Independent trades exam prep

About CodeSafe

CodeSafe is an independent exam-preparation platform built for apprentices, technicians, tradespeople, and students preparing for licensing and certification exams across Canadian skilled trades.

Our mission is simple: make trade exam prep clearer, more realistic, more affordable, and more focused on understanding than memorizing answers.

Our Story

Built from gas prep, expanded for the trades.

CodeSafe started with gas technician exam prep. The first goal was to create a sharper, more realistic way to practice for G3, G2, and G1 licensing exams.

As the platform grew, the same problem showed up across other skilled trades: students and working tradespeople needed better study tools, clearer explanations, and practice that felt closer to the decisions they would face in real exams.

CodeSafe expanded from that starting point into a broader trades exam-prep platform because tradespeople deserve serious tools that respect their time, their work, and the pressure of certification.

Built for Real Tradespeople

Practice that respects the way trades are learned.

CodeSafe is designed around practical learning, safety principles, field reasoning, repetition, and confidence-building. The goal is not to turn studying into guesswork. The goal is to help users recognize patterns, understand the logic, and review mistakes deeply enough that the next attempt feels stronger.

Practical learning

CodeSafe is built around how tradespeople actually study: repeated practice, clear feedback, and direct connection to the kind of reasoning expected on exam day.

Code and safety logic

The platform emphasizes the reasoning behind answers, including code logic, safety principles, diagnostic thinking, and field-based judgment.

Confidence through repetition

Practice, review, and mock exam flow helps users build familiarity with exam pressure while strengthening weak areas over time.
