Praxis® Math Content Knowledge Practice Test

What Is the Praxis Math Content Knowledge Exam?

If you have decided to take the journey to become an educator, the certification process can seem overwhelming, as each state institution and organization has unique requirements. Most states require one or more Praxis tests for teachers based on the grade level and subject you will be teaching. If you have decided to follow a mathematics route in secondary education, your state or institution may require you to take the Praxis Math Content Knowledge 5161 test. The average tester has completed a bachelor's degree with an emphasis in mathematics and possesses a general understanding and ability to apply mathematical concepts to solve problems.

Practice tests give you a better idea of the topics you have mastered and those you should keep studying.

Praxis 5161 Exam Overview

The Praxis 2 math test (Praxis 5161) is composed of two content categories with a total of 60 questions. It is a computer-delivered exam with questions formatted as selected-response (multiple-choice, numeric entry, text completion and drag-and-drop). You will have 150 minutes to complete the Praxis math content knowledge exam. On some questions, you will have access to an on-screen graphing calculator. The table below will give you an overview of the sections on the test, the approximate number of questions, and the weight of the questions on your exam.

Taking the Praxis Math Content Knowledge Exam

Once you have determined that Praxis 5161 is the correct test for your certification, you can begin your Praxis test preparation and think about what happens after you have completed the Praxis test. The first step is to register for the Praxis 2 math content knowledge test, so you will have a timeline of studying and a set testing day. Then, you can begin exploring study materials, getting a baseline of what you already know and what you need to know. Finally, you will take your exam and wait to receive your scores/have your scores sent to the agency or institution (s) of your choice. We'll cover these steps in detail below.

Registering for the Praxis 5161

You can begin the test registration process by ensuring you are signing up for the exam needed to meet your certification requirements, looking at the testing locations available, finding Praxis 5161 test dates, and familiarizing yourself with Praxis test fees. The Praxis 5161 fee is $130, and both in-person and at-home testing locations are available. If you would like to take Praxis at home, you must reside in the United States and meet equipment and environment requirements. You can search for an in-person testing center near you on the ETS website.

After deciding where you would like to take your test, you can create a free account and proceed with Praxis online registration. Alternatively, you can register by mail or by phone. There is a $35 processing fee when registering by phone.

Praxis 5161 Test Prep

Studying for a test, especially one that directly affects your certification, can be intimidating. Luckily there are several resources available to help you study and perform your best on the Praxis math content knowledge test. A step in the right direction is taking a 5161 practice test. Praxis practice exams measure your current knowledge and give you a baseline for what you need to study on. To optimize your time, you can strategically study first what you do not know, and closer to the test, refresh your memory on the things you already know.

Praxis Math Content Knowledge Test Prep Materials

A great resource and starting place is a study guide or study companion that provides in-depth information on what is included in the exam, question format, and even Praxis 5161 practice test questions. Another useful test prep resource is a practice test that models the testing environment and gives you an in-depth explanation of each answer. It is recommended to take this test closer to your Praxis test day in order to get a good representation of how you will do on the test.

Praxis 5161 Test Day Preparation

You have made it to the day of the test! What to expect can vary based on whether or not you registered for an in-person or at-home examination.

In-Person Exams

If you are taking the exam in person, remember to bring your:

  • Admissions ticket
  • Valid photo ID
  • A calculator (if allowed and not provided on your test)

Do not bring personal items, as you will not be allowed to use them during the test or breaks. Avoid wearing jewelry, glasses, or other accessories that you do not need. Clothing is subject to be searched. It is recommended to arrive at the Praxis testing center 30 minutes prior to the exam. Once you arrive, the test administrator will check you in and show you your assigned seating. Most tests do not have scheduled breaks, although a 5-10 minute unscheduled bathroom break is permitted; the testing clock will not stop during an unscheduled break.

At-Home Exams

If you are taking the exam online, make sure your environment meets the requirements of a clear, well-lit, private space. Run a final equipment check and ensure all issues are fixed prior to the start time. Then, gather your:

  • Valid photo ID
  • Appropriate note-taking materials (erasable whiteboard or cellophane sheet)
  • Cell phone or handheld mirror for check-in

Make sure your clothing is appropriate, your ears are visible, and you are not wearing jewelry/glasses/accessories that could be used to cheat. It is recommended that you log on 15 minutes prior to the start of the Praxis exam. You will check in by showing the proctor a 360-degree view of the room you are testing in and utilizing the cellphone or mirror to provide a view of your computer screen. The proctor will authenticate your identity, read you the rules, and begin your test. During the Praxis test, do not communicate with anyone except your proctor. Scheduled breaks are normally not included, but an unscheduled 5-10 minute restroom break is permitted, although your testing clock will not stop.

Praxis Math Content Knowledge Passing Score

Praxis exams are graded by taking the raw points you earn on each question and transitioning them into a 100-200 point scale based on the difficulty of the test. On this scale, 100 is equal to 0% and 200 is equal to 100%.

Each state institution or agency has the ability to create the standards of certification, thus the passing Praxis score for your state may differ from someone in another state. The range of praxis 2 math passing scores is between 135-160 with 160 being the most common. On the ETS website, there is a helpful tool where you can input the test you took or your state/agency to see the passing score for your area.
