Auto body technician screening questions: I-CAR, ASE B-series, structural repair and refinish
On this page
Auto body technician screening questions should first sort the candidate into the right seat: non-structural repair, structural repair, refinish (painter), prep, or a combination. Then check credentials that can be verified (I-CAR training, ASE B-series tests, EPA painter training for refinish work), test whether they repair to OEM repair procedures rather than habit, and get an honest picture of their production and tools. Collision repair has changed with high-strength steels, aluminum and driver-assistance sensors, and the questions below are built around that.
This page is for collision repair. Mechanical and diagnostic technicians are covered in automotive technician screening questions, including ASE A-series tests and flat-rate pay. Welding questions for fabrication shops are in welder screening questions; collision welding is a different discipline because it follows each automaker's procedure.
Which seat is open?
| Role | What the job is | Ask the candidate |
|---|---|---|
| Non-structural technician | Bolt-on panels, outer panel repair, bumper covers, minor body work | "What share of your work was repair versus replace?" |
| Structural technician | Frame and unibody measuring, pulling, sectioning, structural welding and bonding | "Which measuring system and which welders did you use?" |
| Refinish technician (painter) | Color matching, blending, spraying in the booth, finish quality | "Which paint line, and how did you match color?" |
| Prep or paint helper | Masking, sanding, priming, booth cleaning | "Did you spray anything yourself?" |
| Combination technician | Smaller shops: body and paint by one person | "On a typical repair, what did you hand off, if anything?" |
Also ask the client whether the shop is part of automaker certification networks or insurer direct repair programs, since those bring training and procedure requirements of their own.
Credentials and how to check them
Collision technicians do not need a government license, but these credentials can be checked. Facts below are as of October 2026, from each organization's site.
| Credential | What it shows | Question to ask |
|---|---|---|
| I-CAR Platinum | An individual who completed three levels of role-specific I-CAR training (ProLevel 1, 2 and 3) in a role such as non-structural, structural, refinish or ADAS technician; kept current with six training credits a year. | "Which role is your Platinum in, and is it current?" |
| I-CAR Gold Class | A shop recognition, not an individual one. | "Was the shop Gold Class, and which role did you represent on its roster?" |
| ASE B2 to B5 | Passed collision tests (painting and refinishing, non-structural, structural, mechanical and electrical) plus two years of relevant experience; all four makes Master Collision Repair Technician; retest every five years. | "Which B-series tests, and when do they expire?" |
| ASE B6 | Damage analysis and estimating, for estimators. | Relevant only if the role includes writing estimates. |
| EPA painter training (refinish) | For covered shops, painters must be trained and certified in spray application and equipment maintenance under 40 CFR 63.11173: new personnel within 180 days of hire, refresher every five years. | "When was your spray training certificate issued, and by whom?" |
| Automaker training or certifications | Training for specific brands, often required in certified shops. | "Which brands, and was it the person or the shop that was certified?" |
Knockout questions
| Question | What a strong answer sounds like | Red flags |
|---|---|---|
| The opening is for [role]. When did you last do that work full time? | Recent, specific, in a comparable shop. | Last did structural work years ago. |
| Do you have your own tools for this role? Roughly what is in your box? | A realistic answer for the role (hand and air tools, sanders, dent tools for a body tech; spray guns for a painter). | Expects the shop to provide all hand tools when the client requires a full set. |
| The pay plan is [hourly, flag hour, or hybrid] at [rate]. Does that work? | Yes, or a clear number, and questions about how the plan works. | Expects hourly in a shop that only pays flag. |
| Some roles move vehicles or test drive. Do you have a valid driver's license? | Yes, if the client requires it. | None from the answer if driving is not part of the job. |
| Painters wear a respirator. Are you able to complete the client's respirator program after an offer? | Yes. Medical evaluation and fit testing under OSHA's respiratory protection standard happen after an offer, not on the screen. | None from the answer. Do not ask about health conditions. |
Repair procedure and structural questions
-
"Before you start a structural repair, where do you get the procedure?"
- Strong answer: the automaker's published repair procedures for that vehicle, every time, including sectioning locations, weld types and counts, and parts that must be replaced rather than repaired.
- Red flags: "I've done hundreds of these" with no mention of OEM procedures.
-
"Which welding methods have you used on collision repairs?"
- Strong answer: names the methods the procedures call for, such as squeeze-type resistance spot welding, MIG welding and MIG brazing on some steels, and rivet bonding or adhesive on aluminum, and mentions test welds before working on the vehicle.
- Red flags: MIG welds everything, including where the procedure calls for something else.
-
"How do you measure a vehicle, and when?"
- Strong answer: names the measuring system (electronic or mechanical), measures before, during and after pulls, and prints or saves the final report.
- Red flags: "eyeball and tape measure" for structural repair.
-
"What changes when you repair aluminum?"
- Strong answer: separate tools and work area to avoid contamination, specific dust extraction, different repair and joining methods, and the procedure's limits on heat.
- Red flags: no difference from steel.
Scanning, calibration and electronics
| Question | What a strong answer sounds like | Red flags |
|---|---|---|
| Did your shop scan vehicles before and after repair? | Yes, describes the process and who did it (in-house or a remote service), and what they did with codes. | Never heard of pre- or post-repair scans. |
| Which repairs triggered a sensor calibration? | Windshield, bumper or radar bracket work, alignment, as the procedure required; knows who performed calibrations. | Thinks calibration is only the dealer's problem and never flagged one. |
| How do you protect the vehicle's electronics when welding? | Follows the procedure on disconnecting or protecting modules and the battery. | Has not considered it. |
Refinish questions for painters
- "How do you match a color you have not sprayed before?" Strong: uses the paint code and variant, spray-out cards, a camera or spectrophotometer if the shop has one, checks in proper light, and blends into adjacent panels when needed.
- "Walk me through prep before the booth." Strong: cleaning, sanding grits for each step, masking, primer and sealer as the paint line specifies, final clean, tack.
- "What defects do you see most, and how do you fix them?" Strong: names defects such as runs, dirt nibs, orange peel and solvent pop, and fixes (wet sanding, polishing, respraying).
- "Which paint lines have you used?" Strong: names them, waterborne and solvent experience, and mixing system.
Production and pay
Many collision technicians are paid on flag hours, so production is a fair topic. Ask how many hours they flagged in a typical week, how many hours they were clocked in, and what mix of work produced that, and treat the number as context. A technician who flagged high numbers on bolt-on work is not comparable to one doing sectioning on aluminum.
Reading a production claim (invented example)
A candidate says they flagged 60 hours in a 45-hour week. Ask what the work was and whether they had a helper or a prepper. If most of it was replacement panels with a dedicated prepper, the number describes the shop's setup as much as the technician.
How collision experience gets overstated
- Structural claimed from non-structural work. Ask which measuring system and the last sectioning job.
- Shop credentials claimed as personal. Gold Class and automaker certifications often belong to the shop.
- Prep work described as painting. Ask who sprayed the color.
- Expired ASE tests still on the resume. Ask for expiration dates.
Scoring rubric
Pass or fail
- Recent work in the open role.
- Tools that fit the client's expectation.
- Accepts the pay plan.
- For painters: current or obtainable spray training, and can complete the respirator program after an offer.
Scored 0 to 2 each (10 possible)
- Uses OEM repair procedures without prompting.
- Welding and joining methods matched to the procedure.
- Measuring, scanning and calibration awareness.
- Refinish or repair quality habits.
- Credentials verified and current.
A paid hands-on test in the client's shop is the usual final step; keep it the same for every candidate. See how to run a job trial day.
Legal cautions
Respirator medical evaluations belong after a conditional offer. Drug tests and background or driving record checks follow state law and the client's process; see drug testing laws in hiring. Ask about incidents on the job, not injuries or workers' compensation history. This page is general information as of October 2026, not legal advice.
Questions people ask
What is the difference between I-CAR Platinum and I-CAR Gold Class?
Platinum is an individual recognition earned by completing three levels of role-specific I-CAR training (ProLevel 1 to 3) in a role such as non-structural, structural or refinish technician, and it is kept by completing six training credits a year. Gold Class is a recognition for the shop, which depends on its technicians' training across the required roles.
Which ASE tests apply to collision repair?
ASE's B-series: B2 Painting and Refinishing, B3 Non-Structural Analysis and Damage Repair, B4 Structural Analysis and Damage Repair and B5 Mechanical and Electrical Components. Passing B2 through B5 earns Master Collision Repair Technician status; B6 Damage Analysis and Estimating is for estimators. Certification requires two years of relevant experience and retesting every five years.
Does a painter need EPA training?
For shops covered by EPA's area source rule for paint stripping and surface coating (40 CFR part 63, subpart HHHHHH), which includes autobody refinishing, painters who spray-apply coatings must be trained and certified in spray application and equipment maintenance, within 180 days of hire for new personnel, with refresher training every five years. Ask whether the candidate has a current certificate and when it was issued.
How should I ask about flag-hour production?
Ask how many hours they flagged in a typical week and how many hours they were clocked in, and what kind of work made up most of it. Flag hours depend on the shop's work mix and pay plan, so treat the number as context for the conversation, not a score.
