CHST Exam Eligibility

Before you can begin the registration process, you’ll need to rack up at least 3 years of experience working in construction safety, health, and environment.

What’s on the Exam?

Questions: 200
Time limit: 4 hours

First, let’s talk about the questions on the exam. There are 200 multiple-choice questions total, but about 25 of the questions will count toward your score. Why is that?

Unscored Questions
The unscored questions on the CHST exam are called “beta” questions. These are added to the exam to determine if they’re good enough questions to add to future versions of the test.

The trick is that you won’t have any way of knowing which questions are scored and which ones are beta. They will appear just like the scored questions throughout the test.

The time limit for the exam is 4 hours. There aren’t any scheduled breaks, but you’re free to take restroom breaks as needed.

Exam Scores

The exam is scored using two methods: the modified Angoff method and the bookmark standard setting method.

Modified Angoff Method
This method relies on a group of subject matter experts to evaluate each question on the exam and determine its overall difficulty. Once a rating is agreed upon for each question, they establish a cut score, which indicates how many questions you need to answer correctly to be at the minimum level of competency.

Bookmark Standard Setting Method
This method relies on a group of subject matter experts to evaluate each question on the exam one at a time. The goal is to find a single question that represents the minimum level of knowledge/ability required to be a competent CHST (in some cases, they may decide there are multiple “bookmark” questions).

To pass the exam, you’ll need to answer at least 140 questions correctly.

Retaking the Exam

If you didn’t get a passing score on your first try, that’s okay! You can retake the test as many times as you’d like. Just note that there’s a mandatory six-week waiting period between attempts.
