Certified Commissioning Specialist—CxS Exam Question Bank

Preparing for ACG’s Certified Commissioning Specialist (CxS) exam, formerly the Certified Commissioning Technician (CxT)? This bank gives you five complete mock exams that mirror the real test: 115 multiple-choice questions, 4 hours, closed book, with a 75% pass mark. Every question follows the official CxS exam blueprint and is written as a real-world commissioning scenario. You’ll pick the best next step, the right party or document, or the root cause of a field problem, just as the actual exam asks.

Every question comes with a detailed explanation. It shows why the correct answer is right and why each wrong option fails and cites the relevant section of the ACG Guideline or Standard 202. That way you learn the reasoning, not just the answer.

Exam blueprint coverage

  • Commissioning Deliverables (21%)
  • Commissioning Process, Phases & Approach (33%)
  • Roles & Responsibilities: Commissioning Providers (14%)
  • Roles & Responsibilities: Others (13%)
  • General Construction Process & System Knowledge (19%)

The 5 practice tests

  • Practice Test 1 (1CxS): builds your foundation in the commissioning process, deliverables, roles, and core system knowledge, all at the exam level.
  • Practice Test 2 (2CxS): a fresh set of advanced exam-style questions that deepens your grasp of documentation, field verification, and coordination.
  • Practice Test 3 (3CxS): live case-study commissioning projects. You follow an office tower, a hospital, a data hall, a lab, a school, and a central plant from design review through testing and closeout.
  • Practice Test 4 (4CxS): expert-level technical scenarios across 10 new projects, including an airport terminal, a pharma cleanroom, a district energy plant and a 911 dispatch centre, with two-step calculations.
  • Practice Test 5 (5CxS): a final exam-readiness test across 10 more projects, from a BSL-3 lab and a stadium to a geothermal net-zero HQ and an ammonia cold store.

Key takeaways

  • Understand the full commissioning process, from the owner’s project requirements (OPR) and basis of design (BoD) through design review, construction, acceptance, and the near end-of-warranty review.
  • Know which deliverable to use and when: the Cx Plan, issues log, checklists, functional and integrated system tests, systems manual, training records, and the final Cx report.
  • Tell apart the roles and limits of the commissioning provider, owner, design team, contractors, TAB, and controls teams.
  • Apply field skills: sampling, test readiness, trend reviews, seasonal and deferred testing, and root-cause diagnosis.
  • Solve exam-style calculations without a calculator: airflow, water flow, fan and pump laws, chiller kW per ton, and air change rates.
  • Build exam stamina and timing with full-length 4-hour practice under real exam conditions.

What you get

  • 5 full-length mock exams with 575 unique questions and no repeats across tests
  • Detailed answer explanations with Guideline and Standard 202 references
  • Questions weighted to the official CxS exam blueprint
  • Realistic case studies and field scenarios
  • Timed, auto-graded tests with instant scoring and review
  • Unlimited retakes to track your progress

Who should enroll?

  • Commissioning technicians and early-career commissioning professionals working toward the ACG CxS credential
  • Engineers, field testers, controls, and TAB technicians moving into commissioning
  • Facility managers, contractors, and consultants who want a firm grasp of the commissioning process
  • Professionals preparing for the CxA later on

Benefits of the CxS credential

  • Recognized proof of your commissioning knowledge from ACG, the AABC Commissioning Group
  • A clear path toward the senior Certified Commissioning Authority (CxA) credential
  • Stronger career prospects in new construction, healthcare, data centers, and high-performance buildings
  • Credibility with owners, design teams, and contractors on commissioning projects
