In order to be a teacher in about half of U.S. states, you need to pass a Praxis test, or combination of additional tests depending on the state. You will start with the Praxis Core, which measures academic skills in reading, writing and mathematics and consists of:

1. Kaplan Praxis Review

Best for users who like lots of practice questions.

The pricing of their courses is usually comparable to what others charge, so it is generally a safe bet to go with Kaplan.

2. Magoosh Praxis Review

Best for users who want the most bang for their buck. 

What To Expect

Magoosh Praxis is a relatively new test prep service that started in 2008 by students who were getting their MBAs together. The company has grown quickly since then, and now offers test prep courses for a variety of different tests, including the Praxis. If you go to their website you will get an idea of the company and culture, and how it bleeds into their material. Words like agile, swift, and affordable come to mind, but that’s not to say they skimp on their material.

After reviewing the Magoosh Praxis prep course, the feature that stuck out most was that they offer video explanations of each practice question which covers “important concepts, shortcuts, and pitfalls.” This along with their 7 day guarantee, and simple interface make Magoosh a viable option for anyone preparing to take the Praxis.

3. Khan Academy

Best for users who want a free test prep experience. 

What To Expect

“Anyone can learn anything. For free.” Is one of the many slogans on Khan’s website. This non-profit started in 2008 while Samuel Khan was tutoring his cousin in math using Yahoo! Doodle images. Soon his other cousins began using Khan’s instruction so he decided to start posting videos of his lessons online via Youtube. The organization has received sizable donations from companies like Google and AT&T. 

Once you get into the material you will find an overview of each Praxis test section with lessons, along with practice questions and video explanations accompanying each question, similar to Magoosh.

It is also worth noting that Khan Academy Praxis prep is what ETS (the company that administers the test) recommends.

4. Teachers Test Prep

Best for users who want a comprehensive Praxis prep experience.

What To Expect

When we review prep courses, companies like Kaplan always come up because they offer courses for pretty much every kind of test. There are also companies that exist solely for one type of test that they specialize in, and that is exactly what Teachers Test Prep Praxis is. Having served over 250,000 Praxis test-takers as of this writing, Teachers Test Prep is the most robust Praxis prep course that we reviewed. They also have the most options available for test-takers, ranging from free overview study guides and full-length practice tests to live prep classes or even one-on-one tutoring. They boast a 93-98 percent success rate and have instructors from the best universities in the country. 

Course Details

As there are writing, reading, and math sections on the Praxis, Teachers Test Prep offers an individual course for each section, and you can decide how in depth you want to get with each course, as outlined below. 

Teachers Test Prep is also the only course we reviewed that offers prep material beyond the Praxis Core for additional tests you may have to take depending on your state. 

The Most Important Praxis Features: Math Preparation, Materials, and Student Support

Math Preparation

Three of the four prep courses we reviewed placed heavy emphasis on the math section of the Praxis by giving the option to purchase math only review. Because of this, we have concluded that the math section is where test takers have the biggest challenge come test day. Every prep course we reviewed gives you the option to purchase a course that focuses on Math, only, or in the case of the Khan Academy, complete it for free. 


Every course we reviewed offers video instruction, and in some cases, video explanations of practice questions. Each course also has an intuitive interface that is easy to navigate and two of the four courses (Khan and Teachers Test Prep), offer diagnostics where you can take a practice test at the beginning of your studies to see where you need the most improvement.

Student Support

Every course we reviewed offers support except Khan Academy. However, Khan Academy is the only course that is free, so it is up to you, the test taker, to decide what you’re most comfortable with.
