The LEED Exam in 2026: Every Credential Exam, Cost, Dates, Format and How Accreditation Works

There is no single LEED exam. There are six, one for each LEED professional credential, and in 2026 four of them changed to LEED v5 through a beta process that most study material online has not caught up with. This guide covers all of them from the GBCI candidate handbooks and USGBC’s exam information pages as of September 2026: which exam fits which career, the format and scoring, what each exam actually tests by knowledge domain, current fees and discounts, how registration and scheduling work, the v5 beta timeline, retake and rescheduling rules, and how the credential ladder and maintenance work afterwards.

Which LEED exam do you need?

The exam follows the credential, and the credential follows the work. Passing any of the six exams makes the person LEED accredited; buildings are the ones that get certified, under the LEED certification requirements and levels covered separately, and the exams test that distinction.

The combined exam, which used to let a candidate sit the Green Associate and an AP specialty in one four hour session, is not offered during the LEED v5 beta phase. Until GBCI restores it, the Green Associate comes first as its own exam. BD+C holds more credentials than the other four specialties combined, which is why it is the default for anyone in design or construction; the LEED AP BD+C page covers that exam and the LEED AP O+M page covers the operations specialty. For a role by role decision, see LEED GA vs LEED AP vs WELL AP.

Who runs the LEED exam

Two organizations share one login, which is where most confusion starts. The U.S. Green Building Council (USGBC) writes LEED: the rating systems, reference guides and education. GBCI verifies against LEED: it certifies projects and it writes, delivers and grades the professional exams. The exams are developed from a job task analysis after each rating system version is ratified, written by a global network of subject matter experts, and accredited under ISO 17024. Registration happens inside a free usgbc.org account, the exam is booked with Prometric, and the credential is issued by GBCI. USGBC’s own overview is on its LEED professional credentials page.

LEED exam format and scoring

Every LEED exam has the same shape: 100 multiple choice questions, 85 of them scored, two hours, and a scaled passing score of 170 out of 200. What changes between exams is the depth of the questions and how the 85 scored questions are spread across knowledge domains.

Two things about scoring that candidates get wrong. First, 170 is a scaled score, not 85 correct answers; the scale adjusts for the difficulty of the specific question set, so the raw number of correct answers needed varies slightly from exam to exam. Second, GBCI does not modify scores under any circumstances. A successful challenge to a faulty question earns a free retest, not a corrected score, and the challenge must be lodged through the comment button during the exam and confirmed by email to GBCI within ten business days.

What each LEED exam tests: knowledge domains by exam

The candidate handbooks publish the number of scored questions per domain. Read across the row and the pattern is clear: Energy and Atmosphere is the heaviest domain on every v5 exam, the Green Associate is the only exam where LEED Process carries as much weight as energy, and the AP exams shift the weight toward the credit categories a practitioner has to document.

The weighting also predicts where candidates struggle. In Archiroots cohorts, Green Associate candidates lose the most practice exam points in LEED Process, the domain that looks easiest and is tested hardest, with 15 scored questions on organizational roles, certification steps, interpretations and rating system selection. AP BD+C candidates lose them in Energy and Atmosphere and Materials and Resources, the two heaviest domains on that exam. AP O+M candidates lose them in Energy and Atmosphere and Indoor Environmental Quality, which together carry 38 of the 85 scored questions.

The two exams still on v4 use the older category structure: AP Homes weighs Energy and Atmosphere at 17 questions with Innovation and Regional Priority as separate domains, and AP ND spreads 65 of its 85 scored questions across Smart Location and Linkage, Neighborhood Pattern and Design, and Green Infrastructure and Buildings. The full outlines are in the AP with specialty candidate handbook and the Green Associate candidate handbook. Any prep material that does not map its lessons to these domains is not built for the current exam.

LEED exam cost in 2026

The LEED Green Associate exam costs $250 and each LEED AP with specialty exam costs $350 in 2026, with $50 and $100 off respectively for employees of USGBC member organizations. A retake costs the full fee again.

Member pricing applies to employees of organizations holding a Silver, Gold or Platinum USGBC membership, and the membership has to be linked to the usgbc.org account before registering; it cannot be applied afterwards. USGBC’s individual membership, priced at $129 a year, states explicitly that it does not include exam discounts. Organizations registering five or more candidates at once contact GBCI directly, which is the route firms use with group training.

The fee buys one attempt. A retake is a new registration at the full fee, and after three unsuccessful attempts inside twelve months GBCI imposes a 90 day wait before the next registration. Rescheduling and cancellation follow a sliding scale set on January 1, 2025:

LEED exam dates and registration

There are no universal LEED exam dates. The exams are on demand. A candidate registers, receives an eligibility ID that stays valid for twelve months, and books any available appointment at a Prometric test centre or an online ProProctor session. The sequence:

1. Create a free account at usgbc.org. The first and last name must match the government ID that will be shown on exam day, in Roman characters, with no accents or special characters. A mismatch means being turned away and forfeiting the fee unless GBCI is told at least ten business days ahead. This is the single most common way candidates from Arabic, Persian and Turkish speaking countries lose an exam fee.
2. Under Credentials, choose the exam and complete the application. Employees of member organizations link the membership first. Pay the fee.
3. Use the eligibility ID at prometric.com/gbci to schedule. Choose a test centre or an online session, then the date and time. Prometric lists times in AM and PM; a 01:00 slot is one in the morning.
4. For online testing, download ProProctor a week ahead using the 16 digit confirmation number, run the system readiness check, and prepare the room: one screen, an external camera for desktops, no paper, no physical calculator, windows covered, nobody else entering.
5. Arrive or log in 30 minutes early. At a test centre, expect a metal detector, pockets emptied and sleeves rolled. Online, expect a 360 degree room scan by a readiness agent. Breaks stop nothing: the clock keeps running at a centre and breaks are not permitted at all online.
6. Finish and, outside the beta phase, read the pass or fail result on screen. The credential appears in the usgbc.org account and the certificate downloads as a PDF once results are processed.

Exam day habits that separate a comfortable pass from a stressful one, drawn from Archiroots cohorts: answer every question because unscored items are indistinguishable and there is no penalty for guessing; flag and move on, then return with banked time, since 100 questions in 120 minutes is 72 seconds each; read scenario questions for the phase of the project before the answer options; use the optional tutorial minutes to settle rather than skip them; and treat the practice exam score, not the calendar, as the booking trigger.

Candidates unsure about the interface can pay for a GBCI Test Drive through Prometric, a short session that reproduces the check in and testing platform without exam content. Testing accommodations for documented disabilities are free but must be requested at registration with two forms, and scheduling is blocked until GBCI approves them, which can take ten business days.

The LEED v5 exam transition: where things stand in September 2026

As of September 2026 the Green Associate, AP BD+C, AP O+M and AP ID+C exams are LEED v5 exams in a beta testing only phase: standard fee, English only, no combined format, and results released after GBCI’s analysis instead of on screen. AP ND and AP Homes remain on LEED v4.

What this means for someone registering today. The exam is a v5 exam and there is no way back to v4. During the beta phase, including the current testing only phase, the exam ends with a Notice of Completion rather than a score; the score arrives when GBCI finishes its analysis. Anyone who needs the credential in hand by a fixed date should count on the results month in the table, not the exam date. AP ND and AP Homes are unaffected and continue on v4. Existing credential holders retake nothing; a LEED AP earned under v4 is the same credential and continues with normal maintenance. USGBC keeps the running schedule on its LEED v5 exam information page.

One consequence for study material: a large share of what still ranks online for these exams was written for v4 and teaches a category structure the v5 exam no longer uses. The Green Associate and AP BD+C programs on this site were rebuilt on v5 for the beta launches; check the version before trusting anything else.

The LEED accreditation ladder

LEED accreditation has three tiers: the LEED Green Associate, earned by exam with no prerequisites; the LEED AP with specialty, earned by exam after the Green Associate; and LEED Fellow, awarded by nomination. A person is accredited, a building is certified.

The exams sit on a three tier ladder. The LEED Green Associate is tier one and has no eligibility gate. The LEED AP with specialty is tier two, requires an active Green Associate at registration, and supersedes it: once the AP is earned the Green Associate credential expires and is replaced. LEED Fellow is tier three, awarded by nomination to long standing LEED APs rather than by exam; 305 people hold it and 118 are Fellows Emeritus.

Two naming rules from the handbooks that almost nobody follows. GBCI states that “LEED GA” is not an approved abbreviation and should not be used, and that the phrase “LEED Accredited Professional” is never to be used as a designation. The approved forms are “LEED Green Associate” and “LEED AP” followed by the specialty, for example LEED AP BD+C. Recruiters search for the abbreviations anyway, which is why both appear in this article, but the credential itself should be written the approved way on a certificate, a business card and an RFP.

The pre 2009 LEED AP and the PRc2 point

Anyone who passed the original LEED AP exam before the 2009 restructuring, described in the history of LEED, holds a LEED AP without specialty, usually called a legacy LEED AP. It predates both the Green Associate and the five specialties, never expires, carries no continuing education requirement, and is the single largest group in the USGBC directory at 39,164 people. It has one practical limit that catches project teams every year.

Under LEED v5, credit PRc2 awards one point when at least one principal participant on the project team is a LEED AP with a specialty appropriate to the project. A legacy LEED AP does not count. A firm with several legacy APs and no BD+C cannot claim the point on a new construction project, which is the most common reason experienced professionals sit the specialty exam in 2026.

How many people have passed a LEED exam?

As of September 2026 the USGBC people directory lists 101,676 credential holders, of whom 94,926 hold a LEED credential. Legacy LEED APs are the largest single group at 39,164, followed by LEED AP BD+C at 25,591 and LEED Green Associates at 23,388.

Two numbers circulate and they measure different things. USGBC’s credentials page says more than 203,000 professionals have earned a LEED credential, a cumulative figure that USGBC reported as 185,071 in April 2013 and GBCI as 204,000 in its 2020 credentialing review, the last year it published onboarding data: 9,444 new LEED professionals that year, 3,407 of them outside the United States, across 134 countries. The directory count of 101,676 is the number listed as active today. The gap between the two is mostly Green Associates and specialty APs who stopped reporting continuing education, since a legacy AP never lapses, plus holders who opted out of the public listing. Roughly half of everyone who has ever passed a LEED exam is no longer maintaining the credential, which says more about the maintenance habit than about the exam.

The USGBC people directory was exported on September 4, 2026. Roughly 100,000 credentialed people worldwide, of whom more than a third hold a legacy AP that cannot satisfy PRc2, is a small pool against a public project directory of more than 220,000 registered LEED projects. That gap is the reason the specialty credential still appears as a named requirement in proposals and tenders, and why demand is strongest where certification volume is rising fastest, including the Gulf; the Saudi picture is broken down in LEED certification in Saudi Arabia.

Maintaining the credential after the exam

A LEED credential is maintained, not re-examined: 15 continuing education hours every two years for a Green Associate and 30 for a LEED AP, reported inside the usgbc.org account. A legacy LEED AP has no maintenance requirement.

Hours are reported inside the usgbc.org account, and approved providers with a GBCI course number can report them automatically. Missing the deadline moves the credential to inactive status until the hours are reported and the renewal fee paid. A running list of free LEED CE hours that count toward the LEED specific requirement is maintained on this site.

How long to prepare, and what preparation costs

Most candidates need two to six weeks with a structured course, or eight to twelve weeks from the reference guides alone. The Archiroots plan is two weeks: one week of lessons at 30 minutes a day, one week of a practice exam a day.

The exam fee is rarely the largest cost. Time is. The handbooks recommend exposure to LEED through coursework, volunteering or work before testing, and in practice preparation follows one of three routes:

The Archiroots model is the two week version of the middle row: week one is the simplified training at about 30 minutes a day, week two is one practice exam a day with flashcards, then register and schedule. The LEED Green Associate course and the LEED AP BD+C course are both built on LEED v5, include on demand instructor support, and report a 100 percent pass rate among students who complete the course and its practice exams. Before paying for any preparation, check five things: that the material is v5 and not a relabeled v4 course, that lessons map to the domain weights in the table above, that it includes full length timed practice exams, that instructor questions are answered, and what the guarantee actually requires. Free, no sign up practice exams are available for the Green Associate and for AP BD+C, with matching Green Associate flashcards and AP BD+C flashcards. Health and wellbeing professionals usually add the WELL AP, which GBCI also administers, as a third credential.

What 7,000+ exam candidates show

Archiroots has prepared more than 7,000 professionals for these exams, and the patterns below come from that work rather than from any published statistic, because GBCI does not publish pass rates.

The practical reading of this table: the exam is not where candidates fail. Booking before finishing is. A candidate who completes the lessons, holds 80 percent on repeated practice exams and tests at a centre with a stable setup removes nearly every failure mode in the list.
