With 70 questions in 3 hours, you do not have time to “learn by searching” during the exam. The goal is to understand the topic first, then use the books to confirm the detail and move on.

Open-book habits that help you perform:

• Know which book answers which question type: Mechanical code for Minnesota requirements, ASHRAE 15 for safety and system requirements, ASHRAE 34 for refrigerant designations/classifications, and the refrigeration textbooks for applied system understanding.
• Practice index lookups: Speed comes from choosing the right term and going straight to the right section.
• Use “find-and-confirm”: Start with your best answer, then confirm it in the book instead of searching from scratch.
• Train with time pressure: Run timed sessions so your pace feels normal on exam day.

Licensing Steps

Minneapolis uses a Certificate of Competency card system for certain trades, including refrigeration. The exam is a key step in proving qualification. While individual situations can vary, journeyman candidates commonly follow a process like this:

1. Confirm the credential you need: Identify whether your scope of work in Minneapolis requires the Journeyman Refrigeration competency card.
2. Submit the City application: Apply through the Minneapolis competency card process and provide the required documentation for review.
3. Receive eligibility approval: Once approved, you’ll be authorized to take the exam for a set period of time.
4. Schedule the ICC exam: The Contractor/Trades exam is administered through ICC’s computer-based testing partner.
5. Study with the correct references: Build both refrigeration knowledge and open-book navigation speed using the approved references.
6. Pass the exam and complete remaining city requirements: After a passing score, follow the City’s instructions for final steps to obtain your journeyman competency card.

Journeyman certification signals you can perform refrigeration work with consistent trade competence—system understanding, safe practice, and code/standard awareness that supports compliant installations and service.

State Requirements

Minnesota’s mechanical standards influence how refrigeration systems are installed and serviced, and Minneapolis adds the competency card requirement for certain trades working inside the city.

Test Information and Study Materials

The ICC 768 (MN-MI) exam is designed to test applied refrigeration knowledge—how systems work, how they’re installed and serviced safely, and how standards and code references support correct decisions. The most effective prep is to study by the blueprint and build “job-real” understanding.

ACR (40%)
This is your biggest scoring category, and it includes the fundamentals you use every day: the refrigeration cycle, heat transfer concepts, pressure/temperature relationships, superheat and subcooling awareness, and how components function together. Use your refrigeration textbooks to strengthen system understanding and troubleshooting logic, then use the code/standards references to confirm details when the questions require a requirement-based answer.

Commercial Refrigeration Systems (26%)
Commercial systems bring additional complexity—larger equipment, application-specific system choices, and stronger safety expectations. Focus on system types and how they’re used, common commercial components, and how controls and protection devices support stable operation. This category is also where safety standards become practical: understanding why requirements exist helps you choose correct answers faster.

Refrigeration Gases (15%)
This section rewards candidates who are comfortable with refrigerant designation and classification concepts. ASHRAE 34 is the key reference for refrigerant naming and classification. Study with a “what does this mean in practice?” mindset: classification knowledge supports safe application, correct equipment decisions, and professional awareness that shows up in both testing and real work.

Controls (10%)
Controls questions often test cause-and-effect thinking: what is being sensed, what action occurs, and what outcome that action is meant to produce. Focus on the purpose of common controls and safety devices and how they protect the system. When you can trace system logic, controls questions become far more predictable.

Piping, Tubing, and Related Equipment (9%)
Even though this is a smaller section, it can be a strong scoring opportunity because many items are detail-based. Focus on correct application and professional workmanship knowledge: tubing and piping concepts, fittings and connections, related equipment, and how installation choices affect system reliability. Use your textbooks to reinforce practical understanding and your code/standards references to confirm requirement-driven details when needed.

Open-book pacing strategy for a 70-question, 3-hour exam:

• Prioritize first-pass accuracy: Answer the questions you know immediately, then use the books for confirmation where needed.
• Limit deep searching: If a lookup is taking too long, mark the question and return later if time allows.
• Build a repeatable lookup method: Index → section heading → confirm the detail → move on.
• Study with the books open: Train the exact skill the exam rewards—fast location of correct information.

How to structure your study week: Spend most of your time on ACR and Commercial Refrigeration Systems first. Then add focused sessions on Refrigeration Gases (ASHRAE 34) and Controls. Finish your week with mixed timed drills where you practice switching between references without losing pace.
