1.1 Exam Format, Eligibility & Core Competencies
Key Takeaways
- The Certified Health Care Environmental Services Professional (CHESP) credential is administered by the American Hospital Association Certification Center (AHA-CC) in partnership with the Association for the Health Care Environment (AHE).
- Candidates qualify through three distinct eligibility pathways combining accredited education (Bachelor's, Associate's, or High School/GED) with 3 to 5 years of healthcare EVS experience, including 2 to 5 years in supervisory/management roles.
- The exam comprises 110 multiple-choice questions (100 scored operational items and 10 unscored pretest items) administered over a 120-minute (2-hour) testing session (~65 seconds per question).
- Passing standards are criterion-referenced and set by the Angoff method with statistical equating across forms; the AHA-CC does not publish a cut score, and the score report returns Pass/Fail plus a raw score for each of the six content areas.
- The June 2025 content outline lists six major content areas as fixed item counts: Regulatory Compliance (17), Planning/Design/Construction (8), EVS Operations and Infection Prevention (35), Waste Management (15), Financial Stewardship (15), and Administration (10) — 100 scored items total.
1.1 Exam Format, Eligibility & Core Competencies
The Certified Health Care Environmental Services Professional (CHESP) designation is the premier national credential for environmental services (EVS) leaders in healthcare. Administered by the American Hospital Association Certification Center (AHA-CC) in collaboration with the Association for the Health Care Environment (AHE)—a professional membership group of the American Hospital Association (AHA)—the CHESP credential validates executive-level mastery of healthcare cleaning science, infection prevention, regulatory compliance, fiscal stewardship, and facility management.
While frontline healthcare credentials like the Certified Health Care Environmental Services Technician (CHEST) and Certified Surgical Cleaning Technician (CSCT) evaluate tactical cleaning techniques and operative sanitation protocols, the CHESP credential is tailored specifically for managers, directors, system leaders, and operational consultants. It demonstrates an individual's capability to direct complex multidisciplinary operations, lead regulatory survey readiness, engineer infection prevention interventions, and optimize departmental financial performance.
1. Candidate Eligibility Pathways
To sit for the CHESP examination, the AHA-CC mandates that candidates fulfill specific educational and professional leadership prerequisites. Candidates must meet all criteria in one of three established pathways prior to submitting their examination application.

| Pathway 3 | High School Diploma / GED | 5 Years (60 months) | 5 Years (60 months) |
[!NOTE] How the handbook defines the two key terms. These footnotes decide eligibility, and candidates routinely misread them:
- "Environmental services experience" means "work experience in environmental services operation, infection prevention and waste and linen management." Housekeeping experience outside a health care context does not count.
- "Health care setting" explicitly "includes experience with a provider of environmental services or products to a health care facility (e.g., Consultants, Manufacturers, Vendors, Contract Services Providers, etc.)." A contract-services regional manager or a distributor's clinical specialist can therefore qualify without ever being a hospital employee.
The AHA-CC reserves the right — but is not obligated — to verify the accuracy of the information a candidate supplies.

+-----------------------------------------------------------------------------+
Key Testing Logistics:
- Item Distribution & Pretest Items: The examination consists of 110 multiple-choice questions. Of these, 100 are scored operational items that determine the candidate's final result, and 10 are unscored pretest items. Pretest items are evaluated psychometrically for statistical reliability before appearing on future forms. Pretest questions are indistinguishable from scored items; therefore, candidates must approach every question with equal diligence.
- Pacing & Time Management: With 120 minutes for 110 items, candidates have approximately 65.4 seconds per question. Rapid reading comprehension, prompt elimination of implausible distractors, and disciplined pacing are crucial.
- Delivery Modalities:
- Physical Test Center: Administered at authorized PSI test centers worldwide featuring secure testing stations, physical ID verification, and proctor supervision.
- Live Remote Proctoring (PSI Bridge): Candidates test from a private office or home environment utilizing a webcam, microphone, screen-sharing software, and real-time live proctor monitoring following a 360-degree environmental scan.
3. Psychometric Scoring & The Modified Angoff Method
The CHESP examination utilizes a criterion-referenced scoring methodology rather than a normative (curved) scoring system. This means candidates are evaluated strictly against an objective standard of minimum professional competence, independent of how other candidates perform during the same testing window.
+-----------------------------------------------------------------------------+
| CRITERION-REFERENCED STANDARD SETTING |
| |
| [SME Panel Review] -> Panel of practicing EVS directors & CHESPs |
| | |
| v |
| [Angoff Rating] -> SMEs estimate the probability that a "minimally |
| competent practitioner" answers each item correctly|
| | |
| v |
| [Cut-Score Derivation]-> Averaged item probabilities establish the raw |
| passing cut-score (number correct). The AHA-CC |
| does NOT publish this number. |
| | |
| v |
| [Form Equating] -> Statistical equating adjusts for minor variations |
| in difficulty across alternative exam forms |
+-----------------------------------------------------------------------------+
Under the Angoff Method, expert judges review each test item and estimate the probability that a minimally competent practitioner answers it correctly. Those ratings are averaged to determine the preliminary minimum passing score — that is, the number of correctly answered questions required to pass — which is then validated against actual candidate performance.
Two consequences follow directly from the handbook:
- There is no published passing percentage. The AHA-CC states that the passing standard "is applied consistently across all CHESP candidates who take the same form," but it never publishes the cut score. Any specific "you need 70%" figure circulating on prep sites is not an official AHA-CC number.
- Different forms can have different cut scores. When new forms are introduced, replacement items may make one form slightly easier or harder. The AHA-CC applies statistical equating so that the knowledge level required is equivalent across forms — which is precisely why a single fixed percentage cannot be published.
Your score report will show Pass or Fail plus a raw score for each of the six major content areas. Raw score means the number of questions answered correctly; individual item responses are never disclosed.
4. The 6 Core Blueprint Domains & Weight Breakdown
The CHESP Examination Content Outline (Copyright 2022 by the AHA Certification Center, rev. June 2025) is divided into six major content areas. Two details matter for planning your study:
- The AHA-CC publishes item counts, not percentages. The outline states a fixed number of examination items per content area — 17, 8, 35, 15, 15, and 10. Because exactly 100 items are scored, each item count happens to equal its percentage of the scored exam.
- Learn the official numbering. The handbook numbers the areas 1–6 in the sequence Regulatory Compliance → Planning, Design, and Construction → EVS Operations and Infection Prevention → Waste Management → Financial Stewardship → Administration. Your PSI score report returns a raw score for each of these six major categories, so knowing which number maps to which subject lets you read a failed report and target the retake.
The chapters in this guide are sequenced for teaching efficiency rather than in blueprint order; the mapping table below ties every chapter back to its official content area.
+-----------------------------------------------------------------------------+
| CHESP EXAM BLUEPRINT DOMAIN ALLOCATION |
| |
| [AREA 1] Regulatory Compliance -> 17 Scored Items (17%) |
| [AREA 2] Planning, Design, and Construction -> 8 Scored Items (8%) |
| [AREA 3] EVS Operations and Infection Prev. -> 35 Scored Items (35%) |
| [AREA 4] Waste Management -> 15 Scored Items (15%) |
| [AREA 5] Financial Stewardship -> 15 Scored Items (15%) |
| [AREA 6] Administration -> 10 Scored Items (10%) |
| |
| *Total Scored Items: 100 (Plus 10 Unscored Pretest Items = 110 Total) |
+-----------------------------------------------------------------------------+
Comprehensive Domain Competency Breakdown
| Official Content Area | Scored Items | Tasks the Outline Actually Lists | Where This Guide Teaches It |
|---|---|---|---|
| 1. Regulatory Compliance | 17 | Federal standards governing EVS work space, maintenance, and operations — ADA, RCRA, OSHA, DOT, EPA, CMS, EEOC, FMLA, HIPAA, 42 CFR 482.15 emergency preparedness, HCAHPS/TRISS scores; state and local health and environmental protection departments; CDC, AORN, APIC, and national accreditors (TJC, DNV); safety training coordination and documentation; institutional permits, licenses, and certificates; regulated medical waste handling documentation; annual risk/safety assessment (HVA, ICRA); culture of patient safety. | Chapter 6 (6.1–6.8) |
| 2. Planning, Design, and Construction | 8 | Working knowledge of furniture, wall coverings, finishes, fabrics, window treatments and curtains, floor coverings, and privacy/cubicle curtains; ICRA and PCRA risk assessment; institutional design standards; pre-purchase evaluation of cleaning maintenance recommendations; participation in PDC plans; infection control collaboration on construction; facility appearance plans; calculating EVS departmental costs for new buildings or expansion; interpreting manufacturer IFUs for medical equipment and the cleaning responsibility matrix. | Chapter 10 (10.1–10.5) |
| 3. EVS Operations and Infection Prevention | 35 | Cleaning requirements, chemicals, equipment, and labor products for each furnishing category; managing EVS program operations and resources; integrating infection control standards; quality management and accountability programs; monitoring performance indicators; area-specific cleaning requirements (patient rooms, common areas, OR, ICU, CCU, mental health, labor and delivery, specialty rooms, interventional radiology, pharmacy admixture/clean rooms, NICU/PICU, isolation); integrated pest management; construction clean-up; monitoring contracted services; rounding; chain of infection; PPE donning/doffing; technology integration (UV light, electrostatic sprayers, vaporizers, ozone); cleaning validation (ATP, DAZO); linen distribution and laundry management programs. | Chapters 2, 3, 4, 5 |
| 4. Waste Management | 15 | Waste management program goals, operating requirements, reporting procedures, manifests, and documentation; integrating infection control with waste operations; monitoring and evaluating regulated medical waste, hazardous waste, pharmaceutical waste, chemotherapeutic waste, pathological waste, recyclable materials, confidential document destruction, and universal waste. | Chapter 7 (7.1–7.6) |
| 5. Financial Stewardship | 15 | Budget line items; capital and expense budgets; life cycle costs; managing departmental budgets including FTE cost analysis by patient days and square footage; year-to-date expense monitoring; operating budgets and variance reports; financial impact of service level changes; capital equipment evaluation and requisitions; financial benchmarking analysis; maintaining FTE schedules against patient census; calculating cost savings and value improvement plans. | Chapter 8 (8.1–8.6) |
| 6. Administration | 10 | Departmental reporting and benchmarking; mission, vision, SMART goals, and scope of services; strategic planning; policies and procedures; quality control and CQI standards; leadership; human resources functions including position descriptions, performance appraisal instruments, disciplinary action, and employer relations; tiered training requirements; recognition and retention; committees; and engagement surveys with action plans; interdepartmental coordination and event planning; FTE staffing analysis; HCAHPS and customer expectations; service level agreements; safety, emergency, environmental, and hazardous materials management; scope of service and RFPs; equipment safety evaluation; committee participation; inventory and par levels; preventive maintenance; product evaluation; bids and contract negotiation; project tracking; training and competency assessment; inspection tours; public relations; code of ethics and corporate compliance; patient and internal customer surveys; Workers' Compensation and FMLA knowledge; bed tracking system response times. | Chapter 9 (9.1–9.8), 8.4–8.5 |
[!IMPORTANT] Blueprint Dominance: Content Area 3 (EVS Operations and Infection Prevention) alone carries 35 of the 100 scored items. Combined with Regulatory Compliance (17) and Waste Management (15), those three areas supply 67 of 100 scored items. Mastery of clinical microbiology, chemical disinfection kinetics, and regulatory standards is essential to passing — but note that Administration (10) and Financial Stewardship (15) together carry 25 items, so a candidate who studies only the cleaning science can still fail.
5. Cognitive Levels Tested
The Candidate Handbook states that CHESP Examination questions are "generally" categorized by three cognitive levels, and defines each one. The handbook does not publish a percentage split across those levels, so plan your preparation around all three rather than around an invented ratio.
+-----------------------------------------------------------------------------+
| COGNITIVE COMPLEXITY LEVELS |
| |
| [LEVEL 1: RECALL] |
| - "The ability to recall or recognize specific information." |
| - Example: Identifying the minimum contact time on an EPA master label. |
| |
| [LEVEL 2: APPLICATION] |
| - "The ability to comprehend, relate or apply knowledge to new or |
| changing situations." |
| - Example: Calculating productive FTE requirements given square footage. |
| |
| [LEVEL 3: ANALYSIS] |
| - "The ability to analyze and synthesize information, determine solutions |
| and/or evaluate the usefulness of a solution." |
| - Example: Troubleshooting an environmental outbreak of Candida auris |
| spanning three clinical units under simultaneous staffing shortages. |
| |
| NOTE: The AHA-CC names these three levels but does NOT publish how many |
| items fall into each. Treat any percentage split you see elsewhere as |
| unverified. Prepare as though most items are application and analysis. |
+-----------------------------------------------------------------------------+
6. Certification Lifecycle & Recertification Requirements
Upon passing the examination, the CHESP credential is awarded for a three-year (3-year) certification cycle. To maintain active certification, the AHA-CC requires credential holders to demonstrate ongoing professional growth.
+-----------------------------------------------------------------------------+
| CHESP 3-YEAR RENEWAL LIFECYCLE |
| |
| Option A: Continuing Professional Education (CEUs) |
| +-------------------------------------------------------------------+ |
| | - Accumulate a minimum of 45 Contact Hours / CEUs over 3 Years | |
| | - Each activity is reported with ONE Content Code drawn from the | |
| | Examination Content Outline categories, in 30-minute increments | |
| | - Some activity TYPES carry a 3-year maximum-hour cap | |
| | - Submit renewal application and maintenance fee to AHA-CC | |
| +-------------------------------------------------------------------+ |
| -- OR -- |
| Option B: Re-examination |
| +-------------------------------------------------------------------+ |
| | - Retake and pass the CHESP examination NO MORE THAN ONE YEAR | |
| | prior to the credential expiration date (usual exam fees apply; | |
| | no separate renewal application fee is required) | |
| +-------------------------------------------------------------------+ |
+-----------------------------------------------------------------------------+
Administrative Rules That Cost Candidates Money
| Situation | Handbook Rule |
|---|---|
| Rescheduling | Application fees are nonrefundable and nontransferable, but a candidate who cannot test may reschedule through PSI. The exam must be rescheduled within 90 days of the originally scheduled date. Missing that window forfeits the application and all fees. |
| Arriving late | Report to the PSI test center 30 minutes before the scheduled appointment. A candidate who arrives more than 15 minutes after the scheduled testing time is not admitted. |
| Failing | There is no limit on the number of attempts, but every retake requires a new application and the full examination fee ($275 member / $425 nonmember). |
| Late renewal | Renewals may be submitted up to 30 days past the expiration date for an additional nonrefundable $50 fee. |
| Lapsed certification | A certificant who fails to renew may no longer use the CHESP credential and must retake and pass the examination to regain it. |
| Appeals | Written appeals go to the AHA Certification Center with a $100 fee, refunded if the appeal is deemed justified. |
The Eight Eligible Activity Types (and Their Caps)
AHE's About Continuing Professional Education instructions define a contact hour as 50–60 minutes of educational experience, require every activity to run at least 30 minutes and be reported in 30-minute increments, and assign every activity both a Content Code and a Type Code. Only these eight types earn credit:
| Type Code | Eligible Activity | Conversion / Credit Rule | 3-Year Maximum |
|---|---|---|---|
| 1 | Educational program — lecture, workshop, educational session, or case presentation from a professional healthcare association, a healthcare facility or provider of services to one, or an industry-recognized provider | Multiple participations in the same course count only once | No limit |
| 2 | Academic coursework (in person or online, accredited college/university) | 1 semester credit = 15 contact hours; 1 quarter credit = 10 | 15 contact hours |
| 3 | Self-study — audio conference or online educational program; the provider must award contact hours | Online academic coursework is Type 2, not Type 3 | No limit |
| 4 | Professional speaking/teaching at a national, regional, state, or local association program or meeting | Credit may be declared for twice the length of the program or speech | 15 contact hours |
| 5 | Academic teaching at an accredited college/university | 1 semester credit = 15 contact hours; 1 quarter credit = 10 | 15 contact hours |
| 6 | Test item writing for an AHA Examination | 0.5 contact hours per accepted item | 15 contact hours |
| 7 | AHA-CC Self-Assessment Examination | Completion earns 5 contact hours | 15 contact hours |
| 8 | Authoring/publishing a book chapter, or at least two articles in journals with documented circulation above 1,000 readers | Earns 5 contact hours; must be published within the cycle, relate to the outline, and appear outside your own facility | 15 contact hours |
[!WARNING] Two traps in the renewal rules. First, only Types 1 and 3 are uncapped — every other route stops at 15 contact hours over the three-year cycle, so you cannot reach 45 hours by teaching or publishing alone. Second, committee service, advisory-board membership, and ordinary job duties are not eligible activity types at all, however professionally valuable they are. AHE also notes that it does not track credits on your behalf; documentation for each activity (certificate of attendance, transcript, program copy, or letter) is the certificant's responsibility.
