CST Exam Outline

The CST exam contains 175 multiple-choice questions, 25 of which are unscored, and you will be given 4 hours to complete the exam.

The 25 unscored questions are called “pretest” questions, and they are used to evaluate questions for future versions of the exam. You won’t know which questions are pretest questions, as they are mixed in with the scored questions throughout the exam.

The exam is split into three domains.

Test Day

Depending on which testing method you chose during registration, your test day will look a little different.

In-person Testing

You should arrive at the testing center 15-30 minutes before your scheduled appointment time. During the check-in process, you will be asked to provide two forms of valid ID, one of which must contain your photo. Valid forms of ID include your driver’s license, state ID card, passport, and military ID card. If you cannot provide both forms of ID, you will not be permitted to take the exam that day.

Before you enter the testing room, you will be asked to leave all personal items behind, such as books, notes, pencils, weapons, your cell phone, and any valuables.

Once you enter the testing room, you will be given the opportunity to take a practice exam on the computer, which will not take away from the exam time and will not affect your score in any way. This is just to help you become familiar with the computer and the testing software.

Once you have completed the test, you will be provided with a preliminary pass/fail report.

Remote Testing

You should log in to your account 15-30 minutes before the scheduled exam time. Once you have logged in, you will be asked to perform a system check to ensure your equipment and internet connection are adequate.

After the system check is complete, the proctor will verify your identity and ask you to scan your environment with your webcam. Once the proctor is satisfied that you are ready, the exam will begin.

Once you have completed the test, you will be provided with a preliminary pass/fail report.

How the CST Exam is Scored

Regardless of the testing method, you will receive a preliminary pass/fail report as soon as you finish your exam. An official score report will be sent to you approximately 2 weeks after the exam is taken.

To pass the exam, you will need to answer at least 102 of the 150 scored questions correctly.

How to Study for the CST Exam

How to Study Effectively

Your success on CST test day depends not only on how many hours you put into preparing but also on whether you prepared the right way. It’s good to check along the way to see whether your studying is paying off. One of the most effective ways to do this is by taking CST practice tests to evaluate your progress. Practice tests are useful because they show exactly where you need to improve. Every time you take a free Certified Surgical Technologist exam practice test, pay special attention to these three groups of questions:

  • The questions you got wrong
  • The ones you had to guess on, even if you guessed right
  • The ones you found difficult or slow to work through

This will show you exactly what your weak areas are and where you need to devote more study time. Ask yourself why each of these questions gave you trouble. Was it because you didn’t understand the material? Was it because you didn’t remember the vocabulary? Do you need more repetitions on this type of question to build speed and confidence? Dig into those questions and figure out how you can strengthen your weak areas as you go back to review the material.

Answer Explanations

Additionally, many CST practice tests have a section explaining the answer choices. It can be tempting to read the explanation and think that you now have a good understanding of the concept. However, an explanation likely only covers part of the question’s broader context. Even if the explanation makes sense, go back and investigate every concept related to the question until you’re positive you have a thorough understanding.

Comprehend Each Topic

As you go along, keep in mind that the CST practice test is just that: practice. Memorizing these questions and answers will not be very helpful on the actual test because it is unlikely to have any of the same exact questions. If you only know the right answers to the sample questions, you won’t be prepared for the real thing. Study the concepts until you understand them fully, and then you’ll be able to answer any question that shows up on the test.

Strategy for CST Practice

When you’re ready to start taking practice tests, follow this strategy:

  • Remove Limitations. Take the first test with no time constraints and with your notes and Certified Surgical Technologist study guide handy. Take your time and focus on applying the strategies you’ve learned.
  • Time Yourself. Take the second practice test “open book” as well, but set a timer and practice pacing yourself to finish in time.
  • Simulate Test Day. Take any other practice tests as if it were test day. Set a timer and put away your study materials. Sit at a table or desk in a quiet room, imagine yourself at the testing center, and answer questions as quickly and accurately as possible.
  • Keep Practicing. Keep taking practice tests on a regular basis until you run out of practice tests or it’s time for the actual test. Your mind will be ready for the schedule and stress of test day, and you’ll be able to focus on recalling the material you’ve learned.
