Application Process

The ACE-I application includes one attempt at both of the exams. Passing score is 75% and applicants must pass both exams to become ACE-International certified. If retesting is required applicants must wait at least 30 days from the date of application but not more than one year. Retesting is scheduled via the retesting form. 

All exams are "closed book" and are delivered in a proctored setting. Click here to learn more about exam proctors. Applicants are not allowed to bring notes, books, or smart phones to the exam. The only outside materials which are permitted during the exams are a writing utensil, a single sheet of blank paper (which must be remitted to the exam proctor and destroyed at the end of the exam), and a simple calculator (no programmable calculators or smart phones allowed).

You can take a sample ACE exam. This will give you a better understanding of the types of questions asked and your overall preparedness for the exam. The sample exam can be viewed here:
