1How many core 'keep it' principles of healthy housing does the BPI Healthy Housing Principles (HHP) curriculum cover?

A.Five

B.Seven

C.Eight

D.Ten

Explanation: The BPI HHP Reference Guide is built around eight 'keep it' principles of healthy housing: clean, dry, pest-free, contaminant-free, safe, ventilated, comfortable (thermally controlled), and maintained. Each chapter of the Reference Guide is organized around one principle. Exam tip: NCHH historically described seven principles; BPI's published HHP curriculum adopts the eight-principle framework that adds 'comfortable' (thermal comfort).

2What is the EPA recommended action level for radon in indoor air at which homeowners should take steps to mitigate exposure?

A.0.4 pCi/L

B.2.0 pCi/L

C.4.0 pCi/L

D.10.0 pCi/L

Explanation: The EPA action level for radon is 4.0 picocuries per liter (pCi/L). At or above this level, EPA recommends that homeowners install a radon mitigation system. EPA also encourages mitigation between 2.0 and 4.0 pCi/L because no level of radon is considered safe. Exam tip: Memorize 4 pCi/L as the action level and 2 pCi/L as the 'consider mitigation' threshold.

3What is the EPA action level for lead in drinking water under the Lead and Copper Rule?

A.5 ppb

B.10 ppb

C.15 ppb

D.20 ppb

Explanation: The EPA action level for lead in drinking water is 15 parts per billion (ppb) at the 90th percentile of samples. When exceeded, water systems are required to take corrective steps such as corrosion control treatment and public education. Exam tip: 15 ppb is enforcement-related; EPA's Maximum Contaminant Level Goal (MCLG) for lead is zero, because no level of lead exposure is safe.

4Homes built before what year are presumed to potentially contain lead-based paint under EPA and HUD rules?

A.1950

B.1960

C.1978

D.1992

Explanation: Residential lead-based paint was banned for consumer use in 1978. Homes built before 1978 are presumed to potentially contain lead-based paint and trigger requirements under the EPA Renovation, Repair, and Painting (RRP) Rule and HUD Lead Safe Housing Rule. Exam tip: 1978 is the universal pre/post cutoff for lead paint disclosure, RRP, and HUD lead-safe practices.

5What is the recommended indoor relative humidity range for a healthy home?

A.10% to 25%

B.30% to 50%

C.55% to 75%

D.70% to 90%

Explanation: EPA, ASHRAE, and BPI HHP guidance recommend keeping indoor relative humidity between 30% and 50% (some sources extend to 60% in cooling seasons). Below 30% can cause respiratory irritation; above 60% promotes mold, dust mites, and condensation. Exam tip: 30-50% RH is the answer most often tested; values above 60% are an investigation trigger for moisture problems.

6Which BPI action level for ambient carbon monoxide indicates the home should be immediately evacuated and emergency responders contacted?

A.9 ppm

B.30 ppm

C.70 ppm

D.200 ppm

Explanation: BPI combustion safety guidance specifies 70 ppm ambient CO as the immediate evacuation threshold. 9 ppm is the EPA/ASHRAE indoor air quality goal; 30 ppm is the BPI investigation trigger; 35 ppm is OSHA's 8-hour worker exposure limit. Exam tip: Remember the ladder: 9 (IAQ goal), 30 (investigate source), 70 (evacuate and call 911).

7Which ASHRAE standard establishes minimum ventilation rates for acceptable indoor air quality in low-rise residential buildings?

A.ASHRAE 55

B.ASHRAE 62.1

C.ASHRAE 62.2

D.ASHRAE 90.1

Explanation: ASHRAE Standard 62.2 specifies minimum whole-house and local exhaust ventilation rates for single-family homes and low-rise multifamily dwellings. ASHRAE 62.1 applies to commercial and high-rise buildings, ASHRAE 55 covers thermal comfort, and 90.1 covers energy efficiency. Exam tip: For HHP, link residential ventilation to 62.2; the whole-house rate is roughly 7.5 cfm/person + 0.03 cfm per square foot.

8Integrated Pest Management (IPM) follows a hierarchy of control strategies. Which is the FIRST step?

A.Apply broad-spectrum pesticide spray

B.Inspect and identify the pest, then remove food, water, and shelter sources

C.Set up tamper-resistant bait stations on a routine schedule

D.Hire a fumigation contractor

Explanation: IPM emphasizes prevention first: inspect, identify the pest, and remove the conditions that allow it to thrive (food, water, harborage). Chemical controls are a last resort and use the least-toxic effective option (e.g., baits in tamper-resistant stations) rather than broadcast spraying. Exam tip: 'Inspect, identify, exclude, sanitize, then treat with least-toxic methods' is the IPM order BPI HHP expects.

9Which standard from the IICRC governs professional mold remediation procedures referenced in BPI HHP materials?

A.IICRC S100

B.IICRC S500

C.IICRC S520

D.IICRC S540

Explanation: IICRC S520 is the Standard for Professional Mold Remediation. S500 covers water damage restoration. HHP references S520 for proper containment, PPE, and removal practices when visible mold is found. Exam tip: Pair S500 with water/moisture remediation and S520 with mold remediation.

10Which household allergens are most strongly linked to childhood asthma triggers according to BPI HHP and CDC guidance?

A.Pollen, ragweed, and outdoor mold spores

B.Dust mites, cockroach allergen, mouse allergen, and pet dander

C.Cleaning fragrances and laundry detergents

D.Houseplant pollen and fish tank mold

Explanation: The strongest indoor asthma triggers identified in housing research are dust mites, cockroach and mouse allergens, pet dander (cat and dog), and mold. Outdoor allergens are seasonal contributors but not the primary indoor focus of HHP. Exam tip: HHP links the 'keep it pest-free' and 'keep it clean' principles directly to asthma triggers.

About the BPI HHP Exam

The BPI Healthy Housing Principles (HHP) Certificate of Knowledge validates foundational understanding of the eight principles of healthy housing (keep it clean, dry, pest-free, contaminant-free, safe, ventilated, comfortable, and maintained) and their relationship to occupant health. The 75-question online exam is self-paced with no proctor and a 1-year completion window. Passing earns 8 BPI CEUs and prepares candidates for the field-based BPI Healthy Home Evaluator (HHE) certification.

Frequently Asked Questions

What is the BPI Healthy Housing Principles (HHP) Certificate of Knowledge?

The HHP is BPI's foundational online certificate validating understanding of the eight 'keep it' principles of healthy housing. It has 75 multiple-choice questions, an 80% passing score (effective 2026), and is delivered online with no proctor. Passing earns 8 BPI CEUs.

How much does the BPI HHP exam cost in 2026?

The HHP online exam is $119 if paid by ACH, check, or debit card, or $122.57 if paid by credit card. The digital HHP Reference Guide is also $119; a printed version is $139+ shipping. There are no prerequisites or training requirements.

What is the passing score for the BPI HHP exam?

Effective January 1, 2026, the passing score is 80% (60 out of 75 questions). BPI raised it from 70% per the December 2025 HHP Scheme Handbook update. Older study materials may still reference 70%.

Is the BPI HHP exam proctored?

No. The HHP exam is delivered online with no proctor required. It is self-paced and you have one year from registration to complete it. This is the main delivery difference between a BPI 'Certificate of Knowledge' and a full BPI 'Certification' such as BA-P.

Does the BPI HHP certificate expire?

No. The HHP is a Certificate of Knowledge that does not require renewal. However, BPI certified professionals earn 8 CEUs by passing, which can be applied toward maintaining other BPI certifications such as BA-P, IDL, or HHE.

What is the difference between BPI HHP and BPI Healthy Home Evaluator (HHE)?

HHP is a knowledge-only online certificate covering the eight principles. HHE is a field-based BPI certification that requires both a written exam and a field exam, and authorizes the holder to perform commercial healthy home assessments. HHP is commonly used as preparation for HHE.
