Passing & Certification

Each specialty certification exam must be taken separately and passed. To obtain all certifications, you must test in all specialties.

An overall score of 70% or higher is required to pass the certification exam. If you don't pass, the areas of study/categories with a score of 65% or less will be provided for your preparation to retest. The areas of study reported reflect scores based on the number of questions in each category/section of the exam.

Maintaining your certification will require Continuing Education Units (CEUs). For CEU requirements please see our CEU Information page.
