LEED v4.1 vs v5: choose prep for the exam you will take
Which version should I study?
For Green Associate and AP BD+C, prepare for v5. The final Green Associate exam is available with results at completion. AP BD+C remains in beta with delayed results. AP Homes and ND remain based on v4. Confirm your exact credential before choosing materials.
Exam status checked October 4 against USGBC's September 28, 2026 update. Rating-system versions and exam versions are related but distinct: a project's registration deadline does not establish your exam availability.
Old and current exam options
| Credential | Previous exam | Current preparation decision |
|---|---|---|
| Green Associate | v4 testing ended April 26, 2026. | Choose prep aligned to the final v5 exam. |
| AP BD+C | v4 testing ended June 28, 2026. | Choose v5 specialty prep. Beta opt-in registration ends October 21; testing ends October 27, 2026, Eastern time. |
| AP Homes / ND | Separate specialty exams. | Use the applicable v4 handbook; do not apply BD+C dates. |
AP beta results and the final exam are tentatively expected in February 2027; dates may change. Check the official source before booking.
How to use older study notes
Keep useful foundational explanations, then compare each topic with your current candidate handbook. Check the objective, terminology and reference before relying on an older answer. A familiar concept alone does not establish coverage of the current exam.
A practical preparation check
Illustrative study workflow: You have older notes on water efficiency. Open the current handbook for your credential, locate the relevant objective, and check your notes against its listed references. Then explain a practice answer in your own words and record the source. This is a study method, not an official exam question or a score prediction.
Choose the next step for your credential
Try the Green Associate sample before choosing a paid format. If you need specialty preparation, start with the AP BD+C overview.
