CHSOS® Examination Description
The CHSOS® examination is a maximum of two hours in duration unless an extension has been requested and approved. There are 115 questions on the examination. All questions are multiple-choice questions with 4 options from which to select the answer. All questions on the examination must map to at least one of the items in the CHSOS® examination blueprint (pdf).
Scheduling an Exam
SSH does not schedule your examination, the choice of date, time, and location is the responsibility of the candidate.
When the application has been approved, SSH will notify the exam company, ISOQuality Testing, Inc (IQT). The candidate will receive an email from IQT with instructions to schedule the exam. From date of approval and notification, there is 90 days to complete the exam. The candidate should plan to schedule to take the examination during this 90-day period of time.
Examination Day Requirements
Candidates should arrive at the examination location in a timely manner. You may not be permitted to enter if you arrive late. Candidates MUST bring the Admission Letter and a government issued photo identification (e.g. passport, driver’s license) to the examination. The admission letter is emailed to the candidate after registering for the examination.

SSH has worked to add additional locations for testing as appropriate. These locations can be found when selecting your date, time, and location to take the exams (they will appear 90 days ahead of the date of the exams). Additional locations (currently):
ASPE Conference, Portland, OR: June 7, 2020, 0800 start time
SimOps Conference, Greater Cincinnati area, OH: July 15, 2020, 1430 start time
Additional sites will be added as arranged.
IMPORTANT: you must still follow the same application and approval process through the Candidate Management System that is used for the testing sites that are open year-round.
If you need special accommodations to take the exam, these can be requested in the application form (on the appropriate tab).
This INCLUDES if you are requesting extended time due to English being your second language.
The results of the examination are normally available on completion of the exam, either on the screen, or by a printed results sheet (dependent on testing site). Scoring is completed using a scaled score due to the multiple forms used, a 700 is required to pass. Each correct answer is counted towards the total score, there is no penalty for incorrect answers. Each form is equated to provide an equal chance to pass with this 700 score.
Results are either given as Pass or Fail. Passing results have no further information provided (no scale score). Fail results provide both the scale score as well as the percentage of questions answered completely in each domain. This is the only information provided to each individual. No review of individual questions or of the whole exam forms is permitted.
If you were unsuccessful on the CHSE exam, you make take it again. Candidates may take the examination once every 90 days, and no more than four (4) times in a calendar year. Use the information from the previous exam to determine what further study you need.
