- The CEICRA passing threshold is 70%, set by the American Council for Accredited Certification using the Modified Angoff method.
- The exam has 50 closed-book multiple-choice questions with at least four answer choices, and you get two hours.
- Initial cost is $400 total: a $100 examination fee plus a $300 certification fee; a retake costs $100.
- The handbook's three required-skill headings are unweighted, so prepare evenly across all three domains.
The 70% Threshold in Plain Terms
If you are preparing for the Council-certified Environmental Infection Control Remediation Assistant credential, the number that governs your outcome is simple: 70%. That is the passing threshold published for the CEICRA examination, which is administered under the American Council for Accredited Certification (ACAC) with Kryterion as the testing provider.
This article focuses narrowly on that cut score: how it was determined, what it implies about your preparation, and how the surrounding mechanics (fees, retakes, deadlines) interact with it. If you want the broader picture of how demanding the test is, our guide on how hard the CEICRA exam is covers difficulty in more depth, and the CEICRA pass rate article discusses what is and is not publicly known about outcomes.
How Modified Angoff Sets the Bar
ACAC states that the 70% threshold for CEICRA is set using the Modified Angoff method. This matters because it tells you the passing standard is not an arbitrary round number and not a "curve" against other candidates.
What the method does
In an Angoff-style standard-setting process, subject-matter experts review each exam question and estimate the probability that a minimally competent candidate would answer it correctly. Those judgments are combined into a recommended cut score. The "modified" variant typically adds discussion and review rounds so panelists can reconcile differences.
What this means for you
- You are measured against a competence standard, not other test-takers. Your result does not depend on how strong the rest of the candidate pool is on exam day.
- The target is "minimally competent," not "expert." The standard describes someone who can safely do the job, which should shape how you study: depth on core principles beats trivia.
- Everyone faces the same bar. There is no published adjustment by testing window, location, or delivery mode.
We deliberately avoid quoting any scaled-score ranges or percentile claims, because ACAC's published materials describe the passing standard as a 70% threshold and nothing more granular than that.
Exam Format Behind the Score
A percentage threshold only means something in the context of the test structure. Here is how the CEICRA exam is built, according to ACAC's published information.
| Feature | CEICRA Exam Detail |
|---|---|
| Certifying body | American Council for Accredited Certification (ACAC) |
| Testing provider | Kryterion |
| Question count | 50 multiple-choice questions |
| Answer choices | At least four per question |
| Time allowed | Two hours |
| Reference materials | Closed book |
| Passing threshold | 70%, set using Modified Angoff |
| Delivery | Computer-based test center or secure online video proctoring; preauthorized instructor proctoring also available under ACAC's vocational-program policy |
Two details deserve emphasis. First, the exam is closed book, so recall of definitions, thresholds, and procedures is essential. Second, two hours for 50 questions is a comfortable pace, which means time pressure is rarely your main enemy. Accuracy and careful reading are.
What 70% Means in Practice
On a 50-question exam, a 70% threshold translates to answering 35 questions correctly. That is simple arithmetic from the published figures: 50 × 0.70 = 35. Put differently, you can miss up to 15 questions and still reach the threshold.
Setting a personal target
- Minimum goal: consistently clear 70% on timed practice sets that mimic the closed-book, four-plus-choice format.
- Safer goal: build a buffer in practice so that an off day or a handful of oddly worded items still leaves you above the line.
- Watch for lopsided scores: because the exam is a single combined score, a weak domain can be offset by a strong one, but relying on that is risky when you cannot predict question distribution.

Where Your Points Come From: The Three Domains
The CEICRA handbook lists three Required Skills competencies. They are unweighted in the published materials, and they do not establish exhaustive exam coverage. That means you cannot reliably assume one domain is "worth" more points than another. The practical response is balanced preparation. Our complete guide to all three CEICRA content areas expands on each one.
Domain 1: Infectious Diseases and Their Modes of Transmission in the Healthcare Setting
This domain covers the "why" behind every control measure. If you understand how pathogens move, the rest of the exam becomes more logical.
- Common routes of transmission and which environments favor them
- Why certain patient populations are especially vulnerable
- How environmental conditions in healthcare facilities contribute to risk
- Waterborne and airborne concerns that matter during remediation work
Domain 2: Principles of Infection Control During Construction, Demolition and Renovation
This is the most role-specific domain for remediation assistants. Expect scenario-style thinking about how building work can disturb dust, moisture, and contamination near vulnerable patients.
- How construction activity can release contaminants into occupied care areas
- Barrier, containment, and pressure-related concepts used to protect adjacent spaces
- Planning and risk-awareness steps before work begins
- Cleanup, debris handling, and verifying that an area is safe to return to use
Domain 3: Effective Infection Control Practices
This domain is about the day-to-day behaviors and protocols that keep controls working. It is where professional conduct and routine discipline meet technical knowledge.
- Hygiene, protective equipment, and cleaning practices
- Environmental surface and equipment handling principles
- Communication and compliance expectations on the job
- Professional ethics, including familiarity with the ACAC Code of Conduct
Because a single 70% threshold applies to the whole exam, think of the three domains as one connected knowledge base rather than three separate hurdles. Candidates who study them in isolation often struggle when a question blends, for example, a transmission concept with a construction-phase control.
Reference Material Worth Your Hours
ACAC's embedded study guide points candidates to two specific references: the ACAC Code of Conduct and the CDC Guidelines for Environmental Infection Control in Health-Care Facilities (2003, updated 2019). The guide highlights selected pages and Tables 1, 3, 6, 8, 9 and 10 of the CDC document.
Key Takeaway
Start with the highlighted CDC tables. Since the exam is closed book and you need roughly 35 correct answers, familiarity with the tables ACAC singled out is one of the highest-return uses of your time. Read them for meaning, not just memorization, so you can apply them to scenario questions.
No training course is mandatory for CEICRA, which puts the responsibility for structured preparation squarely on you. If you want a step-by-step plan built around these sources, our CEICRA study guide walks through a first-attempt approach, and the CEICRA training overview discusses optional ways to build skills.
Fees, Retakes, and the Cost of Missing the Mark
Your passing score is tied directly to money, because falling short means paying again. ACAC's published fees are:
| Fee | Amount (USD) |
|---|---|
| Examination fee | $100 |
| Certification fee | $300 |
| Initial total | $400 |
| Retake | $100 |
| Renewal | $300 |
The structure is worth understanding. The $400 initial total combines the exam and certification components. A retake costs $100, which equals the examination fee, so a miss is painful but not catastrophic. Still, between the retake fee and the delay, preparing to pass the first time is clearly the efficient path. Our CEICRA certification cost breakdown covers the full pricing picture, and the ROI analysis helps you weigh the investment against career goals.
Timeline and Deadline Pitfalls
Before you ever sit for the exam, you must clear eligibility steps: attest to current employment in infection control, complete the online application, and finish the required email verifications. The current application expressly exempts CEICRA from project sheets. Our CEICRA requirements article details these prerequisites.
Award follows both the examination and a certification-board review, so passing the exam is necessary but is not the final step. Plan for that review stage when thinking about when you will actually hold the credential. For testing windows and scheduling logistics, see our guide to CEICRA exam dates.
Scheduling Your Prep Around the Cut Score
Because the three domains are unweighted and the passing mark is a single 70% threshold, a balanced, build-up-then-test sequence makes sense. Here is one way to map the domains to a short timeline.
Transmission foundations
- Work through Domain 1 first, since it explains why later controls exist
- Read the CDC document's highlighted pages and Tables 1 and 3
Construction, demolition and renovation controls
- Study Domain 2 with the remaining highlighted tables, including Tables 6, 8, 9 and 10
- Practice applying barrier and containment ideas to scenarios
Practices, conduct, and full-length practice
- Cover Domain 3 and review the ACAC Code of Conduct
- Take a timed 50-question practice set and aim comfortably above 35 correct
Adjust the pace to your experience. Someone already working daily in healthcare construction oversight may compress Domain 2, while a newer professional may extend it. When you are ready to test yourself, use the CEICRA practice tests to check whether you are clearing the line with room to spare.
After You Pass: Certification and Renewal
Passing is the gateway, not the finish line. The credential is valid for two years. The handbook calls for 40 recertification credits (RCs), and current central procedures allocate 10 RCs for continued field activity plus 30 hours of professional development, with records subject to audit. Renewal carries a $300 fee.
If your goal is career movement, our articles on CEICRA jobs and the CEICRA salary guide explain how the credential fits into employment, and the CEICRA certification overview ties the whole process together. For a fresh start on the basics, What Is CEICRA? is a good primer. You can also return to the main CEICRA Exam Prep practice site any time to keep sharpening your recall.
