What the CEICC Credential Actually Is
The Council-certified Environmental Infection Control Consultant (CEICC) credential is awarded by the American Council for Accredited Certification (ACAC). It targets professionals who manage the environmental side of infection prevention, particularly in healthcare facilities where construction, demolition, and renovation can put vulnerable patients at risk. If you want a plain-language primer first, see What Is CEICC Certification? or What Does CEICC Stand For?.
Because several unrelated credentials share similar acronyms, it is worth being precise: everything in this article concerns the ACAC credential and nothing else. The exam is delivered through the testing provider Kryterion, and the standards behind it come from ACAC's candidate handbook rather than from any other certifying organization.
Eligibility Pathways and Documentation
ACAC offers three routes to qualify, each trading education for field experience. The structure rewards hands-on practice: the less formal education you have, the more documented years you need.
| Education Background | Qualifying Credits | Documented Field Experience |
|---|---|---|
| Relevant four-year degree | Equivalent 30 qualifying semester credits | Four years |
| Relevant two-year degree | Equivalent 15 qualifying credits | Six years |
| High-school diploma or GED | None specified | Eight years |
For a deeper walkthrough of how these tiers work in practice, read CEICC Requirements: Eligibility, Prerequisites & How to Qualify.
The four project sheets
Every applicant must submit four distinct project sheets, along with verification of the work described. "Distinct" matters: reviewers expect four separate projects rather than one project split into four write-ups. Start collecting project details, such as scope, containment measures used, your specific role, and a supervisor or client who can verify the work, well before you open the application.
No mandatory training course
ACAC does not require a specific training course before you sit the exam. An optional study guide exists, but candidates can prepare through experience and self-study. If you are weighing formal instruction, see our overview of CEICC training options.
Exam Format and Delivery
- Questions: 120 multiple-choice items, each with at least four answer choices
- Time limit: three hours
- Materials: closed book
- Passing threshold: 75%, set using the Modified Angoff method
- Delivery: computer-based at a test center, or online with secure video proctoring
- Results: available immediately
The Modified Angoff method means a panel of subject-matter experts judged how a minimally competent candidate would perform on each question, and the cut score reflects that judgment. The 75% bar is a fixed standard, not a curve against other candidates. For more on what that threshold implies, see CEICC Passing Score: Exactly What You Need to Pass.
Three hours for 120 questions averages out to 90 seconds per item. That is comfortable for recall questions but tighter for scenario items that ask you to choose the correct containment, barrier, or notification step from several plausible options. Expect questions that test judgment in applied situations, not just vocabulary.

The Four Competency Areas
The four headings below come from the handbook's Required Skills competencies and are corroborated by the optional study guide. ACAC does not publish weights for them, and the headings do not establish that exam coverage is exhaustive, so treat them as a minimum framework and study the surrounding practice area. For a full breakdown, see CEICC Exam Domains: Complete Guide to All 4 Content Areas.
Domain 1: Infectious Diseases and Their Modes of Transmission in the Healthcare Setting
This is the biological foundation. Environmental controls only make sense if you understand what you are controlling.
- Airborne, droplet, and contact transmission, and how each drives a different engineering or barrier response
- Environmental reservoirs and the organisms of particular concern around construction dust and water systems
- Which patient populations are most vulnerable to environmental pathogens
- How OSHA's bloodborne pathogens standard (29 CFR 1910.1030) frames exposure
Domain 2: Principles of Infection Control During Construction, Demolition and Renovation
For most candidates, this is the signature domain of the credential. It is where environmental infection control becomes concrete.
- Containment strategies, barriers, and pressure relationships between work zones and occupied areas
- Ventilation and air-handling considerations, including the standards ACAC lists in its references
- Controlling dust, debris, and water intrusion, and managing traffic and waste paths
- Matching the level of precaution to the scope of work and the risk of the affected patient area
Domain 3: Infection Control Project Management
Knowing the controls is not enough; the consultant must organize people and processes so the controls actually happen.
- Pre-project risk assessment and planning with facility stakeholders
- Communication among contractors, facility staff, and infection prevention teams
- Documentation, monitoring, and verification during the project
- Responding when a barrier fails or conditions change mid-project
Domain 4: Effective Infection Control Practices
This area covers the day-to-day practices that protect workers, patients, and visitors.
- Personal protective equipment and respiratory protection, including NIOSH respirator selection logic
- Hygiene, cleaning, and disinfection practices relevant to the environment
- Worker safety and the ethical obligations that come with the consultant role
- Professional conduct under the ACAC Code of Conduct
Key Takeaway
Domains 2 and 3 will feel most natural if you have run renovation projects in occupied healthcare facilities. If your background is clinical, plan extra time on containment, pressure, and ventilation concepts; if it is construction, spend extra time on transmission science.
Fees and Registration Mechanics
| Item | USD Fee |
|---|---|
| Examination fee | $100 |
| Certification fee | $400 |
| Initial total | $500 |
| Exam retake | $100 |
| Renewal | $400 |
The structure separates the exam from the credential itself: the $100 examination fee covers the test, while the $400 certification fee covers the award. A failed attempt therefore costs a $100 retake, not another $500. For budgeting beyond the fee schedule, see CEICC Certification Cost: Complete Pricing Breakdown.
Sequence matters in practice. You assemble your education evidence, four project sheets, and verification, then move through ACAC's review, and only then take the exam. Because your application clock may be as short as 90 days or as long as six months, avoid starting the process until your project documentation is nearly finished.
Reference Editions to Study From
ACAC's materials point to specific source documents, and using the right editions matters when questions hinge on particular language:
- CDC environmental infection control guideline (2003, updated 2019)
- OSHA 29 CFR 1910.1030, the bloodborne pathogens standard
- NIOSH Respirator Selection Logic (2004)
- ACAC Code of Conduct
- ASHRAE 170-2008, listed in the handbook
Our CEICC study guide and one-page CEICC cheat sheet are built around these source documents.
Sequencing Your Preparation
Rather than a generic study calendar, order your preparation by how the domains build on each other. This eight-week sketch assumes you already meet eligibility and are working on exam readiness; adjust it to your background.
Domain 1 foundations
- Transmission routes and environmental reservoirs, using the CDC guideline
- Map each route to the control it triggers
Domain 2 depth
- Containment, pressure relationships, and ventilation, including ASHRAE 170-2008
- Work through renovation scenarios by risk level
Domain 3 project management
- Risk assessment, communication, documentation, and failure response
Domain 4 practices
- Respirator selection logic, PPE, OSHA bloodborne pathogens, Code of Conduct
Timed practice
- Full 120-question sets in three hours using the CEICC practice tests
- Review every miss against the source document
The point of putting Domain 2 in the longest block is that it is the area where scenario questions can offer several plausible-sounding answers. Practicing under timed conditions on our practice exam platform helps you build the 90-seconds-per-question pacing the real test requires.
Validity and Renewal
CEICC certification is valid for two years. According to the recertification procedures, renewal requires 40 renewal credits (RCs), made up of 10 for continued field activity and 30 hours of professional development. ACAC may audit your records, so keep certificates, attendance logs, and project documentation organized from the start of each cycle. Renewal costs $400.
Who Uses This Credential
The credential fits professionals who sit between clinical infection prevention and the built environment. Typical settings include hospitals and health systems, construction and renovation firms working in healthcare facilities, environmental and safety consulting practices, and facilities-management teams responsible for maintenance in patient-care areas. Roles that tend to value it include infection control consultants, facility project managers, and safety professionals who oversee work near vulnerable patients.
ACAC's December 31, 2025 activity report lists 25 current CEICC certifications. That is a count of current holders, not exam volume, but it does signal a small, specialized credential rather than a mass-market one. That scarcity can make the designation distinctive in a niche field, though it also means public salary data is limited; read our qualitative takes in the CEICC salary guide, CEICC jobs overview, and analysis of whether CEICC is worth it.
A note on pass-rate data
ACAC's published pass ratios show 3 passes from 3 examinations in 2024 and 1 from 1 in 2023, both 100%. These figures include retakes and state-license-only examinations, and the cohorts are tiny, so they are not first-attempt success estimates. They say little about how difficult your own attempt will be. See CEICC Pass Rate: What the Data Shows for context on interpreting them.
