BenefitsThose 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.
