How Do I Apply for the STS Certification Exam?

Those who are interested in taking the STS certification exam must apply to BCSP, which will determine their eligibility. Candidates need to provide their contact information, training information, experience information, an application agreement and validation of the payment of the application.

BCSP will select, at random, 5 percent of the applications to fully audit and those selected will have to provide their training and experience documentation.

There is a one-year eligibility period during which candidates can pay for their STS certification exam through the BCSP website or a certification services phone number. Candidates are authorized to take the exam on the day that it is purchased up until they have passed the exam or their one-year eligibility period ends.

Candidates can extend their eligibility time limit once during their term and this extension remains valid for one year.

How Is the STS Certification Exam Administered?

The STS certification exam is a computer-based test administered by Pearson VUE at testing locations throughout the world. A tutorial will be provided at the beginning of the exam so that candidates can familiarize themselves with the computer-delivered process.

Candidates can schedule their own breaks during the exam, which must be taken outside of the testing room but inside of the testing building. It is recommended that candidates arrive early for the exam, as those who are 15 minutes late or more will not be permitted to enter the exam room. Candidates must bring a valid, government-issued identification.

BCSP allows calculators in its exams. Examinations are closed book and candidates cannot reference outside materials during the test.

How Is the Content on the STS Certification Exam Divided?

Candidates for the STS certification exam are allowed two hours to complete it. The exam consists of 100 multiple-choice items, each with four possible answers and only one correct answer.

What Score Do I Need to Pass the STS Certification Exam?

All candidates for the STS certification exam are measured against a single minimum passing score. This score is based on the total possible score for the exam, so candidates don’t have to achieve a minimum score in each individual domain. Though all scored items have the same weighting.

BCSP uses the “Modified Angoff Method” to set its passing scores, which is a method that asks a panel of experts to individually rate each examination item against the requirements for a minimally-qualified candidate. It is meant to create a minimum passing score that is based on the aggregated difficulty of each test item.

Candidates will be given a pass/fail result upon completion of the STS certification exam at the testing facility. Those who pass will not receive their results. Those who fail will be given their results so that they can utilize them to better prepare for retaking the exam.

How Can I Get a Passing Score on the STS Certification Exam?

In order to pass the STS certification exam and prepare for a career focused on workplace health and safety, candidates must spend considerable time drilling on the vast material that appears on the test. The easiest and most efficient way to do so is to utilize Mometrix Test Preparation’s available flashcards and study guide, made specifically to provide success on the STS certification exam.
