If you own a Corvette, Camaro, or any GM performance vehicle, the technician working on it matters as much as the parts going into it. At Chesrown Chevrolet in Delaware, Ohio, Zach holds GM’s World Class Technician certification — the highest level of technical recognition GM awards — making him one of a select number of certified specialists in the country. Whether you are preparing for track season, diagnosing an issue on a C8 Z06, or building out your Camaro for road course use, this is factory-level expertise at a GM dealership that takes performance seriously.

The Certification
What Is a GM World Class Technician?
|
The highest level of achievement a GM technician can earn.
GM World Class Technician status requires earning 8 of 9 Master Technician Certifications through GM’s Service Technical College, along with the corresponding ASE certifications in each area. Technicians must then maintain 100% of their required training annually to keep the designation active. GM recognizes this as the highest level of achievement any GM technician can earn.
|
To put that in context: earning WCT status means passing GM Master Technician Certifications across areas including Electrical/Electronics, Engine Repair, Brakes, Steering and Suspension, Drivetrain, Automatic Transmission, HVAC, and Engine Performance — each paired with the corresponding ASE certification. It is not a single exam or a tenure-based award. It is a demonstrated, tested, and annually maintained credential. For Corvette and Camaro owners specifically, this matters because:
| ● These vehicles carry complex powertrains — the LT6 flat-plane V8 in the C8 Z06 and the LT4 supercharged engine in the Camaro ZL1 — that require factory-specific knowledge to diagnose and service correctly |
| ● Many independent shops lack access to GM’s proprietary GDS2 diagnostic tools, used for factory-level fault analysis |
| ● GM warranty and powertrain coverage integrity depends on work performed by certified GM technicians using OEM procedures |
| ● Performance builds and track-use vehicles require precise calibration and setup knowledge that comes from deep familiarity with GM’s engineering parameters |
OEM Tools. Factory Standards. Actively Maintained.
Zach works exclusively with GM factory tooling, including GDS2 diagnostics, factory torque specifications, and OEM-sourced components. His World Class status is not a one-time achievement — it requires completing 100% of required GM training annually to remain active. That means the credential you see on the wall reflects work he did this year, not a test he passed a decade ago.

Why Chesrown
Why Trust a GM Dealership for Performance Service?
Independent shops may offer lower base labor rates, but they generally lack factory diagnostic tools, OEM technical service bulletins, and GM-certified training. For vehicles operating outside of normal parameters — track cars, modified platforms, or late-model performance vehicles with complex electronic systems — these gaps matter.
