Build the skills to work on any vehicle — including the ones taking over the road
A comprehensive 3-month certified program that takes you from workshop fundamentals to advanced EV, hybrid, and ADAS diagnostics — everything you need to work confidently on modern vehicles. Build industry-ready skills across every major automotive system, from engine internals to driver-assist technology.

"I teach every 'why' behind the procedure — because a technician who truly understands a system doesn't just fix the fault in front of them, they prevent the next one."— Renstay

Workshop Safety and Tool Handling
Establishes the professional foundation every technician must have before touching a vehicle. Students learn to identify hazards, control risk, and correctly select, use, and maintain all categories of workshop tooling — from basic hand tools through to precision measuring and diagnostic instruments. Completing this module first ensures every subsequent practical task is performed safely and to industry standards.

If you're reading this, you're probably at one of a few crossroads. Maybe you've finished trade school and you're wondering what a real, structured pathway forward actually looks like. Maybe you're an apprentice who's learning on the job but suspects there are gaps in your knowledge that could cost you later. Maybe you're switching careers and you want to do this properly — not just pick up fragments of skill, but build genuine, verified competency from the ground up.
I've been on the workshop floor for a long time, and I can tell you exactly what separates the technicians who plateau from the ones who become genuinely indispensable: it's not raw talent. It's systematic knowledge. It's understanding the why behind every procedure — why the combustion cycle behaves the way it does under load, why a specific wiring fault produces that exact symptom on a CAN-bus network, why ADAS calibration has to be performed in a precise sequence. When you understand the why, diagnosis becomes logical. Repairs stick. And you stop second-guessing yourself.
That's what this 12-month diploma is built to do. We go through every major automotive system in the order it matters — starting with workshop safety and precision tool use, because a technician who cuts corners on day one cuts corners everywhere. From there, we work methodically through vehicle servicing, engine internals, drivetrain and chassis, HVAC, electrical systems, and structured diagnostics. Each unit builds directly on the last. Nothing is skipped because it seemed too basic, and nothing is rushed because it seemed too complex.
The final two units — ADAS and Electric & Hybrid Vehicles — are where this program sets you apart. These are the systems that modern workshops are struggling to staff for right now. We cover high-voltage safety and isolation in full, EV and hybrid powertrain architecture, battery management, regenerative braking, and both static and dynamic ADAS calibration using OEM-level scan tools. You won't just have heard of these technologies — you'll be able to work on them, safely and correctly.
I designed this program for the technician I wished I'd had proper structured training to become earlier in my career. Every module is written to treat you as the professional you're working towards being — precise terminology, real diagnostic logic, and the kind of workshop-floor energy that keeps you engaged from the first safety briefing to the final EV servicing assessment. Come in ready to work, and leave ready to work anywhere.
The industry needs technically excellent, adaptable mechanics more than it ever has. This diploma is your pathway to becoming one.
