Meet our Talent Search winners

Our mission at Khan Academy is a free, world-class education for anyone, anywhere - but we can’t do it alone. To reach more learners and cover more subjects, we need more explainers to create more content.

That’s why we launched the Khan Academy Talent Search this May - to find great explainers and amplify their voices. About 4,000 folks submitted videos to the contest, sharing 8,000 lessons with learners around the world. The quality and creativity of these submissions blew us away!

After reviewing all the entries, we’ve selected 10 promising winners:

Dan Quinn, postdoctoral student in physics
Dara Brady, fifth-grade teacher
David Rheinstrom, editorial director at Leftside RightSide
George Zaidan, freelance science video creator
Grant Sanderson, recent graduate of Stanford University
Guillaume Riesen, doctoral student in neuroscience
James Portnow, video creator at Extra History
Sage Simhon, high school student
Sudhir Murthy, undergraduate student at the University of California, Riverside
Tony St. John, chemistry professor at Western Washington University

Last week, we brought all the winners to California for an immersive workshop on creating videos and cultivating channels. These 10 incredible explainers visited the Khan Academy and YouTube teams and even took a selfie with Sal.


Sound exciting? Although this year’s Talent Search has ended, you can still help us bring more content on more subjects to learners around the world. Check out our careers page for current openings on our content team, or tell us about other YouTube channels and educational websites you think we should know about here.


College students share their experiences with Khan Academy

This spring, Stanford Consulting - a nonprofit, student-run organization - ran a survey to learn about the impact that Khan Academy has had on the educations of current college students. These students were asked whether they “found Khan Academy meaningful to their education” and whether they were the first in their family to go to college. The results are in, and today we’re excited to share some of the key findings.

Of the students who responded to the survey…

- 65% of Stanford students found KA meaningful to their education (out of 504 surveyed)
- 57% of students in other top schools* found KA meaningful to their education (out of 159 surveyed)
- 64% of first-generation college students (the first in their family to go to college) at these schools found KA meaningful to their education (out of 164 surveyed)

*Surveyed schools include Harvard, Princeton, the University of Pennsylvania, UC Berkeley, Caltech, Notre Dame, MIT, Vanderbilt, and Yale.

We’re thrilled to see how many college students have benefited from Khan Academy and to hear their stories. One first-generation student from Stanford shared the following note with us:

For all the times I couldn’t turn to my parents for homework help, I had Khan Academy videos to help me. Khan Academy was the private tutor that my family could not afford. For all the times I wanted to learn for the sake of learning, I would pick from the hundreds of Khan Academy videos.

Can you earn more points than me this summer?

Hi, I’m Cam from Khan Academy, and I challenge you to join me for a surge of summer learning!


I can’t unicycle yet, but I’m learning. My other summer learning goals are focused around biology and economics.

No matter what you choose to learn on Khan Academy, you’ll be eligible to earn two special badges:

  • Get the Summer Surge badge by earning at least 50,000 energy points this summer.

  • Get the I Beat Cam badge by earning more points than I do this summer.

The challenge runs from the June 23rd through August 28th (official rules below). There’s no special signup to earn these badges; all you have to do is start learning now!

Not sure what you want to learn this summer? Here are three ideas:

  1. Supercharge your math skills. For example, if you’re headed into Algebra I, jump into the Algebra I mission and get started on those mission foundations (pre-requisites) to make sure you start the school year strong!

  2. Join Pamela in a Summer of Scripting! Sign up for reminders and weekly contests to help you learn JavaScript, one of the world’s most popular and important programming languages!

  3. Explore a new topic you’ve always been curious about, such as economics, finance, art history, or health and medicine. Remember: You can learn anything!

I look forward to learning alongside you this summer. You can track my summer learning progress by watching my KA profile or by following me @icamlearn on Instagram or Twitter. Let me know what you’re learning using the hashtag #KASummerSurge.

Your fellow learner,


Official rules

All points earned anytime from the very start of the day (PDT) on June 23rd to 11:59pm PDT on August 28th will count towards these badges.

Badges (described above) will be awarded only after the contest has ended. I’ll give everyone their badges on August 31st.

Who is beating me so far?

I have earned a total of 0 points so far this summer (as of June 23rd), so I imagine lots of people are beating me right now. But, remember, badges are awarded at the end of the summer (after August 28th), and you’ll only get the “I Beat Cam” badge if you earn more points than I do over the course of the entire summer.

Check back here in coming weeks to see a list of usernames that are beating me.

UPDATE (July 16th): Because so many of you have earned so many points, I’ve decided not to post a list of everyone beating me - it would fill up the entire screen! Instead, here are instructions for how to figure out if you’re beating me:

Step 1: Calculate your starting points (points earned since June 23rd).

  1. Go to your activity page (profile–>progress–>activity).
  2. Set a custom range to see your progress since the 23rd.
  3. Sum your daily energy points to find your summer earnings.
  4. Subtract your earnings from your current KA energy points to find your starting points.

Step 2: Spin of this awesome CS program and input your starting points.

Step 3: Watch the program calculate whether or not you’re beating me :-)
