This guide explains how California’s BAR licensing works for smog check inspectors and repair technicians. You’ll also learn the main training, application steps, and the paperwork you should prepare before you submit.

Imagine you finished your smog training and you’re ready to work—but every page asks for a different application, fee, license, and proof. The goal of this post is to remove that confusion and help you move step by step.


BAR licenses you can apply for

BAR issues both business licenses and individual licenses related to smog and safety work.

Individual licenses for people

Role What you do Key licensing training
Smog Check inspector Inspection and certification of emissions control systems Requires Smog Check training (Level 2)
Smog Check repair technician Repair and diagnosis of emissions control system failures (does not perform inspections) Needs the same base qualifications as inspector, but not Level 2 inspection training

Business licenses for shops

Business type What you do Connection to smog
Automotive repair dealer Runs vehicle repair work for compensation Often a prerequisite for smog-related licenses
Smog Check station Performs smog check services Station license
STAR station Meets STAR program standards and can inspect directed vehicles STAR certification
Vehicle safety systems inspection station Safety systems inspection and repair Separate licensing path

The training requirements that matter most

Smog licensing depends heavily on training. The BAR training page lists course hours and what each course is for.

Level 1 vs Level 2 Smog Check training

Training level Minimum hours Who needs it What it focuses on
Level 1 Engine and emission control 68 hours (minimum) Required for many inspector applicants with minimal or no experience Basic engine/emission control theory and operation
Level 2 Smog Check training 28 hours (minimum) Required for all Smog Check inspector applicants Procedural knowledge and skills to perform smog checks

Training hours for a repair technician

For Smog Check repair technician, BAR uses qualification paths that can include diagnostic and repair training. One listed course is:

Course Minimum hours Who it helps
Diagnostic and repair training 72 hours (minimum) Used to qualify applicants to take the repair technician exam in certain cases (including applicants with at least two years of engine performance experience)

Qualification rules for Smog Check licenses

Both the Smog Check inspector and Smog Check repair technician licenses share the same qualification requirements—except the inspector also requires Level 2 training.

Qualification options for inspector and repair technician

To qualify, you must meet one of the following main paths, then do the extra Level 2 step for inspector:

1) Training path

  • Complete engine and emission control (Level 1) training within the last two years.

2) Certification path

  • Hold ASE certifications:
  • Electrical/Electronic Systems (A6)
  • Engine Performance (A8)
  • Advanced Engine Performance Specialist (L1)

3) Education path

  • Have one year of engine performance experience and also one of these:
  • Associate degree (AA/AS) or higher in automotive technology
  • Or a certificate in automotive technology with at least 720 hours of coursework including 280 hours in engine performance
    (From a state accredited or recognized school)

4) Experience path

  • Have two years of engine performance experience
  • And completed diagnostic and repair training within the last five years

5) Military path

  • Comparable military education or experience

The extra requirement for the inspector license

After meeting one path above, Smog Check inspector applicants must also:
- Complete Smog Check (Level 2) training within the last two years.


Step by step application process after training

Once your training is done, the process is mostly about applying correctly, uploading the right documents, and paying the fee.

A practical checklist for your Smog Check license

Step What you do What to prepare
1 Gather identity and required personal info Social Security number or ITIN, and government photo ID
2 Gather required automotive credentials ASE certifications (for inspector/technician qualification)
3 Choose the correct license application Smog Check inspector vs Smog Check repair technician
4 Pay the application fee Credit card for the application fee
5 Submit and track Online submission helps with faster processing, document upload, and email updates

If you are also opening a shop

Your situation changes because you may need both individual and station-level steps. If you plan to open a shop, BAR notes you would use the smog technician application plus the station application when applicable.

A simple example:
- You finish smog check training to become a technician.
- You also rent a building and want to run a smog test station.
- You then submit both your individual application and your shop’s station application documents.


Common obstacles and delays that slow people down

Most delays are not mysterious. They usually come from avoidable issues.

Obstacle What it looks like How to avoid it
Missing documents Application sent without proof that matches the qualification route Before submitting, confirm each requirement is included
Incomplete forms Required fields left blank or mismatched info Fill everything carefully and use the same name/address format
Not uploading documents (if online) Paper documents sent but not readable or missing pages If possible, apply online to upload documents
Confusion about which training Level 1 done, but inspector needs Level 2 Match training to the exact license type

Where to find official application forms

BAR provides application entry points on its website under licensing pages. Use BAR’s Apply for a license area and select the correct path for:

Submitting applications and the benefit of online

BAR explains that applying online can:

How long does it take and what to do if you don’t get confirmation

BAR indicates processing times vary, so the best approach is:
1. Submit as soon as you’re ready.
2. Watch for the expected confirmation window.
3. If you do not receive confirmation within that expected timeframe, the recommended action is to follow up with BAR.

For duration questions, BAR provides a customer support approach via calling BAR to ask about licensing process length.
