The ASE A1-A8 exam at a glance
The ASE A1 to A8 tests are the eight Automobile and Light Truck certification tests from the National Institute for Automotive Service Excellence: A1 Engine Repair, A2 Automatic Transmission/Transaxle, A3 Manual Drive Train and Axles, A4 Suspension and Steering, A5 Brakes, A6 Electrical/Electronic Systems, A7 Heating and Air Conditioning and A8 Engine Performance. Each is a separate multiple-choice test: A1, A2 and A5 have 45 scored questions in 75 minutes, A3 and A4 40 in 60 minutes, A6 50 in 90 minutes, and A7 and A8 50 in 75 minutes, and every certification test adds 10 unscored research questions. ASE does not publish a passing score. Certification also needs two years of documented work experience (up to half from vocational training), lasts five years, and passing all eight earns Master Automobile Technician status. A first-time certification test is taken at a test center, while recertification tests can also be taken remotely, and the A-series tests can show each question side by side in Spanish.

How It Works
Train One A-Test at a Time
Eight training sets, one for each test from A1 to A8, each covering that test's content areas in ASE's proportions. Questions you miss come back until you have mastered them.
Mixed Practice Tests
Four practice tests of 50 questions drawn from all eight A-tests, with a 70% readiness line. No question appears in more than one test, and every Ohm's law and pressure reading is worked through in the explanation.
Built on the ASE Task Lists
Each A-test is its own exam with its own task list. These are the scored questions ASE lists for each one; every practice test takes 5 to 7 questions from each test in the same proportions.

Share FeedbackHow to Pass the ASE Tests
1. Study the task list for the test you booked
Every ASE question ties to a task on that test's list, and not every task appears on every form. Work through the training set for your test and note the tasks you have not done in the shop.
2. Think in diagnosis, not part names
Most questions give a symptom and a test result and ask for the likely cause or the next step. Learn what each test isolates: compression versus leak-down, pressure with the valve closed, voltage drop under load.
3. Know your electrical math
Ohm's law, series and parallel resistance, power in watts and voltage drop appear in A6 and across A1, A7 and A8. Be quick with them.
4. Answer every question
Each certification test includes 10 unscored research questions you cannot tell apart from the rest, so give every question your best answer. Aim for 80% or better on the practice tests before you book.
ASE Test Frequently Asked Questions
What are the ASE A1 to A8 tests?
They are the eight Automobile and Light Truck certification tests from the National Institute for Automotive Service Excellence (ASE): A1 Engine Repair, A2 Automatic Transmission/Transaxle, A3 Manual Drive Train and Axles, A4 Suspension and Steering, A5 Brakes, A6 Electrical/Electronic Systems, A7 Heating and Air Conditioning, and A8 Engine Performance. Each is a separate test and a separate certification. Passing all eight, with the required work experience, earns Master Automobile Technician status.
How many questions are on each ASE test?
ASE's 2026 study guide lists 45 scored questions in 75 minutes for A1, A2 and A5; 40 in 60 minutes for A3 and A4; 50 in 90 minutes for A6; and 50 in 75 minutes for A7 and A8. Every certification test also carries 10 unscored research questions, so A1 has 55 questions in all. ASE does not publish a passing score, so the practice tests here use 70 percent as a readiness line.
How is this practice organized?
There is one training set for each A-test, 40 questions each, written to that test's official task list and split across its content areas in ASE's proportions, so you can train only the test you are booked for. The four practice tests mix all eight areas, 50 questions each, weighted by how many scored questions each test has.
Do I need work experience to be ASE certified?
Yes. Passing a test is only part of certification: ASE also requires documented, relevant work experience, two years for the A-series tests, and up to half of it can come from appropriate vocational training. Certifications are valid for five years, then you take the shorter recertification test.
Are these the real ASE test questions?
No. Every question is original, written by Tigertest from the task lists in the Official ASE Study Guide and from primary rules such as FMVSS 116, 126 and 138 and the EPA's Section 609 servicing requirements. Like the real tests, every question is multiple choice with one correct answer. Tigertest is not affiliated with ASE.
I teach an automotive technology program or ASE prep class. Can my students use Tigertest?
Yes, for free. Make a class at tigertest.io/teach, post one link, and students join with just their name. You see who practiced, their test scores and the topics your class misses most.
ASE A1-A8 sample questions and answers
6 of the 320 practice questions, one from each topic, with the answer explained.
1. What is a common result of a stuck-closed PCV valve?
- A.Coolant in the engine oil
- B.Oil leaks at the seals
- C.A lean mixture at idle
- D.Low oil pressure at idle
Answer: B. With the PCV valve stuck closed, blow-by gases cannot be drawn out, so crankcase pressure rises and pushes oil past seals and gaskets.
2. Before road testing a vehicle for a shift complaint, what should be checked first?
- A.Clutch pack clearance
- B.Valve body bolt torque
- C.Planetary carrier end play
- D.Fluid level and condition
Answer: D. Low, overfull or burnt fluid causes many shift complaints, so level and condition are checked first, using the service information procedure for that unit.
3. Water is found in a front axle after a vehicle forded a stream. What should be checked?
- A.The axle vent and hose
- B.The front axle ratio
- C.The ring gear runout
- D.The transfer case chain
Answer: A. When a hot axle is plunged into cold water it cools and draws water in through a missing, damaged or low-mounted vent hose. The lubricant is replaced and the vent repaired.
4. A sealed hub bearing unit has end play beyond specification. What is the repair?
- A.Repack the bearing
- B.Shim the hub flange
- C.Replace the hub assembly
- D.Tighten the axle nut further
Answer: C. Sealed hub units are not adjustable or serviceable. Excess end play means the bearing is worn, so the whole hub assembly is replaced and the axle nut torqued to specification.
5. Before rear pads are replaced on a caliper with an electronic parking brake, what is usually done?
- A.Bleed the master cylinder
- B.Remove the parking cable
- C.Put the EPB in service mode
- D.Disconnect the ABS control module
Answer: C. The EPB motor holds the piston out. A scan tool or the vehicle's own procedure retracts it in service mode so the piston can be pushed back without damage.
6. A park assist system beeps constantly with nothing behind the vehicle. What is a common cause?
- A.A dirty or damaged sensor
- B.A weak starter motor
- C.A low washer fluid level
- D.A burned-out stop lamp bulb
Answer: A. Mud, ice, a damaged sensor or one aimed wrong after bumper repair can make the system see an object that is not there, so the sensors are inspected first.
