- BPI retired Crew Leader effective October 1, 2026; exams were permitted only through September 30, 2026.
- Existing Crew Leader credentials stay valid until their individual expiration dates.
- The written exam had 100 multiple-choice questions, two hours, and a form-specific passing standard of 69% or 75%.
What the Crew Leader Credential Was
Crew Leader, abbreviated CL on this site, was a professional certification issued by the Building Performance Institute (BPI). It was aimed at the person who runs a residential energy-efficiency or weatherization crew in the field: reading the work order, lining up materials and people, preparing the home, directing the installation work, and closing the job with proper documentation.
The credential is not a general leadership certificate and it is not any of the other well-known credentials that happen to share the "CL" abbreviation. It belongs specifically to the BPI Crew Leader certification scheme. If you are trying to untangle the shorthand, our explainers on what CL is, what CL stands for, and CL meaning cover the terminology, while this article focuses on the certification itself.
Current Status: Retired as of October 1, 2026
The most important fact about Crew Leader is its status. BPI's Spring 2026 "Performance Matters" newsletter announced the retirement, and BPI's current certification directory lists Crew Leader under Retired Certifications. The retirement took effect October 1, 2026. Examinations were permitted through September 30, 2026.
The same notice also retires the Retrofit Installer Technician (RIT) certification. RIT should not be treated as a drop-in replacement for Crew Leader, and this site does not substitute another credential in its place.

What Existing Holders Should Know
Retirement of a certification is not the same as revocation. Under the retirement terms, existing Crew Leader credentials remain valid until their individual expiration dates. If you hold the certification, your card or certificate date is the date that matters, not the retirement date.
- Check your own expiration date. Each credential carries its own date; there is no single universal sunset for current holders.
- Do not assume renewal is available. The published scheme described a renewal pathway, but that is a legacy provision. Post-retirement renewal availability has not been verified, so confirm directly with BPI before planning around it.
- Keep your records. Training transcripts, continuing education records, and your certificate are useful evidence of your qualifications for employers and program administrators.
- Talk to your employer or program. Some weatherization programs and contractors reference crew-lead qualifications in their own requirements; ask how they are handling the retirement.
Legacy Requirements at a Glance
When the certification was active, candidates had to clear a fairly demanding set of prerequisites before they could test. These are listed here as historical context only. For a deeper walk-through of how the requirements fit together, see CL requirements.
| Requirement Area | Historical Standard |
|---|---|
| Education | High-school diploma/GED or foreign equivalent; or a qualifying state career-readiness certificate with at least 3 on each WorkKey; or the documented experience substitute |
| Safety training | OSHA 30 |
| Industry experience | 4,000 industry hours, or 2,000 hours with BPI Retrofit Installer Technician certification including at least 1,000 as a certified RIT |
| Coursework | 100 hours of building-science coursework aligned to the job task analysis |
| Application points | At least 15 qualifying application points |
| Approval | BPI approval of the application |
| No-education-credential alternative | Additionally required 1,000 hours in a qualifying compliance-based program and an employer letter |
One caution: the supporting prerequisites document was revised in April 2019 and uses older BPI/NREL Installer terminology, so some wording in it predates the later scheme handbook and application. Treat any single document as a snapshot rather than the final word.
How the Written Exam Was Built
The knowledge examination was a closed-book, multiple-choice test of 100 questions with a two-hour time limit. The one exception to "closed-book" was BPI standards, which were supplied through the testing site so candidates could reference them during the exam.
Administration ran through BPI Test Centers and approved proctors, and the center set the fee. That means there was no single national price; costs varied by location and by what the center bundled in. Our CL certification cost breakdown discusses how to think about those variables without inventing a fixed figure.
Passing standard
The passing standard was form-specific rather than universal. The legacy page lists 69% or 75%, depending on the exam form. That is why you will see different numbers quoted in different places, and why it is risky to memorize one threshold as "the" Crew Leader cut score. For more on interpreting this, see CL passing score. Likewise, because no pass-rate data is verified here, our CL pass rate article stays qualitative rather than quoting numbers.
Key Takeaway
The blueprint for the written exam publishes seven duties, A through G, but no percentage weights. Do not convert task counts into percentages or assume one domain "counts" more than another; the published source does not support that.
The Seven Written-Exam Domains
The Crew Leader Certification Scheme Handbook (revised July 1, 2022, Section 8) lays out the multiple-choice blueprint as seven duties. They read like the life cycle of a weatherization job, from receiving paperwork to filing the final file. For a fuller treatment, see our complete guide to all 7 CL content areas.
Domain 1: Develop and/or Review the Work Order
The job starts on paper. Candidates were expected to understand what a work order communicates and whether it is complete and workable.
- Reading the scope of work and spotting gaps or conflicts
- Confirming the work order matches conditions in the home
- Understanding what the crew is, and is not, authorized to do
Domain 2: Identify materials and staffing needs
Translating the work order into what must be on the truck and who must be on the crew.
- Estimating materials and equipment from the scope
- Matching tasks to crew skills and certifications
- Planning for specialty tools and consumables
Domain 3: Develop plan to execute work order on site
Sequencing is where crew leads earn their keep: the right measures in the right order.
- Sequencing work so earlier tasks do not undo later ones
- Identifying safety and logistical constraints before arrival
- Coordinating with the homeowner, other trades, and program staff
Domain 4: Prepare house to execute work
Getting the home ready protects both the occupants and the crew.
- Protecting finishes, belongings, and occupants
- Confirming site conditions and hazards before work begins
- Staging materials and establishing work areas
Domain 5: Execute work order and manage project
The largest practical piece: doing the work correctly while directing others.
- Overseeing installation quality and crew safety
- Handling surprises and scope changes on site
- Using diagnostic testing to verify results
Domain 6: Job Finalization Activities
Closing out a job properly, not just packing the truck.
- Final inspection and verification of completed measures
- Cleanup and site restoration
- Walking the homeowner through what was done
Domain 7: Final Documentation
If it is not documented, it did not happen, at least as far as program auditors are concerned.
- Recording measures installed, materials used, and test results
- Completing required forms accurately
- Preparing the file for review and payment
These domain names come from the handbook's blueprint and are reproduced here as historical written-exam objectives. A separate field outline exists for the hands-on portion, but it does not replace these headings for the written exam.
The Separate Practicum
Passing the written exam was only half the picture. Crew Leader also required a two-part practicum, which is easy to confuse with the knowledge exam but is a different assessment entirely.
| Component | Format | Rules |
|---|---|---|
| Knowledge exam | 100 multiple-choice questions, two hours | Closed-book, except BPI standards supplied through the testing site |
| Practicum, computer part | 35 multiple-choice questions, one hour | Closed-book |
| Practicum, field part | Hands-on assessment, three hours 30 minutes | Open-book, no outside assistance; three props and diagnostic testing |
The combined practical passing score was 78%. The field work involved three props and diagnostic testing, and the Crew Leader Field Guide (dated September 27, 2013) is the supporting source describing how that portion was organized. Because the field guide predates the later handbook, treat it as supporting context rather than the last word on format.
Legacy Renewal Provisions
The published scheme specified a three-year certification cycle. Under those provisions, 24 qualifying continuing education units (CEUs) could waive the knowledge retest, but the two-part practical assessment remained mandatory, along with ethics reattestation. BPI's general 2023 renewal policy document excludes Crew Leader and refers back to the scheme.
Weatherization Job Skills and Pay
Even with the exam retired, the underlying job has not disappeared. Crew leads on weatherization and energy-efficiency retrofit projects still need the competencies the seven domains describe: reading and reviewing work orders, planning staffing and materials, sequencing the work, protecting the home, supervising installation quality, closing out jobs, and producing clean documentation.
Employers in this space typically include weatherization assistance program providers, community action agencies, and residential energy-efficiency and insulation contractors. If you are exploring openings, our CL jobs article discusses where crew-lead roles appear and how listings describe them.
Pay without the hype
Compensation for crew leads varies with region, employer type, program funding, union status, and experience. This site does not cite a specific salary number or claim a measurable credential premium, because no verified figure is available in the source material. For a qualitative look at the factors that move pay, see the CL salary guide, and for a balanced take on value after retirement, read is the CL certification worth it.
Using Historical Material Responsibly
Because there is no currently bookable Crew Leader exam, the value of historical study material is different now. It is useful for people who hold the credential and want to refresh job knowledge, for supervisors and trainers who want to benchmark what a crew lead was expected to know, and for workers building skills toward similar responsibilities.
If you want to work through the old question style, you can try the historical practice questions and use the CL study guide and CL cheat sheet as structured references. For a candid sense of the challenge level the exam presented, see how hard the CL exam was.
A domain-ordered review plan
If you do review, follow the job's own logic rather than jumping around. This is the one place a schedule helps, because the domains build on one another.
Paper and planning (Domains 1-3)
- Practice reviewing a work order for gaps
- Work through materials and staffing logic
- Draft an on-site sequence and note the dependencies
Site work (Domains 4-5)
- Review house preparation and safety setup
- Revisit diagnostic testing and quality oversight
Closeout (Domains 6-7)
- Walk through finalization steps
- Practice completing documentation accurately
Frequently Asked Questions
No. BPI retired Crew Leader effective October 1, 2026, and examinations were permitted only through September 30, 2026. This site does not advertise a currently bookable exam.
Yes. Existing credentials remain valid until their individual expiration dates. Check your own certificate date, and contact BPI about whether renewal is possible, since the legacy renewal rules are not verified as available after retirement.
It had 100 multiple-choice questions over two hours, organized around seven duties: developing or reviewing the work order, identifying materials and staffing needs, planning on-site execution, preparing the house, executing and managing the project, job finalization, and final documentation.
The written exam's passing standard was form-specific; the legacy page lists 69% or 75%. The separate practicum required a combined practical score of 78%.
No. The same BPI retirement notice also retires Retrofit Installer Technician (RIT), so it should not be treated as a currently available substitute for Crew Leader.
