Quick Facts

  • The Industry Competency Exam (ICE) is an entry-level exam that is supported and validated by the major industry associations.
  • There are three exams: Residential A/C and Heating, Light Commercial A/C and Heating, and Commercial Refrigeration.
  • Candidates taking the Commercial Refrigeration exam are also encouraged to take the Residential or Light Commercial A/C and Heating exam because the same applications are covered, but with different equipment.
  • Each test has 100 multiple-choice questions, and you must score a 60% or above to pass.
  • Over 300 schools require students to take the exam before graduation.
  • Each test costs $30 to take.
  • If a candidate fails the exam, s/he may take it again.

  • Benefits

    Those who pass the exam will receive an individual score report and a certificate/wallet card of competency. They will also have their names published in a major trade magazine, and if desired, their names will be placed in a national job bank. Those passing the test also have the opportunity to purchase shoulder patches that say they are ICE certified.

    Why Should You Take The ICE Exam?

    Because the ICE exam is industry recognized, it will give you a boost in job placement. Individuals who pass the ICE test will have an edge in the job market because it shows that they know what the industry says entry-level technicians should know.

    Taking the exam will also give you the opportunity to measure your skill level. You can determine what you have mastered and what you need to work on.
