Test design

The STS certification exam contains 100 multiple-choice

domain include job safety, hazard analysis, auditing, inspection protocols,
inspection requirements, investigation techniques, waste management, work and
cross-functional hazards, changing conditions, communication, and violations.

The skills and knowledge assessed in this
domain include hierarchy of controls, classification and labeling, energy
isolation procedures, handling and storing of hazardous materials, safety
systems, pressurized systems, confined space requirements, industrial equipment
and tools, certifications for heavy equipment, hazard control, safety
operations, personal protection, safe work practices, ergonomics, motor vehicle
operation, technology, and compressed gas storage.

  • Health hazards and basic industrial hygiene –

Your knowledge of chronic and acute health
hazards, hearing conservation, and environmental conditions are assessed in
this domain.

  • Emergency preparedness and management – 11.5%

Preparedness and management including fire
protection methods and classifications, fire safety requirements, emergency
response plans and drills, basic first aid, cardiopulmonary resuscitation,
automated external defibrillator, and universal safety precautions.

worker limitations and accommodations, and identification of relevant

The STS exam has a time limit for two hours, and you are
allowed to use a personal calculator as long as it meets the requirements
listed on the website. If you do not have an approved calculator, an on-screen
calculator is available for your use.

Test day

On the day of your exam, report to the testing center 15 to
30 minutes before your appointment. An early arrival gives you time to find
parking, secure your gear, and complete the pre-test activities. Your
identification is verified, and a test administrator escorts you to your
testing station. The exam is closed-book, and scratch paper is provided to you
at your station.

Before your time begins, you can take a short
familiarization tutorial. After you complete the tutorial, your exam begins.
Take care to answer every question, even if you have to guess. Immediately upon
completion of the exam, your status is reported to you. There are two possible
results – pass or fail.

Score report

Before you leave the testing center, your score report is provided. If you passed the exam, no other information is provided. If you did not pass, diagnostic information for each domain is provided. Of the 100 questions on the exam, 13 are used for validation and do not count toward your score. To pass the STS certification exam, you need to answer 61 questions correctly.

How Can I Prepare for the STS Test?

That’s a great question.  We’ve broken down the answer into three parts.

  1. Do yourself a favor and study.  Do not walk in unprepared. We have recommended prep materials below, but that only helps if you actually try.  Plus, studying is actually proven to be the best antidote to test anxiety.
  2. Take care of yourself.  Make sure you’re eating well, exercising, and sleeping.  All of these things are scientifically linked to brain performance.  If you take care of your body, you’ll be helping your grades.
  3. Get a study guide or set of flashcards.  Some people study better a certain way. Find your study strengths and make the most of them.  We’ve tried to make it easy for you by tracking down the best study guide and flashcard set for your exam. Below you’ll see links to both!
