- Frequently Asked Questions
- Part 1 (200 questions, 4 hours) is scheduled independently through Prolydian with MonitorEDU remote proctoring, not tied to fixed calendar windows.
- Parts 2 (5 hours) and 3 (3 hours) only run at DHI Classroom Series or DHI Canada events, so their dates depend on the in-person event calendar.
- You must pass Part 1 before you're eligible to sit Parts 2 and 3.
- Fees are $850 (member) or $1,050 (non-member) for the full exam, with retakes at $115 or $250 per failed part.
Part 1 Testing Windows: Year-Round Remote Scheduling
Unlike credentials that lock candidates into two or three fixed testing windows per year, the Architectural Hardware Consultant (AHC) certification handles its written exam differently. Part 1 - the 200-question, four-hour multiple-choice exam covering the full AHC exam domains - is delivered remotely through Prolydian, with MonitorEDU handling proctoring via a two-camera setup. Because it's remote-proctored rather than tied to a proctoring center's seasonal calendar, candidates typically have far more flexibility in choosing a test date once they've met eligibility requirements.
This matters for 2026 planning: instead of waiting for a specific "spring window" or "fall window" the way some certifications require, your real constraint is readiness and eligibility documentation, not a calendar quota. That said, "flexible" doesn't mean "instant" - you still need to satisfy one of the four eligibility routes before DHI will release scheduling access, and Prolydian appointment slots can fill up around popular months, so booking a few weeks ahead of your target date is wise.
Part 2 & 3 Dates: DHI Classroom Series and DHI Canada Events
Part 1 flexibility disappears once you move to Parts 2 and 3. Part 2 (Scheduling & Doors/Frames, 5 hours) and Part 3 (Specification Essay, 3 hours) are only administered in person, at DHI Classroom Series events or DHI Canada events. This means your 2026 "exam dates" for these two parts are really the DHI event calendar dates - not something you can schedule on demand the way you can with the remote Part 1 exam.
Practically, this changes how you should plan your year:
- Check the DHI Classroom Series calendar early. Events are regional and periodic, so the location and timing that work for your travel budget may only appear a few times a year.
- Bring a laptop. Both Part 2 and Part 3 require typed responses submitted through Prolydian on-site, so equipment failure isn't an excuse DHI will accommodate lightly.
- Confirm your Part 1 pass status before registering. Part 1 must be passed before you're permitted to sit the in-person parts, so registering for a Classroom Series event before your Part 1 results are finalized can create scheduling headaches.
Key Takeaway
Treat Part 1 as the gate and Parts 2/3 as the destination. Don't book travel or event registration for Parts 2 and 3 until your Part 1 pass is confirmed - the sequencing is mandatory, not just recommended.
Registration Deadlines and Fee Timing
DHI's fee structure creates its own informal "deadlines" worth planning around. The full AHC exam runs $850 for members or $1,050 for non-members (USD), covering all three parts. If you fail a part, retakes are billed separately at $115 (member) or $250 (non-member) per failed part - not the full exam fee again. That's a meaningful distinction when you're budgeting your 2026 testing year, because a retake of just Part 3, for example, costs far less than redoing the whole certification from scratch.
| Fee Type | Member Cost | Non-Member Cost |
|---|---|---|
| Full AHC Exam (all parts) | $850 | $1,050 |
| Retake per failed part | $115 | $250 |
| Renewal (3-year cycle) | $175 | $210 |
Since Parts 2 and 3 are tied to DHI Classroom Series and DHI Canada event dates, registration deadlines for those parts are effectively set by event organizers - meaning you often need to register weeks or months ahead of the actual event date to secure a seat, especially for popular regional locations. For a fuller breakdown of every fee category and how they stack up over a multi-year certification cycle, see the AHC Certification Cost breakdown.
Eligibility Route Timing: When to Start Documenting
One of the most overlooked "scheduling" factors for the AHC exam isn't the exam date at all - it's how long it takes to actually qualify to sit for it. DHI offers four eligibility routes, and each has a different timeline:
Route 1: Full DHI Course Pathway
Completing the sequence from COR101 through AHC315 is the most structured route but also the longest, since it involves multiple courses delivered on their own schedules.
- Best started 12+ months before your target exam date
Route 2: DHC Holders + AHC307/AHC310/AHC315
If you already hold the DHC credential, you only need to complete three additional courses, which can compress your timeline significantly.
- Timeline depends on course availability, not a fixed calendar
Route 3: Five Years' Experience + 100 Education Hours
This route requires documenting industry tenure alongside 100 hours of related education - plan to gather documentation well ahead of registration.
- Start compiling records and certificates now, not the week before registering
Route 4: Ten Years' Industry Experience
The most experience-heavy route requires no coursework but does require solid documentation of a decade in the field.
- Fastest to eligibility if your work history is well-documented
Whichever route applies to you, DHI also recommends the AHC390 exam preparation course before sitting Part 1. For a complete walkthrough of each pathway's requirements, read the full AHC Requirements guide.
Which Domains to Study and When
Once your eligibility route is settled and you have a target 2026 exam date, the real scheduling work begins: mapping study time against the ten domains from the official June 13, 2024 AHC Exam Content Outline. Part 1's question bank draws from all ten, so your study calendar should treat each domain as a scheduling unit, not just a topic to skim.
- Domain 1: Architectural Drawings (Construction Documents) - reading and interpreting drawing sets accurately
- Domain 2: Specifications - directly feeds into Part 3's essay-style specification writing
- Domain 3: Codes and Standards - includes NFPA 80 (2019), which is also referenced in Part 2's permitted materials
- Domain 4: Detailing (Scheduling) - the foundation for Part 2's hardware scheduling exercises
- Domain 5: Estimating - quantity and cost logic tested in Part 1
- Domain 6: Hardware - product knowledge across categories and functions
- Domain 7: Doors and Frames - paired with Domain 4 in Part 2's live exercise
- Domain 8: Project Management (Coordination) - coordination between trades and stakeholders
- Domain 9: Keying - keying systems and their documentation
- Domain 10: Electrified Hardware - increasingly emphasized product category knowledge
Because Part 2 permits the DHI Sequence and Format for the Hardware Schedule, manufacturer catalogs, and NFPA 80 (2019) - but these permissions don't extend to unrestricted open-book access on every part - you need to know exactly which materials you can lean on during each exam segment. Building that awareness into your study schedule prevents a nasty surprise on test day. For a domain-by-domain deep dive, see the AHC Exam Domains Guide.
Foundational Domains
- Architectural Drawings, Specifications, Codes and Standards
- Build reference familiarity with NFPA 80 (2019)
Scheduling and Product Domains
- Detailing (Scheduling), Doors and Frames, Hardware
- Practice with DHI Sequence and Format for the Hardware Schedule
Coordination and Specialty Domains
- Project Management, Estimating, Keying, Electrified Hardware
- Timed practice sets mimicking the 200-question, 4-hour format
If you want a structured week-by-week plan built specifically around this domain weighting, the AHC Study Guide 2026 walks through it in more depth, and our practice test platform lets you drill each domain individually before combining them into full-length simulations.
Renewal Calendar: The Three-Year CE Cycle
Passing all three parts isn't the end of your relationship with exam dates and deadlines - it's the start of a new cycle. AHC renewal operates on a three-year cycle requiring 30 continuing-education points, at least 24 of which must be technical points. Single-credential renewal costs $175 for members or $210 for non-members.
Because this cycle starts the day you certify, your 2026 certification date effectively sets your 2029 renewal deadline. Candidates who certify early in 2026 should mark their calendar for a mid-2029 review point, giving themselves a buffer to accumulate the required technical points rather than scrambling in the final months.
Building Your Own 2026 Scheduling Strategy
Pulling all of this together, a realistic 2026 scheduling approach for the AHC credential looks less like picking a single exam date and more like sequencing four separate milestones:
- Confirm your eligibility route (course pathway, DHC-plus-courses, five-years-plus-education, or ten-years) and gather documentation early in the year.
- Schedule Part 1 through Prolydian once eligibility is confirmed - this is your most flexible date, so use it to your advantage rather than rushing.
- Identify a DHI Classroom Series or DHI Canada event for Parts 2 and 3 that falls after your projected Part 1 pass date, leaving buffer time for results processing.
- Register for that event as early as possible, since in-person seats and locations are far less flexible than remote Part 1 slots.
This sequencing question - how hard each part actually is to schedule around your work and travel commitments - also ties directly into overall exam difficulty. If you're still deciding how much lead time to budget, the AHC Exam Difficulty Guide and the AHC Pass Rate breakdown both provide useful context for how much preparation time to reserve before locking in dates. And if you're weighing whether the whole multi-part timeline is worth the investment, the AHC ROI analysis covers that question directly.
Whatever your target date, running full-length timed simulations on our AHC practice test platform before you lock in a Part 1 appointment is one of the simplest ways to confirm you're actually ready for the 200-question, four-hour format rather than guessing.
Frequently Asked Questions
Not for Part 1 - it's scheduled individually through Prolydian with remote MonitorEDU proctoring, so there's no single fixed 2026 window. Parts 2 and 3, however, are tied to specific DHI Classroom Series or DHI Canada event dates, so those are effectively fixed once an event calendar is published.
No. Part 1 must be passed before you're eligible to sit the in-person Part 2 and Part 3 exams, so your scheduling sequence has to follow that order.
Retakes are billed per failed part, not as a full re-exam: $115 for members or $250 for non-members per part. Full pricing details are covered in the AHC Certification Cost guide.
You need a laptop, since responses are typed directly into Prolydian on-site. Part 2 also permits use of the DHI Sequence and Format for the Hardware Schedule, manufacturer catalogs, and NFPA 80 (2019), though these permissions don't apply universally across all three parts.
Your three-year, 30-point continuing-education cycle begins from your certification date, so the exact 2026 date you finish all three parts becomes the anchor for your next renewal deadline.
