- A single T1 test order costs $96: a $62 test fee plus a $34 registration fee, before sales tax.
- The registration fee is charged per order, so bundling several ASE tests in one order spreads that $34 across them.
- Buying a test starts a 90-day window; waiting past it risks losing the fee you already paid.
- T1R recertification uses the same $62 and $34 fees, with test charges capped at $186 per order.
The T1 Cost at a Glance
The Medium-Heavy Truck Certification - T1 Gasoline Engines credential is administered by the National Institute for Automotive Service Excellence (ASE) and delivered through Prometric. It covers gasoline engines in Class 4 through Class 8 trucks and tractors. The good news for anyone budgeting: the mandatory costs are small, fixed, and published on ASE's registration page. There is no application fee, no proctor surcharge for initial testing, and no mandatory training purchase.
Here is the core price picture for the initial test:
| Cost Component | Amount | Notes |
|---|---|---|
| T1 test fee | $62 | Per test |
| Registration fee | $34 | Per order, not per test |
| Single-test order total | $96 | Before applicable sales tax |
| Sales tax | Varies | Applied where applicable |
That $96 figure is the number most candidates should carry in their heads. Everything else in this article is about the edges: what changes if you add tests, retake, renew, or spend on preparation. If you want the broader context on whether this spend pays off, the T1 certification ROI analysis and the T1 salary guide cover the return side of the ledger.
How the $62 Test Fee and $34 Registration Fee Work
The two-part fee structure is the single most misunderstood element of ASE pricing, so it is worth slowing down on.
Test fee: charged per test
Every ASE test you add to an order carries its own $62 test fee. T1 is one test, so on its own it contributes $62. The exam itself is 60 questions (50 scored plus 10 unidentified, unscored research questions) with 75 minutes of testing time, all computer-based multiple choice.
Registration fee: charged per order
The $34 registration fee attaches to the order, not the individual test. This matters when you plan how many credentials to pursue:
- T1 alone: $62 + $34 = $96.
- T1 plus another test in the same order: you pay the $34 once, then $62 for each test. Two tests would be $124 + $34 = $158, before tax.
- T1 in one order, a second test in a separate later order: you pay $34 twice. Splitting orders when you didn't need to is the easiest way to waste money.
Because T1 is not required for Master Medium-Heavy Truck Technician status, many technicians treat it as a specialty add-on rather than a stepping stone. That makes it a natural candidate to batch with tests you are already taking, or to take alone if gasoline engine work is specifically what your shop does.
Sales Tax and the Costs Outside the Fee Schedule
ASE's published numbers are stated "before applicable sales tax." The exact tax depends on where the transaction is treated as occurring, so the safe approach is to treat $96 as the floor and check your final cart total at checkout. Do not assume a specific tax figure in advance; it varies.
Beyond the fee schedule, the real-world extras are small but real:
- Travel to the test center. Initial certification is delivered at a Prometric test center, so fuel, parking, or a half-day off work are your main incidental costs. Remote proctoring is available for recertification, not for the initial exam.
- Time off work. The test itself is 75 minutes, but check-in and travel make it a half-day for most people.
- Scratch paper and pencils are supplied at the test center, so you do not need to buy supplies.
What a Retake Really Costs
Failing is not catastrophic financially, but it is not free. Each attempt requires a new purchase, and the rules shape both cost and timing:
- After a Pass or a Fail result, a 30-full-day wait applies before you can repurchase and schedule the same test.
- A retake is a new order, so you pay the $62 test fee and a fresh $34 registration fee: another $96 before tax for a single-test order.
- Every purchase carries a 90-day completion window. If you buy and then fail to test within 90 days, you risk forfeiting the money.
One more clarification: no numeric passing score or current test-specific pass rate was verified in ASE's public sources, so be cautious of any site that quotes a precise cutoff. For what is and isn't known, see our pages on the T1 passing score and the T1 pass rate.
Experience Credit: The Cost Nobody Prices In
Passing the test alone does not make you certified. ASE certification requires passing the test and ASE approval of two years of relevant full-time Repair Technician experience (or the part-time equivalent). Approved education or training can substitute for part of that requirement, and candidates are allowed to test before meeting it.
This produces a pricing wrinkle: you can pay your $96 and pass the exam while still being uncertified because the work-experience side is pending. That is not a loss, since the passing result is held toward certification, but you should plan for it rather than be surprised.
What the substitution rules mean for your wallet
- Education/training substitutions are reviewed and approved by ASE, and the listed substitutions cannot be combined with one another.
- ASE's detailed experience table allows two years of credit for a completed ASE-accredited OEM-sponsored co-op, including its hands-on component.
- The January 2026 handbook summarizes vocational credit as up to half, so if you are counting on school hours to cover part of the requirement, verify how ASE will actually credit them before you spend on the exam.
If you are weighing whether to pay for a program mainly to shorten the experience clock, read the full breakdown in our T1 requirements guide before committing tuition dollars.
Recertification: T1R Pricing and the $186 Cap
T1 certification is valid for five years. To renew, you pass T1R, a shorter test: 25 questions, no added research questions, and a 30-minute limit. To be eligible, you must have previously passed the corresponding initial certification test.
Recertification fees mirror the initial structure:
| Item | Amount |
|---|---|
| Test fee (per recertification test) | $62 |
| Registration fee (per order) | $34 |
| Cap on recertification test charges per order | $186 |
| Maximum per order including registration | $220 |
The cap is useful if you hold several certifications that expire together: once you reach three recertification tests in one order, additional tests do not add to the test charges, so the total tops out at $220 including registration (all before applicable sales tax). For a technician holding only T1, you simply pay $96.
Where you can renew
- At a test center, or
- Through Prometric ProProctor remote testing, subject to its technical and secure-environment requirements. Previously certified candidates, including those whose credential has expired, may use either route.
Where Prep Money Goes (and Where It Doesn't Need To)
The exam fee is the smaller cost for many candidates; prep decisions are where totals diverge. One fact simplifies things: ASE's listed truck practice-test products cover T2, T4, T6 and T8. There is no official ASE practice test for T1, so T1 preparation can lean on the free official study-guide samples from ASE's Medium/Heavy Truck study guide.
That means a lean, legitimate budget is possible. A structured approach to spending:
- Start free. Read the official study guide's test specifications and task lists. They show exactly how the 50 scored questions are distributed.
- Add targeted practice. Use our practice tests to rehearse the question style, including diagnostic scenarios and Technician A/B items.
- Fill gaps with shop manuals and service information you already have access to through your employer.
Let the domain weights drive your spending
Because the exam is weighted, spending time (and money) evenly is inefficient. These are the official areas and their share of the 50 scored questions:
General Engine Diagnosis (28%)
The largest area at 14 of 50 scored questions. Diagnostic reasoning dominates here: interpreting symptoms, test results, and what to check next.
- Pay for or borrow the best diagnostic references you can
- Practice Technician A/B reasoning on no-start, misfire, and performance complaints
Computerized Engine Controls Diagnosis and Repair (16%)
Eight scored questions. Sensors, actuators, scan data interpretation, and circuit-level thinking are all fair game.
- Scan-tool data and waveform thinking pay off here
The remaining areas, from Ignition System and Fuel/Air Induction/Exhaust (12% each) through Emissions Control (10%), Cylinder Head and Valve Train (8%), Engine Block (8%), and Lubrication and Cooling (6%), each have a smaller footprint. Our complete guide to the eight T1 content areas breaks down what each one tests.
Key Takeaway
Because 44% of the scored questions come from just two areas (General Engine Diagnosis and Computerized Engine Controls), putting your limited prep budget into those two areas gives the best return. Don't buy broad, generic material when targeted practice is available.
One short note on scheduling prep to match the fees
The 90-day purchase window is your built-in deadline. A sensible sequence is to study before you buy, then purchase once you are consistently handling diagnostic scenarios. Spend the first block on General Engine Diagnosis, the second on Computerized Engine Controls, then rotate through ignition, fuel/air/exhaust, and emissions. Save the 6-8% areas for a final pass. For a fuller plan, see the T1 study guide, and keep the T1 cheat sheet handy for last-week review.
Three Budget Scenarios Side by Side
To make this concrete, here are three realistic paths using only fixed fees from ASE (before applicable sales tax). Prep spending is left out because it varies by person.
| Scenario | Orders and Fees | Total Exam Fees |
|---|---|---|
| Pass on the first try, T1 only | One order: $62 + $34 | $96 |
| Fail once, then pass | Two orders: ($62 + $34) x 2 | $192 |
| T1 batched with one other test, both passed | One order: $62 x 2 + $34 | $158 |
Notice how small the gap is between best and worst cases. The fee schedule is forgiving; the real cost of failing is the 30-day delay and the lost momentum, not the dollars. Expect to renew on a five-year cycle, adding a T1R order of $96 for a T1-only holder.
If you are still orienting yourself on the credential itself, our explainers on what T1 certification is and the T1 exam dates and scheduling fill in the basics, and our main practice site is the place to test your readiness before you pay for an order.
Frequently Asked Questions
A single-test order is $96: a $62 test fee plus a $34 registration fee, before applicable sales tax. The registration fee is charged per order, so adding more tests to the same order only adds $62 each.
Yes. A retake requires a new order, which means a new $62 test fee and a new $34 registration fee. You must also wait 30 full days after a Pass or Fail result before repurchasing and scheduling the same test.
Testing must be completed within 90 days of purchase. Buy only when you can realistically sit for the exam within that window, or you risk losing the fee.
Recertification uses the same $62 test fee and $34 order fee. Recertification test charges are capped at $186 per order ($220 including registration), before applicable sales tax. The T1R test has 25 questions and a 30-minute limit.
No. ASE's listed truck practice-test products are T2, T4, T6 and T8. For T1, candidates can use the free official study-guide samples and supplement with independent practice resources.
Yes. Candidates may test before meeting the experience requirement, but certification itself requires passing the test and ASE approval of two years of relevant full-time experience (or part-time equivalent), with approved education or training substitutions allowed.
