1. Apply through the City of Minneapolis: Start by submitting the required competency card application to the City.
2. Receive eligibility approval to test: After your application is reviewed and approved, your eligibility is communicated so you can move forward with exam scheduling.
3. Schedule your exam through the ICC testing system: Minneapolis contractor/trades exams are administered through ICC with scheduling and test centers provided by Pearson VUE.
4. Study from the correct references: Build both knowledge and open-book speed using the books tied to the exam’s content outline.
5. Pass the exam and complete remaining city steps: After passing, follow the City’s instructions for any remaining administrative steps to obtain your master competency card.

At the master level, the exam is designed to reflect supervision-ready knowledge. That means the questions often resemble real job decisions: installation choices, equipment and piping considerations, safety devices, and system performance outcomes.

State Requirements

Minnesota’s mechanical and fuel gas standards shape how steam and hydronic systems are installed and maintained, and the City of Minneapolis requires competency cards for masters and journeymen in specific trades. For master steam & hot water candidates, the practical expectation is that you can do more than follow directions—you can evaluate a system, confirm compliance, and supervise work so installations are consistent, safe, and inspection-ready.

In real-world terms, master-level requirements show up as professional expectations:

• Code-aligned installation decisions that support safe operation and proper system performance.
• Correct component application so valves, fittings, accessories, and safety devices are selected and installed with intent.
• System-level troubleshooting so you can diagnose issues using steam/hydronic fundamentals, not guesswork.
• Controls understanding so you can confirm that systems respond correctly under normal operation and fault conditions.

Test Information and Study Materials

The best way to prepare for ICC 775 MN-MI is to study like a master: focus on the highest-weighted categories, connect code requirements to field outcomes, and build your ability to confirm details quickly. Below is a practical guide for each content area and how to use your references effectively.

General (25%)
This category rewards candidates who understand the “big picture” of steam and hydronic work: terminology, basic principles, and code awareness. Treat General as a scoring opportunity. Build comfort with definitions, system components, and how requirements are organized. When questions are broad, the correct answer is often the one that matches how systems actually operate and how code language is structured. Use your Minnesota Mechanical and Fuel Gas Code to reinforce general provisions and foundational requirements that influence installation and compliance decisions.

Piping and Equipment Installation (20%)
This is where master-level thinking stands out. Expect questions that feel like the job: how equipment is connected, what installation choices matter, and how to recognize correct vs. incorrect practice. Strong prep here means understanding the reasons behind installation requirements—serviceability, safety, performance, and proper operation. Use your codebook for requirement-driven questions and your HVAC Systems & Equipment reference to reinforce how equipment and systems function in the real world.

Pipes, Valves, Fittings, Accessories (10%)
These questions test whether you can “think in components.” Valves and accessories aren’t just parts—they control flow, protect equipment, enable maintenance, and support safe operation. Study this category by learning function first and verifying details as needed. When you can clearly explain what a component does and why it matters in a steam or hot water system, the questions become far easier to answer accurately.

Hydronics (Hot Water & Chilled Water) (15%)
Hydronic knowledge includes distribution concepts, common components, and how systems behave under load. Focus on circulation logic, system balance thinking, and how equipment choices affect performance. Use the HVAC handbook to reinforce system concepts and the code reference to confirm the requirements that affect installation and compliance. A master-level approach means you can recognize the “why” behind a correct answer: protection, performance, and predictable system behavior.

Steam (20%)
Steam is a major portion of the exam and a major responsibility on the job. Strong steam prep includes steam fundamentals, system behavior, and safety-focused understanding—how pressure, temperature, condensate, and distribution work together. Use your Low Pressure Boilers reference to strengthen your steam foundation, then reinforce your ability to confirm requirements quickly when code language is involved. Many steam questions can be answered confidently when you understand the system logic and the purpose of safety devices and controls.

Controls (10%)
Controls questions often test applied knowledge: what a control is meant to do, what it monitors, and how the system should respond. This category is especially important for master-level candidates because controls are where safety and performance intersect. Study controls with a “cause and effect” mindset—what condition is being detected, what action occurs, and what result that action is meant to produce. When you can trace the logic, you can answer faster and with more certainty.

Study plan that matches the exam:

• Start with the biggest scoring buckets: General (25%), Steam (20%), and Piping & Equipment Installation (20%).
• Reinforce system understanding: Use Low Pressure Boilers and the HVAC handbook to make concepts feel familiar and job-realistic.
• Build open-book speed: Practice finding answers quickly using the index and table of contents—especially for installation and component questions.
• Review missed questions by reference location: When you miss a question, learn where the correct information lives so you get faster next time.

Exam-day pacing tip: With 100 questions in 3 hours, you have an average of about 1.8 minutes per question. That pace is achievable when you can quickly identify which reference to use and where to look. Your prep should train that decision-making so you’re not wasting time flipping between books without a plan.
