The ASE C1 practice test on this page helps you prepare for the Automobile Service Consultant Certification Test (C1), the ASE exam for the people who write repair orders and work with customers at the service counter. The real test has 50 scored questions plus 10 unscored research questions, 60 in all, and you get 75 minutes to answer them. It costs $62, plus a $34 registration fee for each order.
Our free quizzes follow the main C1 content areas: customer relations, sales skills, vehicle systems, maintenance intervals, warranty and recall work, and shop operations. Use them to find your weak areas, practice reading scenario questions, and get used to the pace before test day. To register, go to the official ASE website.
The Automobile Service Consultant Certification Test, known as C1, is offered by the National Institute for Automotive Service Excellence (ASE). Most ASE tests check technical repair knowledge. C1 is different: it checks the skills of the person between the customer and the shop. That includes greeting customers, writing clear repair orders, explaining recommended work, handling complaints, knowing what warranty covers, and keeping work moving through the shop.
The people who take it usually work as:
Passing the test is only part of the requirement. To earn ASE C1 certification, you must also show proof of two years of service-writing work experience. Hands-on repair experience does not count toward that requirement, so a technician with years in the bay still needs time writing service before the certification is granted.
Once earned, C1 certification is valid for five years. To stay certified, you take the shorter C1R recertification test. Many employers use C1 as a sign that an advisor can explain repairs accurately, set honest expectations, and keep the paperwork right. That matters for customer trust and for warranty claims.

Prepare for the Automobile Service Consultant Certification Test (C1) exam with our free practice test modules. Each quiz covers key topics to help you pass on your first try.
Each practice quiz below matches one content area of the Automobile Service Consultant Certification Test (C1). Start with the area you know least.
This area covers how an advisor deals with customers from the first greeting to vehicle pickup. Study active listening, asking good questions to pin down a vague concern, and writing the customer's complaint accurately on the repair order. Know how to set realistic expectations for time and cost, how to give updates when a job runs long, and how to calm an upset customer without blaming the technician or making promises the shop cannot keep. Questions also test phone manners, follow-up after service, and handling a comeback professionally. The best answer is almost always the one that is honest, documented, and keeps the customer informed.
Sales questions focus on recommending needed work in an ethical way, not on high-pressure selling. Study how to present inspection findings and turn technical causes into benefits the customer understands, such as safety, reliability, and avoiding bigger repairs later. Learn to rank recommendations by urgency, explain an estimate line by line, and handle objections about price or timing. You should know the difference between needs-based selling and padding a repair order, and why written authorization is required before any added work. Expect scenarios where a customer declines service. Know how to document the decline and when to bring it up again.
Service consultants do not repair vehicles, but they must understand them well enough to write accurate repair orders and explain findings. This area covers the purpose and common failure signs of the major systems: engine, transmission and drivetrain, brakes, steering and suspension, heating and air conditioning, and electrical and electronic systems, including hybrid and electric vehicle basics. Study how to identify a vehicle correctly using the VIN, production labels, and other identification tags, and why exact identification matters for ordering parts and checking bulletins and recalls. Practice describing symptoms in plain, precise language a technician can act on.
This area tests your knowledge of scheduled maintenance and how to recommend it correctly. Study how manufacturer maintenance schedules are organized, the difference between normal and severe service conditions, and how driving habits, climate, and towing affect which schedule applies. Know the common maintenance items, such as fluids, filters, belts, tires, and brakes, and what each one does. Learn to read a maintenance reminder or oil life system and to check a vehicle's service history before recommending work. Questions often ask which service is due, or how to explain why a service matters, without overselling items the manufacturer does not call for.
This content area covers the paperwork side of the service drive. Study the difference between manufacturer warranties, such as bumper-to-bumper, powertrain, and emissions coverage, and extended service contracts sold by third parties. Know what typically voids or limits coverage, what deductibles mean, and what documentation a claim needs. Learn how technical service bulletins differ from safety recalls. A bulletin gives repair guidance for a known issue, while a recall is a required safety correction. Practice checking a VIN for open campaigns, explaining coverage decisions to customers, and writing repair orders so warranty claims are not rejected.
Shop operations questions look at how the service department runs day to day. Study scheduling appointments to balance shop capacity, dispatching work to technicians by skill, and tracking jobs so vehicles are ready when promised. Understand how labor is estimated and billed, including flat-rate time guides, and how parts are ordered and accounted for. Know the repair order's role as the authorization record and a legal document, plus the basics of shop safety, environmental rules for waste fluids, and protecting customer property. Expect questions on communicating between the counter, the technicians, and the parts department to prevent delays and mistakes.
You take the initial C1 test on a computer at a Prometric test center. Every question is multiple choice, and most describe a situation at the service counter or in the shop and ask for the best action, explanation, or answer.
The C1R recertification test is shorter. It has 25 questions, you get 30 minutes, and you can take it at a test center or remotely through Prometric ProProctor. The initial C1 test cannot be taken remotely.
Many questions are written in the familiar ASE style: two people make statements, and you decide whether one, both, or neither is correct. Read each statement on its own before choosing. Fees, dates, and policies can change, so check the official ASE site before you buy.
C1 rewards judgment more than memorization. This plan builds the knowledge first and then the decision-making the test looks for.
Spread your study over several weeks instead of cramming. Short, regular sessions help scenario judgment stick.
Before test day: Confirm your appointment time and test center location in your myASE account. Check Prometric's rules for identification and arrival time, because a mismatched ID or a late arrival can cost you your appointment. Plan your route so you are not rushed.
During the test:
After the test: Passing the test is one requirement. You still need proof of two years of service-writing work experience before ASE grants C1 certification. Make sure your work history in myASE is complete.
If you do not pass: You must wait 30 full days before you can buy and schedule the C1 test again. Use that time well. Compare your score report with the content areas, retake our quizzes for your weakest areas, and focus on the explanations instead of just memorizing answers.
Staying certified: C1 certification is valid for five years. Before it expires, plan for the C1R recertification test, which you can take remotely through Prometric ProProctor.
The quizzes on this page are grouped by content area so you can find and fix weak spots one at a time. Here is how to get the most from them:
