Certification and TRAQ


For in-person certification exams, ISA has issued new exam guidelines beginning May 15, 2020. All exam candidates will receive these in writing once enrolled in an exam.

  • All in-person exams require a candidate to wear a face mask.  A person without a mask will not be permitted to sit for the exam.  The proctor and/or assistant will not be able to provide these for the test candidates.
  • Gloves can be worn but are not mandatory and must be disposed of at the conclusion of the exam in front of the proctor.
  • Candidates are asked to follow a new procedure by answering questions regarding their health and COVID-19 to be admitted into the exam.
  • Wash your hands in the restroom upon arrival at the test site.
  • Review all World Health Organization signage upon arrival.
