Test design

The STS certification exam contains 100 multiple-choice questions. Each question is followed by four possible answers with only one correct response. If a formula is required to determine the solution, it is embedded into the question.

Questions are developed from the following five domains:

  • Safety program implementation – 13.8%

Knowledge and skills assessed in this 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.

  • Hazard identification and control – 47.1%

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 – 9.2%

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.

  • Leadership, communication, and training – 18.4%

This domain evaluates your knowledge and skills with the Code of Ethics, conflict resolution techniques, safety observations, training requirements, effective communication, effective coaching and mentoring, corrective actions, motivational techniques, negative reinforcement techniques and application, chain of command, management of worker limitations and accommodations, and identification of relevant compliance aspects.

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!
