Two things to get straight before you spend a dollar on an AMGA course.
First: the SPI is not a prerequisite for the guide track. You will read constantly that the ladder runs SPI → Rock Guide Course → Rock Guide. It doesn't. SPI appears nowhere in the Rock Guide Course prerequisites. If your goal is to become a Rock Guide, you can skip the SPI entirely, and a lot of people do, saving a course, an exam, and the travel to both.
Second: certification is not a licence. In the United States, a guide is not required by federal law to be trained in any way before guiding the public. AMGA says so itself. What actually determines whether you can legally guide is a land-manager permit, and we'll come to that, because it's the fact that most affects whether you can run a business.
Now, the programs.
What Each Credential Actually Authorizes
This is the part that matters, because working outside your certification's scope is the professional line you don't cross.
| Credential | Terrain you may work |
|---|---|
| Climbing Wall Instructor (CWI) | Artificial walls only. Two levels, Top Rope and Lead. This, not the SPI, is the gym instructor's credential |
| Single Pitch Instructor (SPI) | Single-pitch natural rock, up to Grade I, climbed without intermediate belays. Approaches and descents must present no significant route-finding, scrambling or short-roping. Not multi-pitch. Not alpine. |
| Multi-Pitch Instructor (MPI) | Multi-pitch rock up to commitment Grade II, simple approaches and descents, minimal short-roping |
| Rock Guide | Complex rock terrain at any commitment grade, no ceiling |
| IFMGA / American Mountain Guide | Everything. Rock, alpine and ski, anywhere IFMGA guides may work |
Note the first row, because it's a common and expensive mistake: if you want to teach in a climbing gym, the credential is the CWI, not the SPI. The SPI is an outdoor natural-rock certification, and its prerequisites are trad-based. Sending a gym instructor to the SPI sends them to a harder, more expensive, trad-gated course they may not need at all.
The SPI
The course is 27 hours, typically three days. The assessment is a separate two-day (16-hour) exam.
Prerequisites: 18 or older, 12 months of outdoor climbing experience, 15 traditional routes led, and comfort on 5.8 top-rope. For the exam you'll want around 40 routes total and to be comfortable leading any 5.6 trad.
One trap worth knowing: the SPI course sunsets after two years. Don't pass the assessment inside that window and you're taking the course again.
Medical: AMGA does not name a specific wilderness-medicine level for the SPI, it requires that you hold appropriate medical certification for the location where you'll work, and your certification isn't valid if that medical cert lapses.
Who it's for: someone teaching and guiding at single-pitch crags: climbing schools, camps, university programs, and the top-rope side of a guide service. It's a genuinely useful terminal credential, and for a lot of working instructors it's the only one they'll ever need.
The Guide Track
If you want to guide multi-pitch and beyond, this is the actual sequence:
- Rock Guide Course (RGC), 8–10 days. This is the entry point, and its prerequisites are serious: AMGA membership, current CPR and Wilderness First Responder (WFR), 10 trad leads at 5.10a or harder, 10 Grade III trad routes led or shared-lead, 50 multi-pitch routes led or shared-lead, and a minimum of five years' climbing experience. Passing this makes you an Apprentice Rock Guide.
- Advanced Rock Guide Course & Assistant Exam (ARGC/AE), roughly 8–10 days. Passing the exam makes you an Assistant Rock Guide.
- Rock Guide Exam (RGE), 6 days. Pass it and you are a certified Rock Guide.
Most published summaries of this pathway skip steps 2 and 3 entirely, which makes the road look about half as long, and about half as expensive, as it is.
Where the MPI fits. The Multi-Pitch Instructor is a bridge credential, and it's the one place SPI genuinely is required: MPI requires both a current SPI and completion of the Rock Guide Course. It's eight days (five course, three assessment) and it authorizes multi-pitch up to Grade II. If your work is guiding moderate multi-pitch rather than becoming a full mountain guide, it's the credential to look at.
The Top of the Ladder
The tiers, in AMGA's own language: Instructor → Apprentice Guide → Assistant Guide → Certified Guide → Aspirant IFMGA → IFMGA Guide.
And a correction to a very common misconception: the IFMGA licence is not a separate, European credential. AMGA is the sole US member association of the IFMGA, and an American earns the IFMGA licence through AMGA, by certifying in all three disciplines (Rock, Alpine, and Ski & Splitboard), plus WFR, CPR, and Professional Avalanche Level 2. The AMGA's "American Mountain Guide" title is the IFMGA licence. Same credential, two names.
It is the most demanding guiding qualification in the world, and it takes most people the better part of a decade.
The Thing That Actually Lets You Work
Here's what nobody tells the aspiring guide, and it's more consequential than any of the above.
Guiding commercially on public land requires a permit from the land manager. Not a certification, a permit:
- National Park Service: a Commercial Use Authorization (CUA) or a concession contract. Commercial services in NPS units are prohibited without one.
- US Forest Service: a Special Use Permit for all commercial outfitting and guiding.
- BLM: a Special Recreation Permit.
These are area-specific. Being permitted in one national forest authorizes precisely nothing in the next one. Permits are limited, competitive, sometimes closed for years, and frequently attached to insurance requirements and to specific AMGA certifications.
Which is where certification and legality actually meet: the land manager is often the entity that makes AMGA certification compulsory in practice, even though the federal government doesn't.
And if you're building a business rather than a career, look at AMGA Business Accreditation, a separate thing from individual certification. It audits the whole operation: permits, insurance, risk management, employment practices. It requires three years of continuous operation under the same ownership, and a certified guide or instructor for each type of terrain the business works in.
So Which One Do You Need?
Teaching in a gym? CWI.
Working single-pitch crags: schools, camps, top-rope days? SPI. It's a real, respected, terminal credential and you don't need to apologise for stopping there.
Guiding moderate multi-pitch? MPI, which means SPI and the Rock Guide Course.
Becoming a mountain guide? Go straight at the Rock Guide Course, build the trad résumé it demands, and don't spend a season on an SPI you don't need.
Opening a guide service? Certification is table stakes. The permit is the business. Start there, because it's the part that takes years.
