Helping aspiring teachers reach higher with new Official Praxis® Core Prep

Teachers and students are the heart of all that we do at Khan Academy. That’s why it was a no-brainer for us to partner with ETS,  the makers of the Praxis® exams, to help aspiring teachers enter the profession. Our new Khan Academy Official Praxis® Core Prep is a free, first-of-its-kind preparation resource which is now available for tomorrow’s educators.

Aspiring teachers can use Official Praxis® Core Prep to create a personalized learning plan to prepare for the Praxis® Core Academic Skills for Educators (Core) test, a key exam for many candidates entering teacher preparation programs. Using Official Praxis® Core Prep can strengthen the reading, writing, and math skills needed to succeed on the Praxis® Core test, in teacher preparation programs, and in the classroom.  

“There are a lot of resources out there that say they will help you, but they are expensive and you never know if they will really help,” said Vivica Foster, an aspiring teacher in Ohio who was part of the Official Praxis® Core Prep beta test. “Not only is it amazing that this program is free, but the number and variety of practice questions available really tested my knowledge and prepared me for test day."          

Together, Khan Academy and ETS hope to widen the path to teacher preparation programs and help diversify the teacher pipeline. A recent study by the National Bureau of Economic Research underscores the importance of diversifying the pool of teachers. The study shows that having a Black teacher increases Black students’ high school graduation rates and likelihood of enrolling in college.                 

Official Praxis® Core Prep diagnoses teacher candidate’s strengths and weaknesses. Each learner then receives a personalized study plan to remediate skill gaps and help them succeed on test day. Official Praxis® Core Prep guides teacher candidates through a series of in-depth instructional materials—including practice questions, videos, and tips—that meet their unique needs. The program focuses on key subject matter areas and takes into consideration the time available to study for the test.

Khan Academy has a proven track record of leveling the playing field by providing access to high-quality test prep resources. Official Praxis® Core Prep is Khan Academy’s third free and official test prep program for high-stakes standardized exams. In 2015, Khan Academy launched Official SAT Practice with the College Board. Research shows this resource has driven substantial SAT score improvements regardless of gender, family income, race, or ethnicity with similar usage rates across demographics. In 2018 Khan Academy launched Official LSAT Prep, which is being used by more and more by aspiring law students, particularly African Americans, women, and economically disadvantaged students.

Announcing Our New Partnership with NWEA to Accelerate Student Learning

Teachers have long told us they want more actionable insights into the assessments they give every year in their classrooms to improve learning for every student.

That’s why we’re excited to announce that Khan Academy is partnering with NWEA, a mission-driven education nonprofit and maker of the gold-standard classroom assessment, MAP Growth.

Together we’re developing MAP Accelerator, a unique classroom tool designed to help teachers deeply integrate personalized learning and assessment to accelerate student achievement.

Watch our announcement video: 

MAP Accelerator will help teachers quickly and easily deliver a personalized learning path for every student based on their MAP Growth results. Teachers will be able to identify which students need extra help to fill gaps and unleash learning for students who are ready to move ahead.  Teachers can use MAP Accelerator to differentiate instruction for students with diverse academic needs, particularly traditionally underserved students.

“If I had to pick between an amazing teacher and amazing technology, I’d pick the teacher every time. That is why we wanted to build a tool that really empowers teachers. Partnering with NWEA takes our tools and resources for teachers to the next level,“ said Sal Khan, founder of Khan Academy. "We’ve long heard from teachers who want to use MAP Growth as more than just a benchmark. Now teachers are able to inform personalized practice that integrates with any curriculum so they can help focus student learning on what is needed most. And it is simple and time-saving, which is super important since teachers already have so much on their plates.”

This fall, more than 150,000 students in four school districts will use MAP Accelerator as part of a limited pilot program. The districts include Madera Unified School District, Pajaro Valley Unified School District, and Glendale Unified School District in California; and Clark County School District in Nevada.

During the pilot year, MAP Accelerator will be available for grades 3-8 in math, English, and Spanish. English-language arts will be introduced the following school year when MAP Accelerator becomes universally available.

Old School, New School: Mastery-Based Learning

By Beatrice, a guest blogger who is a junior in high school

The high school I attend in Silicon Valley requires all juniors to spend one week participating in an internship or shadow week. I was lucky to be able to spend my week at Khan Academy.  During my shadow week, I learned how Khan Academy reaches people all over the world who are driven to deepen their education. It was also a chance to attend communications team meetings, learn about the testimonial process, and understand how press release requests are handled. Throughout the week, I also realized that Khan Academy, Khan Lab School and the Waldorf school that I attend share the belief that students understand concepts best through mastery-based learning—an educational pedagogy that allows students to learn at a pace that is suitable to them.


At first glance, it might seem surprising that an online learning experience like Khan Academy, a startup like Khan Lab School, and a Waldorf school that has roots in a philosophy that goes back nearly 100 years would have anything in common. (Waldorf schools are based on the teaching principles of Rudolf Steiner and were founded in the early 20th century.) Noticing the common thread of mastery came as a complete surprise during my shadow week. While there are many differences among the three organizations, mastery-based learning is an approach they share.  

At Khan Academy, over 200 team members are dedicated to providing learners all over the world with a free, world class education. Students, whether they are in classrooms or working independently, can go as fast or as slow as they want, and mastery is central to the way students learn and advance their understanding of Khan Academy subjects.

At Khan Lab School, mastery-based learning frequently occurs in blended or project-based environments. This approach advances the idea that students working in a self-paced setting will fully master concepts and skills. In many schools, the time students spent learning is constant and the level of content mastery varies. The opposite is true at Khan Lab School.  The amount of time it takes to learn something can be variable and everyone eventually achieves a mastery level understanding of each subject area. I also learned that students use Khan Academy at Khan Lab School, especially for math and computer science.

At Waldorf, mastery is neither blended or online, and our use of technology in high school classes is lower than at other schools. The Waldorf philosophy is based on the idea that a student’s natural desire to learn is unleashed in an environment where they are seen, feel safe, and have an opportunity to undertake hands-on work. I feel that the interdisciplinary and multimodal approach combined with the ability to resubmit work until it is mastered has given me agency over my learning, critical thinking skills, and a sense of empathy. At Waldorf, I have learned that it is not the academic skills that matter most but rather the ability to learn how to learn. Interestingly, Khan Lab School has a similar philosophy.

During my shadow week at Khan Academy, I learned that there are many different facets to the operational side of an educational organization. Shadowing Barb and Rachel from Khan Academy’s communications team gave me a feel for what they’re trying to get across to students, teachers, districts, and the wider world. One way they do this is by communicating with the media and arranging interviews for Sal, Khan Academy’s founder, and other members of the Khan Academy team. I enjoyed having a front row seat to this one area of Khan Academy.  

One last thing I’d like to share is that Khan Academy reaches 18 million learners a month in 190 countries in over 30 languages as a nonprofit. I personally know of many students who would not be able to use Khan Academy if they had to pay a subscription fee. During my shadow week, I encountered even more students around the world whose lives have been changed significantly by Khan Academy. Because it is a nonprofit, Khan Academy depends on donations from individuals to help sustain the work they are doing now and the work they need to do in the future. For me, it has been heartening to learn how individuals have been impacted around the world through access to Khan Academy. Onward!

Khan Academy students make it work in new documentary series

At Phillips Magnet Elementary School in Napa, California, where 65% of students are second-language learners and 85% come from low-income backgrounds, one group of students is bringing light to a community no longer willing to stay in the shadows.

Watch the trailer:

The new docuseries ‘Make it Work’, now available on Amazon Prime Video and The Roku Channel, features students who are inspired by their teacher and powered by lessons from Khan Academy. Follow their journey as they apply newfound skills to propose a public improvement project to make the streets around their school safer.

“I’m so proud of these students,” says Sal Khan, Khan Academy’s founder. “Their success shows us how students who have access to a high-quality education are able to unlock their full potential and accomplish great things. I want that for every child in America and around the world.”

Narrated by YouTube icon Hank Green and produced and directed by Emmy Award-winning filmmakers Kip and Kern Konwiser—‘Miss Evers’ Boys’ and ‘On Hallowed Ground’—the four-part series follows young disruptors as they use imagination and innovation to improve their communities.


Sal joins the Cult of Pedagogy podcast to discuss mastery!

We’ve heard so many good things from Khan Academy teachers about the Cult of Pedagogy podcast and the teacher tools and resources found on its site that we had to get involved! Recently, Sal joined the podcast to discuss how our new mastery learning system can make a big difference in classrooms, the importance of teachers in unlocking the potential in every student, and why Khan Academy’s nonprofit status is more important than ever.
