The Passing Score, in Plain Numbers
If you're preparing for the Airport Certified Employee - Communications Center Operations exam, the number that matters most is simple: 70%. Out of 100 multiple-choice questions, you need 70 correct answers to earn the ACE-CCO designation from the American Association of Airport Executives (AAAE). There's no partial credit, no curve, and no separate cutoff for individual content areas - it's a single overall score based on the total exam.
That flat, transparent scoring model is good news for candidates. You don't have to guess which topics are "weighted" more heavily or worry about failing one section while passing another. Every question counts the same, whether it's about call classification or NIMS coordination. For a broader breakdown of how this compares to other credentialing exams, see our ACE-CCO Pass Rate 2026: What the Data Shows article.
How the ACE-CCO Exam Is Structured
Understanding the format helps you understand what "passing" actually demands. The exam consists of 100 multiple-choice questions, and you have 120 minutes to complete it - roughly 72 seconds per question if you spread your time evenly. AAAE administers the exam through TopClass with recorded remote proctoring, meaning you'll need a computer, a working webcam, a microphone, and a government-issued photo ID on hand before you start.
The exam is closed-book. There's no reference sheet, no open tab with your study modules, and no notes pulled from your communications center's SOP binder. Everything you need to hit 70 correct answers has to already be in your head when the clock starts. If you're unsure how this format compares to other credentialing exams you may have taken, our How Hard Is the ACE-CCO Exam? Complete Difficulty Guide 2026 breaks down the difficulty in more detail.
Key Takeaway
Because the exam is closed-book and time-boxed, passing isn't just about knowing the material - it's about recalling it quickly under a strict 120-minute limit. Build recall speed into your prep, not just comprehension.
What Scoring 70% Actually Requires
It's tempting to treat "70%" as a low bar, but in practice it means you can afford to miss no more than 30 questions across the entire exam - and those misses can come from anywhere in the content. A weak spot in one area (say, CAD and telephony systems) isn't automatically offset by strength in another (like professionalism and confidentiality), because the pass/fail line is calculated on the total, not by domain.
This is why candidates who treat the exam as a checklist - "I know radios, I know CCTV, I'll skim the legal liability stuff" - sometimes come up short. A handful of shaky topics scattered across the content areas can quietly add up to more than 30 missed questions. The safer approach is even, deliberate coverage of every topic AAAE lists in its official review-course outline, which we map out fully in the ACE-CCO Exam Domains 2026: Complete Guide to All 0 Content Areas.
Content Areas You Must Master to Clear 70
The official AAAE review course for the Airport Communications Center Operations track covers a specific, named set of topics. These aren't abstract "soft skills" - they map directly to what a communications specialist or dispatcher actually does during a shift in an airport communications hub. Treat each one as a study unit, because a question could come from any of them.
Center Roles and Stakeholder Coordination
Understanding who does what inside a communications center and how the center interfaces with airport operations, law enforcement, fire/rescue, and airline partners.
- Know the chain of communication between the center and field units
Professionalism, Confidentiality, and Stress Management
Handling sensitive information appropriately and maintaining composure and judgment during high-pressure or emotionally charged calls.
- Recognize confidentiality obligations tied to airport operations data
Legal Liability and Active Listening
Understanding the legal exposure tied to dispatch decisions and documentation, paired with the listening techniques that reduce miscommunication on live calls.
- Focus on how documentation practices reduce liability risk
CAD, Telephony, Radios, CCTV, and Alarms
The technical backbone of the job - computer-aided dispatch systems, phone systems, radio protocols, camera monitoring, and alarm response procedures.
- Expect scenario questions testing correct tool/procedure selection
Call Classification, Prioritization, and Difficult Callers
Sorting incoming calls by urgency and type, then applying the right response - including techniques for managing hostile, panicked, or unclear callers.
- Practice ranking multiple simultaneous scenarios by priority
NIMS, Irregular Operations, and Emergency Coordination
The National Incident Management System framework as it applies to airport emergencies, plus how communications centers coordinate during irregular operations events.
- Memorize the basic NIMS structure and its application at airports
Cybersecurity Awareness
Baseline awareness of cyber risks relevant to communications center systems and data handling.
- Know general best practices rather than deep technical detail

Registration, Fees, and Retake Costs
Passing the exam on your first attempt matters financially, not just for your timeline. Standard enrollment is $555 for both members and non-members, or $395 at the student rate if you submit a current course schedule at registration. That fee includes electronic study modules and one exam attempt - review courses and printed materials are separate purchases.
If you don't hit 70 correct answers on your first try, the retake fee is $75. That's a modest cost compared to full re-enrollment, but it's still money and time you'd rather not spend twice. AAAE also requires that you take the exam within 26 months of enrollling, so there's a real deadline attached to your preparation window - not an open-ended runway. For the complete fee breakdown, see ACE-CCO Certification Cost 2026: Complete Pricing Breakdown.
| Item | Cost | What It Covers |
|---|---|---|
| Standard enrollment | $555 | Electronic study modules + one exam attempt |
| Student rate enrollment | $395 | Same as above, requires current course schedule |
| Failed-exam retake | $75 | One additional exam attempt |
| Blank Slate flashcard app (optional) | $150 | 90 days of access to official flashcards |
Key Takeaway
Your enrollment fee buys exactly one exam attempt. Missing 70 correct answers means paying an additional $75 to try again - budget your study time accordingly.
A Domain-Aware Prep Timeline
AAAE recommends at least 90 days of preparation before sitting for the ACE-CCO exam. That's not a random suggestion - it reflects the breadth of the content areas above, most of which involve procedural knowledge that's hard to absorb by cramming. A domain-aware timeline spreads your effort across all the review-course topics rather than letting your strongest area eat all your study time.
Foundations
- Study center roles, stakeholder coordination, and professionalism/confidentiality
- Skim the full official topic list so nothing is a surprise later
Technical Systems
- Deep-dive CAD, telephony, radios, CCTV, and alarms
- Practice scenario questions that test correct tool selection under pressure
Call Handling and Emergency Response
- Work through call classification, prioritization, and difficult-caller techniques
- Study NIMS, irregular operations, and emergency coordination together since they overlap
Review and Timed Practice
- Add legal liability, active listening, and cybersecurity awareness review
- Run full-length timed practice sets to build 120-minute stamina
Notice this timeline uses spaced review rather than one long marathon session - the point isn't a study methodology gimmick, it's matching your review calendar to the specific content areas listed in AAAE's official outline.

Test-Day Logistics That Protect Your Score
A surprising number of candidates lose points not because they didn't know the material, but because test-day logistics ate into their focus or their time. Since the exam is closed-book and remotely proctored, a few practical steps protect the score you've actually earned through study:
- Confirm your computer, webcam, and microphone work well before your scheduled start - TopClass requires all three for remote proctoring.
- Have your government-issued photo ID ready and easily accessible; delays here eat into your 120-minute window in some proctoring setups.
- Clear your desk completely - closed-book means no notes, no reference sheets, no secondary monitor with study material open.
- Pace yourself against the 100-question, 120-minute format so you're not rushing the final stretch of questions.
None of this replaces content knowledge, but it removes avoidable friction between what you know and what you're able to demonstrate on exam day. For eligibility details before you even get to this stage, check ACE-CCO Requirements 2026: Eligibility, Prerequisites & How to Qualify, and for exact scheduling windows see ACE-CCO Exam Dates 2026: Testing Windows, Deadlines & Scheduling.
It's also worth remembering why this credential exists in the first place. Airports and their communications hubs - not general 911 dispatch centers - are the primary hiring ground for ACE-CCO holders. If you're weighing whether the investment of $555 (or $395 as a student) and 90+ days of study is worth it for your career path, our Is the ACE-CCO Certification Worth It? Complete ROI Analysis 2026 article and ACE-CCO Salary Guide 2026: Complete Earnings Analysis walk through that decision in more depth. You can also browse current openings referencing the credential in our ACE-CCO Jobs roundup.
Repetition against realistic, scenario-style questions is one of the most effective ways to close the gap between "I've read the material" and "I can hit 70 correct answers in 120 minutes." Running practice sets on our practice exam platform before you sit for the real thing lets you find weak content areas while there's still time to fix them, rather than discovering them mid-exam.
