follows. Platinum works differently. To reach it, a project needs all of its prerequisites and at least 80 points, and it must also earn a specific set of decarbonization credits. For BD+C, those credits are Electrification, Enhanced Energy Efficiency, Renewable Energy, and Reduce Embodied Carbon. This means a project could finish with 85 points and still miss Platinum if it skipped those particular credits. Whatever the target level, experienced teams also aim a few points above it, because a credit or two often falls away during review.
Here is how the pieces work together in practice. Suppose a project meets all three MPRs, satisfies every prerequisite, and earns 70 points: it receives more than the base level, because 70 points lands in the Gold band. Now suppose a different project earns 90 points but misses a single prerequisite: no certificate is awarded at all, regardless of the score. That asymmetry is exactly what the exam likes to test, and it is why the scorecard always starts from the prerequisites rather than the points.
Step 4: Document and submit for GBCI review
Documentation converts the scorecard into evidence: for each prerequisite and credit, the team assembles the required forms, calculations, and drawings, then submits the application for GBCI's third-party review.
The review is not a single verdict; it works more like a conversation in rounds. GBCI's reviewers assess the submission and send back their findings: some credits are marked as anticipated, and clarifications are requested where the evidence is not yet convincing. The team then responds with corrections and additional documentation, and the review is finalized. Two habits make this stage go smoothly. First, document as you go. Evidence gathered while decisions are being made is accurate and easy to collect, but reconstructing the same evidence months later means chasing old emails, calculations, and drawings. Second, remember that the reviewer was never in the room. Every claim should carry its own proof in the submission, so that someone reading it cold can follow the reasoning. Teams can also split the submission, sending design-phase credits for review while construction continues, which surfaces problems while there is still time to fix them.
Step 5: Certification and beyond
When the review is finalized, the project's points determine the award level: Certified at 40–49 points, Silver at 50–59, Gold at 60–79, and Platinum at 80 or more, out of 110 available.
| Certification level | Points required |
|---|---|
| Certified | 40–49 |
| Silver | 50–59 |
| Gold | 60–79 |
| Platinum | 80+ (plus the v5 decarbonization credit gates) |
Receiving the award completes the process, though not always for good. Certification reflects the project as it was documented, and buildings certified under O+M, the rating system for existing operations, recertify every three years so the credential keeps tracking how the building actually performs. The award also matters for the people involved: running a certified project is exactly the kind of experience employers look for, which brings us to who runs the process.
How long does the LEED certification process take?
There is no single answer, because certification tracks the project's own schedule: the documentation phase runs alongside design and construction, and the review phases add weeks to months on top, with current review timelines published in USGBC's certification guides.
It helps to think about the timeline in two layers. The first layer is the project itself: a new building cannot certify faster than it is designed and built, so for BD+C projects the certification timeline follows a construction schedule that was already measured in years. The second layer is the review, which is the only part with its own clock: each review round takes a defined period, the team's responses take time, and a project that needs several rounds extends accordingly. That is why preparation shortens the timeline more than anything else: complete, well-organized documentation tends to move through review in fewer rounds, while gaps and missing evidence add extra cycles. An O+M certification for an existing building, by contrast, can move much faster, because there is no construction to wait for, only performance data to assemble.
Who runs the certification process?
The project team runs it: the owner sets the target, the designers and contractors deliver the strategies, and typically a LEED-accredited professional coordinates the scorecard, the documentation, and the review, which is why projects actively staff for the credential.
The coordination is real work: someone has to know what every credit requires, keep the documentation moving alongside the design, and respond to the reviewer's findings when they come back. That someone is usually a LEED AP, and the role is valued enough that having a LEED AP with the relevant specialty on the team can itself earn the project a point. If you are reading this as a future professional rather than a project owner, note that running this process is a skill people are hired for, and the path into it starts with the LEED Green Associate credential. The process this guide describes is also core material on that credential's exam, and it is taught in full in our best-selling LEED Green Associate study guide.

Frequently Asked Questions
What are the steps of the LEED certification process?
Five steps: choose the rating system and confirm the Minimum Program Requirements, register the project on Arc, build the scorecard by meeting every prerequisite and selecting target credits, document and submit for GBCI review, and receive the award at the level the points earn.
How long does LEED certification take?
It tracks the project's schedule: documentation runs alongside design and construction, and the review phases add weeks to months, with current timelines published in USGBC's certification guides. Existing-building (O+M) certifications generally move faster than new construction because there is no build to wait for.
Who reviews and awards LEED certification?
Green Business Certification Inc. (GBCI) performs the third-party reviews and grants the certification. USGBC develops the LEED rating system itself, and the split between the two is what makes the certification independently credible.
What are the LEED Minimum Program Requirements?
Three baseline eligibility conditions: the project must occupy a permanent location on existing land, use reasonable LEED boundaries, and meet the size minimums of 1,000 square feet (93 square meters) for BD+C and O+M or 250 square feet (22 square meters) for ID+C.
Can an existing building get LEED certified?
Yes, through the O+M (Building Operations and Maintenance) rating system, which certifies how a building actually performs in operation and requires recertification every three years to keep the credential current.
What happens if a project cannot meet a prerequisite?
It cannot certify under that rating system, regardless of how many credit points it earns, because prerequisites are mandatory. Teams facing a failed prerequisite either redesign to meet it or reassess which rating system fits the project.
Is the LEED certification process on the LEED Green Associate exam?
Yes, heavily: the LEED Process domain carries more questions than almost any other, covering registration, prerequisites versus credits, GBCI's role, review, and the certification levels. Knowing the five-step sequence and who does what is core exam preparation.
Is the LEED certification process on the LEED AP BD+C exam?
Yes, at working depth: the AP BD+C exam assumes you can run the process, testing credit-level documentation requirements, submittal strategy, and how scorecard decisions play out on a real BD+C project.
