- TIA does not publish a numeric pass rate for the Certified ATS Advanced Instructor program; outcomes hinge on witnessed shop proficiency plus a final exam.
- The 400-Level program is a four-day, in-person train-the-trainer course with $950 tuition and a one-year hands-on experience baseline.
- The 2026 instructor-tour syllabus covers 18 modules, four more than the 15 core modules listed on TIA's standing Certified ATS page.
- Certification lasts two years and is renewed through an online recertification exam, not a repeat of the in-person course.
Why "Pass Rate" Means Something Different for This Credential
Searches for an "ATS pass rate" usually assume a single number: a percentage of test-takers who clear a multiple-choice exam. The Certified ATS Advanced Instructor credential, governed and administered by the Tire Industry Association (TIA), doesn't work that way. There is no published pass/fail percentage for this program, and any number you see attached to "ATS" elsewhere on the internet almost certainly belongs to a different certification that happens to share the same acronym. On atsexam.com, ATS means exactly one thing: the Certified ATS Advanced Instructor program for passenger and light-truck tire technicians.
Instead of a scored multiple-choice pass rate, success in this program is defined by two hurdles candidates must clear together: a final written examination and witnessed shop proficiency demonstrations. That structure changes what "pass rate" should really mean to you as a candidate - it's less about beating a statistical average and more about arriving prepared for both a knowledge test and a hands-on evaluation in front of an evaluator.
How Certification Success Is Actually Measured
The current 400-Level Certified ATS Advanced Instructor program is a four-day, in-person train-the-trainer course carrying $950 tuition. It's built for professional passenger and light-truck tire technicians who already have field experience - TIA's standing Certified ATS requirements call for at least one year of hands-on experience before a candidate enters this track.
Two components determine whether you leave the course certified:
- A final examination covering the knowledge domains taught across the four days.
- Witnessed shop proficiency demonstrations where an evaluator observes you performing the physical procedures - not just answering questions about them.
This dual structure is the biggest reason a generic "pass rate" figure would be misleading even if one were published. A candidate can be strong on paper and still need coaching on the physical demonstration, or vice versa. If you want a full accounting of exactly what constitutes a passing outcome on the written portion, read ATS Passing Score 2026: Exactly What You Need to Pass.
Key Takeaway
Because the credential requires both a final exam and a witnessed shop demonstration, "studying harder" alone won't move the needle - you also need repetition on the physical procedures long before test day.
The 18 Modules That Determine Readiness
The 2026 instructor-tour syllabus is built around 18 modules. TIA's standing Certified ATS page presents a condensed 15-module view of the same material - it merges Torque & Clamping Force into the RIST module and drops four reference-table modules. Candidates preparing from the instructor-tour syllabus should treat all 18 as fair game, since the reference modules are exactly the kind of material that shows up in scenario-based questions.
The 18 domains are:
- Introduction
- Tires
- Wheel & Fasteners
- Raising the Vehicle
- Tire/Wheel Assembly Removal
- RIST
- Demounting, Mounting & Inflation
- Balance and Run-Out
- Puncture Repair
- Tire Conditions Analysis
- TPMS Education
- TPMS Service Requirements
- TPMS Relearn Procedures
- TPMS Diagnostics
- RMA Care and Service of Automobile and Light Truck Tires
- ALI Lift Point Guide and American National Standard
- Load & Inflation Tables
- Tire Dimensions Tables
A full breakdown of each domain - including what to expect in question style - is available in ATS Exam Domains 2026: Complete Guide to All 18 Content Areas.
RIST
RIST sits at the center of the physical demonstration portion. Candidates need fluency with torque and clamping-force procedures, since TIA folds that content into RIST on its standing summary page even though the instructor-tour syllabus lists it as a distinct module.
- Know the torque sequence and clamping-force logic cold - it's tested both on paper and at the wheel.
- Expect this module to bridge into Wheel & Fasteners and Tire/Wheel Assembly Removal.
TPMS Education, Service Requirements, Relearn Procedures, and Diagnostics
Four separate TPMS modules exist because the topic spans theory, service steps, relearn workflows, and diagnostic logic. Candidates who treat TPMS as "one topic" typically underprepare for the diagnostics and relearn portions specifically.
- Separate relearn procedures from diagnostics in your notes - they test differently.
- Expect scenario-style prompts describing a symptom and asking for the correct service path.
Where Candidates Actually Struggle
Without a published numeric pass rate, the more useful question is qualitative: which parts of the material create the most friction? Based on the structure of the program itself, three patterns stand out.
- The four TPMS modules. Splitting TPMS into Education, Service Requirements, Relearn Procedures, and Diagnostics means there's more surface area to cover than a single "TPMS" heading suggests, and each module has its own procedural nuance.
- The reference-table modules. Load & Inflation Tables and Tire Dimensions Tables are easy to skim past during a four-day course, yet they're exactly the kind of material that resurfaces in scenario questions where a candidate has to look up or recall the correct figure.
- The shop proficiency component. Because demonstrations are witnessed, hesitation or an out-of-sequence step during Demounting, Mounting & Inflation or Raising the Vehicle can cost a candidate even if their written answers were sound.

Eligibility, Experience, and Their Effect on Outcomes
TIA's standing Certified ATS requirements specify at least one year of hands-on experience before a candidate is eligible for this track. That prerequisite matters for "pass rate" reasoning: a program that filters for experienced technicians before the course even starts is going to look different than an open-entry exam, because much of the tire/wheel handling, mounting, and balancing content is reinforcing skills candidates already use daily rather than introducing them from zero.
This is also why the course is structured as a train-the-trainer program rather than a basic technician certification. Successful candidates don't just pass for themselves - they become Advanced ATS Instructors authorized to certify ATS Instructors and ATS Technicians in the field. That downstream responsibility is part of why the witnessed demonstration component exists: an instructor who can't reliably perform the procedure shouldn't be the one certifying others on it.
For the full prerequisite breakdown, see ATS Requirements 2026: Eligibility, Prerequisites & How to Qualify. If you're weighing whether the $950 tuition and four-day time commitment make sense given your role, ATS Certification Cost 2026: Complete Pricing Breakdown and Is the ATS Certification Worth It?

| Factor | Initial Certification | Recertification |
|---|---|---|
| Format | Four-day in-person course | Online examination |
| Cost | $950 tuition | Not part of the in-person tuition structure |
| Assessment type | Final exam + witnessed shop proficiency | Exam only |
| Validity period | N/A (entry point) | Two years per cycle |
| Who takes it | Experienced technicians (1+ year hands-on) | Existing Advanced ATS Instructors |
Recertification and the Two-Year Clock
Certified ATS Advanced Instructor status is valid for two years. Recertification is completed through an online examination rather than repeating the four-day in-person course. This matters for anyone thinking about long-term "pass rate" odds: the hardest part of the credential - the witnessed shop demonstration - is a one-time hurdle at initial certification, while ongoing renewal is a knowledge check you complete remotely.
That distinction should shape how you schedule your effort. The in-person course demands physical readiness and a block of four consecutive days; recertification demands that you stay current on module content without letting two years of small procedural updates slip past you. Check ATS Exam Dates 2026: Testing Windows, Deadlines & Scheduling for how to plan around both the initial course and renewal windows.
A Focused Preparation Timeline
Generic study advice rarely maps well onto a train-the-trainer program with a physical demonstration component, but a short, domain-anchored timeline in the weeks before your four-day course can reduce surprises on both the written and hands-on portions.
Foundations
- Review Introduction, Tires, and Wheel & Fasteners so terminology is second nature before the course pace picks up.
- Skim Load & Inflation Tables and Tire Dimensions Tables early - they're easy to defer and easy to forget.
Procedure-Heavy Domains
- Drill Raising the Vehicle, Tire/Wheel Assembly Removal, and RIST, since these feed directly into the witnessed shop demonstration.
- Practice Demounting, Mounting & Inflation and Balance and Run-Out on real equipment if you have shop access.
TPMS and Diagnostics
- Separate TPMS Education, Service Requirements, Relearn Procedures, and Diagnostics into distinct study blocks rather than one lump topic.
- Work through Puncture Repair and Tire Conditions Analysis scenarios.
Reference Material and Review
- Revisit RMA Care and Service standards and the ALI Lift Point Guide.
- Use a condensed review resource like ATS Cheat Sheet 2026: One-Page Review of Must-Know Facts to consolidate all 18 modules before the course begins.

Frequently Asked Questions
No. TIA does not publish a numeric pass rate for this credential. Success is determined by completing a final examination and witnessed shop proficiency demonstrations rather than by clearing a scored threshold that gets reported publicly.
There's no published data comparing the two, but structurally the shop demonstration introduces a variable the written exam doesn't: a live evaluator watching real-time technique on procedures like Demounting, Mounting & Inflation and RIST. Many candidates find the physical component requires more repetition beforehand.
The 2026 instructor-tour syllabus includes 18 modules. TIA's standing Certified ATS page shows 15 by merging Torque & Clamping Force into RIST and omitting four reference modules, but candidates following the instructor-tour syllabus should prepare across all 18.
Certified ATS Advanced Instructor status is valid for two years. Recertification is completed through an online examination rather than repeating the four-day in-person course.
Yes. TIA's standing Certified ATS requirements specify at least one year of hands-on experience for professional passenger and light-truck tire technicians before entering this train-the-trainer track.
