- ACCA has not published a historical EPIC pass rate - the program is being rewritten for Fall 2026.
- Candidates must clear two separate hurdles: an 80% knowledge assessment and a live presentation review.
- Content spans Manuals D, J, H, P, S, T, Manual 4, and TT-102 - breadth, not just depth, drives outcomes.
- Certification is valid for five years, so failing once has real cost in time and rescheduling.
The Pass Rate Reality: No Published Number Yet
If you searched for "EPIC pass rate 2026" hoping for a clean percentage, here's the honest answer: ACCA has not released one. The Education Professional Instructor Certification is being updated and rewritten ahead of a planned Fall 2026 release, which means there is no long-running public dataset of pass/fail outcomes to analyze the way you might for a mature national exam. Any site quoting a specific pass-rate percentage for EPIC right now is guessing, not reporting.
What we can do - and what this article does - is look at the actual structure of the credential as ACCA has announced it and reason through where candidates are most likely to lose points, stall out, or need a second attempt. That structural analysis is more useful than a fabricated number anyway, because it tells you where to put your preparation effort, not just how nervous to be.
Two Separate Hurdles, Two Ways to Fail
Most credentialing exams have a single failure point: you either score above the cutline or you don't. EPIC is different because it's a two-stage process, and each stage has its own pass/fail logic.
- Stage one - online knowledge assessment. Administered through ACCA's online testing portal, this requires a minimum score of 80% to advance. That's a high bar compared to many credentialing exams that set cutlines closer to 70%.
- Stage two - virtual presentation. Candidates who clear the knowledge assessment must then deliver a virtual presentation of assigned HVAC content to a panel of students and evaluators. This isn't a written test - it's a live demonstration of teaching ability.
Because both stages must be cleared, your effective "pass rate" risk is really the product of two separate risks: the chance you miss the 80% cutline, and the chance your presentation doesn't satisfy the evaluator panel. Preparation that only addresses one of these - usually the knowledge side, because it feels more like traditional studying - leaves a real gap. For a deeper look at how the score threshold itself is calculated and interpreted, read EPIC Passing Score 2026: Exactly What You Need to Pass.
Key Takeaway
Treat EPIC as two exams stacked on top of each other. Budget separate preparation time for content mastery and for presentation delivery - don't assume passing the knowledge portion means you're ready for the panel.
Inside the 80% Knowledge Assessment
The 80% threshold is unforgiving in a technical field where content spans multiple ACCA manuals. Unlike a broad HVAC technician exam that might sample lightly across many topics, EPIC's knowledge assessment is built for people who already teach this material - so the expectation is fluency, not familiarity.
Because the assessment is delivered through an online portal rather than a paper test center, candidates should expect a format built around discrete, scenario-anchored questions tied to specific manual content rather than abstract theory. Instructors who have taught load calculation or duct design for years sometimes underestimate this stage because they know the material conversationally but haven't been tested on the precise figures, formulas, and procedural sequences ACCA's manuals define.
A structured review - not a refresher skim - is the difference-maker here. The EPIC Study Guide 2026: How to Pass on Your First Attempt lays out a manual-by-manual review sequence that maps directly onto this assessment structure.
The Virtual Presentation: Where Candidates Actually Struggle
If there's a single stage most likely to produce unexpected outcomes, it's the presentation. Passing a knowledge assessment tests what you know. Presenting assigned HVAC content live to a panel of students and evaluators tests whether you can transmit that knowledge clearly, under time pressure, in front of an audience that includes both learners and graders simultaneously.
This is a fundamentally different skill from technical recall, and it's the part of EPIC that most resembles an actual teaching demonstration rather than a certification exam. Evaluators are assessing:
- Clarity of explanation for the assigned content area
- Ability to field questions from students in real time
- Pacing and structure of the presentation within its allotted format
- Command of the underlying manual content being presented
Experienced instructors generally have an advantage here, since the program assumes fundamental subject knowledge and communication ability as a baseline. But even veteran instructors benefit from rehearsing a presentation specifically in the assigned-content format EPIC uses, rather than relying on their usual classroom style, which may not fit the panel's time constraints or evaluation criteria.
Content Coverage That Drives Outcomes
ACCA lists a specific set of manuals as the subject coverage for EPIC: Manual D, Manual J, Manual H, Manual P, Manual S, Manual T, Manual 4, and TT-102. This breadth is itself a factor in pass/fail outcomes - candidates who are deeply expert in one or two manuals but rusty on others are exposed on both the knowledge assessment and the presentation, since the assigned presentation topic could come from any covered area.
Manual D - Residential Duct Systems
Candidates must be able to explain duct sizing methodology and friction rate concepts clearly enough to teach them, not just apply them.
- Static pressure and airflow relationships
- Duct sizing charts and their practical application
Manual J - Residential Load Calculations
Widely considered the anchor manual of residential HVAC design; expect deep coverage here.
- Heat gain/loss calculation inputs
- How load results feed into equipment selection
Manual S - Equipment Selection
Connects load calculation output to real equipment sizing decisions - a frequent source of exam scenario questions.
- Matching equipment capacity to calculated loads
- Sensible vs. latent capacity tradeoffs
Manual H, P, T, Manual 4, and TT-102
These round out the coverage list and are easy to under-prepare for since they receive less daily classroom emphasis than Manual J.
- Refrigerant piping and system design concepts (Manual T)
- Duct testing and technical procedures referenced in TT-102
For a complete breakdown of how these manuals map onto the exam's tested content areas, see EPIC Exam Domains 2026: Complete Guide to All Content Areas.
Who Tends to Pass - and Who Doesn't
Because EPIC is explicitly designed for experienced HVACR vocational instructors, the candidate pool isn't a general audience - it's already a filtered group of people who teach this material for a living. That changes how you should think about "pass rate" risk: you're not competing against novices, you're being measured against a peer group that already assumes baseline fluency.
Instructors most likely to pass on the first attempt tend to share a few traits:
- They actively teach multiple manuals in the coverage list, not just one or two
- They've reviewed formulas and procedural details recently, not just conceptually
- They've rehearsed a timed presentation format before test day
- They understand the eligibility and registration mechanics well in advance, so nothing about logistics is a surprise on exam day
If you're still confirming whether you meet the program's baseline expectations, review EPIC Requirements 2026: Eligibility, Prerequisites & How to Qualify before committing to a testing window.
Key Takeaway
Since certification is valid for five years, a failed attempt doesn't just cost a retake fee - it costs scheduling delays and lost instructional credibility during the gap. Front-load preparation rather than treating the first attempt as a diagnostic.
A Focused Prep Timeline Tied to EPIC's Structure
General study techniques like spaced repetition are useful, but only when they're mapped onto EPIC's actual two-stage structure. Here's a compressed timeline built around the manuals and presentation format rather than generic advice:
Manual J and Manual S Deep Review
- Rework load calculation problems from memory, not reference
- Cross-check equipment selection logic against Manual S criteria
Manual D and Manual T
- Drill duct sizing and static pressure scenarios
- Review refrigerant piping design principles in Manual T
Manual H, Manual P, Manual 4, TT-102
- Close knowledge gaps in less-frequently-taught manuals
- Practice scenario questions across all eight coverage areas
Presentation Rehearsal and Timed Mock Assessment
- Record a full timed presentation on an assigned-style topic
- Take a full-length practice assessment under 80%-cutline conditions
This kind of manual-by-manual sequencing is covered in more depth in the EPIC Study Guide 2026: How to Pass on Your First Attempt, and you can build timed practice into your routine using the full-length simulations at EPIC Exam Prep's practice test platform.
How EPIC's Structure Compares to a Typical Credential Exam
Because there's no historical pass rate to cite, it's more useful to compare EPIC's format against a generic single-stage certification exam to understand where its risk actually sits.
| Feature | Typical Single-Stage Exam | EPIC Certification |
|---|---|---|
| Passing threshold | Often 70-75% | 80% on the knowledge assessment |
| Format | Written/computer-based only | Online assessment + live virtual presentation |
| Evaluation basis | Score alone | Score plus panel evaluation of teaching delivery |
| Content breadth | Varies by program | Eight named manuals (D, J, H, P, S, T, 4, TT-102) |
| Validity period | Varies by program | Five years |
This comparison makes the real takeaway obvious: EPIC's structural difficulty comes less from any single hard question and more from the combination of a high knowledge cutline plus a subjective, live evaluation stage. That combination is exactly why a generic "study hard" approach underperforms - you need content mastery and presentation readiness simultaneously.

Frequently Asked Questions
No. ACCA is rewriting and updating the EPIC program ahead of a planned Fall 2026 release, and no historical pass-rate statistics have been made public. Any specific percentage you see cited elsewhere is not sourced from ACCA.
The announced requirement is a minimum score of 80% on the online knowledge assessment before advancing to the virtual presentation stage. Full detail on how this threshold works is covered in EPIC Passing Score 2026: Exactly What You Need to Pass.
Yes. EPIC requires clearing both stages: the 80% knowledge assessment and a virtual presentation of assigned HVAC content evaluated by a panel of students and evaluators. Falling short on the presentation stage after passing the written portion still results in an unsuccessful attempt.
Manual J (load calculations) and Manual S (equipment selection) are foundational and interconnected, making them a high-value starting point. But since the presentation topic can be assigned from any of the eight covered manuals - D, J, H, P, S, T, Manual 4, and TT-102 - narrow prep carries real risk. See EPIC Exam Domains 2026: Complete Guide to All Content Areas for a full prioritization framework.
Successful EPIC certification is valid for five years, after which recertification is required. Given the two-stage process, most instructors treat renewal preparation similarly to first-attempt preparation rather than assuming it will be a formality.
