- The CRD is an IGSHPA legacy credential; no unrestricted public 2026 testing calendar exists for new candidates.
- Legacy courses run case by case, and only when a utility, state or provincial program requires them.
- HRAI's advertised February 24-26, 2026 virtual CRD course does not prove it ran or that enrollment is open.
- Active holders can renew indefinitely, but lapsed legacy credentials cannot be reinstated.
Why the CRD Has No Fixed 2026 Calendar
Most credential date articles hand you a table of testing windows, a registration cutoff and a results timeline. For the Certified Residential Geothermal Designer credential, that kind of calendar would be misleading. The CRD is issued by the International Ground Source Heat Pump Association (IGSHPA), and it now sits in a legacy category. Training for it is no longer delivered on a standing public schedule.
That changes what "exam dates" means for this credential. Instead of asking which Saturday in 2026 you can sit the exam, the useful questions are these: Is a legacy offering available to me right now? If I already hold the credential, when does my renewal fall due? And if I'm starting fresh, should I be looking at the CRD at all?
This guide answers those questions using only what IGSHPA and its partners have documented. If you want the broader picture of what the credential is before digging into timing, start with What Is CRD Certification? and CRD Requirements 2026: Eligibility, Prerequisites & How to Qualify.
The Legacy Status Behind the Scheduling Question
IGSHPA addressed the credential's status directly in its white paper on sunsetting legacy training courses and certifications (White Paper 251229, revision dated January 14, 2026). The paper identifies the Certified Residential Geothermal Designer among the legacy credentials and reports that normal legacy training was replaced by the end of 2025.
Three practical consequences follow from that status:
- Legacy courses are considered case by case. IGSHPA's current Training & Certification information indicates legacy courses are offered only when a utility, state or provincial program requires them. They are not a walk-up product.
- Active holders keep their path. The white paper indicates active CRD holders may continue renewing indefinitely with the required continuing education, provided the certification does not lapse.
- Lapsed credentials stay lapsed. IGSHPA's current FAQ says lapsed legacy credentials cannot be reinstated.
A related point trips up many readers: taking the GRSD examination is a separate, optional upgrade path. It is not an automatic renaming or replacement of the CRD. Keeping those two tracks distinct matters, and the transition section below returns to it.
The HRAI February 2026 Listing: What It Proves and What It Doesn't
If you search for CRD dates, you may find HRAI's 2025-26 Courses Schedule, which advertised a virtual CRD course for February 24-26, 2026. That is a real document, and it is the main conflicting signal in the record. It deserves a careful reading rather than a quick conclusion in either direction.
| Signal | What it says | What it does not establish |
|---|---|---|
| HRAI 2025-26 Courses Schedule | Advertised a virtual CRD course, February 24-26, 2026 | That the course actually ran, or that seats are open today |
| IGSHPA historical event listing | A CRD online course with HRAI on February 26-27, 2025 | A 2026 repeat, or a current testing window |
| IGSHPA white paper (rev. Jan 14, 2026) | Normal legacy training replaced by end of 2025; legacy handled case by case | A published public calendar for legacy sessions |
| IGSHPA Training & Certification page | Legacy courses offered only when a program requires them | Unrestricted new-candidate enrollment |
The honest summary: a past schedule is evidence of intent at the time it was published, not proof of delivery or current availability. Anyone planning around a dated session should confirm directly with IGSHPA or HRAI before paying for anything or arranging time off.
How to Verify a Current Offering Before You Plan Anything
Because the CRD has no standing public schedule, verification is the actual "scheduling" skill here. Work through these steps in order:
- Check IGSHPA's Training & Certification page. It is the issuer's current statement on what is and isn't offered, including the case-by-case legacy language.
- Identify whether a program requires the CRD. Because legacy courses are tied to utility, state or provincial program requirements, ask whether the program you work under (or hope to work under) specifically calls for this credential.
- Contact IGSHPA directly with a specific question. Ask whether a legacy CRD offering is approved and open for your situation, and request the details in writing.
- If a partner such as HRAI lists a session, confirm with the issuer that the listing is current and that it leads to the credential, not just course attendance.
- Do not pay until you have a named session, date and confirmation. A vague promise of "a future session" is not a plan.
What the Historical Preparation Course Covered
Even without a live calendar, understanding what the preparation course covered tells you what the credential represents and what a legacy session would teach. IGSHPA's historical event listing for the CRD online course with HRAI (February 26-27, 2025) presented nine preparation-topic headings. These are curriculum headings, not official weighted exam domains, and they do not establish exhaustive exam coverage or identify a highest-weighted area.
Domains 1-3: Foundations
The opening headings establish why ground source systems are worth recommending and what physically makes up a system.
- Ground Source Heat Pump Benefits - the case for geothermal in residential applications
- System Components - what a residential installation consists of
- Heat Pump Types - the equipment categories a designer must distinguish
Domains 4-6: The Design Workflow
The middle headings follow the order a designer actually works in: process, then energy picture, then loads.
- Design Process - the sequence of decisions from site to specification
- Energy Requirements - what the building needs from the system
- Load Calculations - sizing the system to the structure
Domains 7-9: Performance, Sizing and Economics
The closing headings tie the design to the real site and to the customer's decision.
- Parameters that affect different types of heat pump performance, site, geology and soil conditions - why ground conditions change results
- Heat pump and pipe design - equipment selection and the ground loop piping
- Economics of design - the financial case a residential designer must be able to present
For a closer look at how these nine areas fit together, see CRD Exam Domains 2026: Complete Guide to All 9 Content Areas. If you want to gauge the effort involved, How Hard Is the CRD Exam? Complete Difficulty Guide 2026 covers the conceptual demands, and CRD Training discusses the course side.
Renewal Timing for Active CRD Holders
For people who already hold the credential, the most important dates in 2026 are not exam dates at all. They are renewal dates. IGSHPA offers current renewal products with one-, two- or three-year terms, and your own certification record determines when your next renewal falls due. Check your IGSHPA certificate and account for the exact expiration rather than estimating.
Several mechanics affect timing:
- CEU documentation is required for processing. Gather it before you try to renew, not after.
- CEU points are not classroom hours. IGSHPA describes eight CEU points per three-year cycle. Do not assume that eight hours of class equals eight points.
- The membership term must cover the renewal term. If you claim the member rate on a multi-year renewal, your membership must run at least as long as the discounted certification term.
- Fee policy has been in effect since January 1, 2024. IGSHPA's published renewal fee policy dates from then.
Key Takeaway
Build your renewal timeline backward from your expiration date. Allow time to collect CEU documentation, confirm your membership term covers the renewal period you want, and submit before the credential can lapse. Because lapsed legacy credentials cannot be reinstated, there is no safety net on the far side of the deadline.
Renewal Terms and Costs at a Glance
These figures are renewal charges for active holders. They are not initial exam fees, and no initial exam fee has been verified for the legacy credential.
| Item | Cost | Notes |
|---|---|---|
| CRD renewal, member rate | $75 per year | Available in one-, two- or three-year terms |
| CRD renewal, non-member rate | $225 per year | Available in one-, two- or three-year terms |
| Individual membership (currently employed) | $125 per year | Unnecessary if covered by an eligible business, community or utility membership |
| CEU requirement | 8 CEU points per 3-year cycle | Documentation required for processing |
A quick comparison shows why membership status matters. The gap between the member and non-member renewal rate is $150 per year, while individual membership costs $125 per year. For a holder who would otherwise pay the non-member rate, joining can come out ahead, and for anyone already covered through an eligible employer or utility membership, the member rate may be available at no extra membership cost. Confirm your coverage before purchasing.

The Lapse Rule: The Deadline That Matters Most
Among all the dates in this article, the expiration date on an active credential is the only one that is both certain and consequential. IGSHPA's current FAQ states that lapsed legacy credentials cannot be reinstated. Combined with the legacy status described above, that means a missed renewal is not an inconvenience; it is potentially permanent.
Practical protections: calendar your expiration date with reminders well ahead of time, track CEU activity as you earn it, and confirm membership coverage early. Whether the credential is worth maintaining for your career is a separate question, addressed in Is the CRD Certification Worth It? Complete ROI Analysis 2026 and, for earnings context, CRD Salary Guide 2026: Complete Earnings Analysis.
Separating Transition Planning from CRD Scheduling
The GRSD examination is IGSHPA's separate path, and it is described as an optional upgrade. It should be planned on its own terms. Do not carry assumptions across from one credential to the other.
- Do not transplant GRSD details onto the CRD. Exam fees, timers, reference rules and validity periods belong to the GRSD and should be confirmed from IGSHPA's current materials for that credential.
- Taking the GRSD does not rename your CRD. It is an additional credential, not an automatic conversion.
- Keep renewing the CRD if you want to retain it. Pursuing the upgrade does not pause the CRD's own renewal clock.
If you are weighing whether to renew a legacy credential, pursue the upgrade, or both, the deciding factors are usually your program requirements and your employer's expectations. Employers and program administrators in the residential geothermal space are the ones who ultimately decide which credential they recognize, so ask them directly. For a view of the roles that value the credential, see CRD Jobs.
Sequencing Your Preparation Around Real Dates
Whenever a legitimate session is confirmed, whether a legacy course tied to a program requirement or any related offering, the useful way to use the weeks beforehand is to follow the design workflow from the nine preparation topics. This is the one place generic scheduling advice earns its keep, and only because the order mirrors how a designer actually works.
Foundations
- Ground Source Heat Pump Benefits, System Components and Heat Pump Types
- Build vocabulary first; every later calculation assumes it
Process and Energy
- Design Process and Energy Requirements
- Learn the order of decisions before the arithmetic
Calculation-Heavy Work
- Load Calculations, then Heat pump and pipe design
- Give this the most practice time, since errors here cascade into sizing
Site Factors and Economics
- Performance parameters, site, geology and soil conditions, then Economics of design
- Finish with timed mixed practice using our practice tests
Load calculations and pipe design are the areas where candidates typically need the most repetition, because the ground and the building both feed the result. For a structured approach to drilling those topics, read the CRD Study Guide 2026: How to Pass on Your First Attempt, and keep the CRD Cheat Sheet 2026: One-Page Review of Must-Know Facts handy for last-day review. Because no current pass-rate data has been verified, use the discussion in CRD Pass Rate 2026: What the Data Shows as context for what is and isn't known rather than as a benchmark. When you are ready to test your recall on the nine topic areas, you can try a practice test to find weak spots before any live session.
Frequently Asked Questions
No unrestricted public window has been verified. The CRD is a legacy IGSHPA credential, and legacy courses are considered case by case, offered only when a utility, state or provincial program requires them. New candidates should confirm any specific offering directly with IGSHPA before planning around it.
That cannot be confirmed from the schedule alone. HRAI's 2025-26 Courses Schedule advertised it, but a published schedule does not prove the course ran or that enrollment is open now. Contact IGSHPA or HRAI for current status.
No. IGSHPA's current FAQ says lapsed legacy credentials cannot be reinstated. Active holders can renew indefinitely with the required continuing education, so the safest course is to renew before the expiration date.
Current renewal products are $75 per year at the member rate and $225 per year at the non-member rate, with one-, two- or three-year terms. CEU documentation is required, and IGSHPA describes eight CEU points per three-year cycle. See the full cost breakdown for context.
No. The GRSD examination is a separate, optional upgrade path, not an automatic renaming or replacement of the CRD. Plan and verify its requirements separately rather than assuming CRD details carry over.
