Who is theCoderSchool

Code Coaching®

Code Coaching® is our core philosophy, and what our school is all about!  We believe that every student is different, and that kids should learn in the way that works best for each child. How? Our Code Coaches® - they're the magic sauce!  Unlike some coding schools, we don't just leave the kids in front of a computer, expecting the software to teach them how to code. Nor do we force all kids to go through the same curriculum or projects, regardless of their skills and interests. Instead, our Code Coaches® customize their lessons for each child, and focus on a 2 on 1 mentee-mentor relationship with our kids so our students can get the focused attention they need.

Code Coaching® works for kids of all ages and skill levels, from novice to advanced. From game development to web apps, Python to Java, or even niche technologies like AI and beyond, our Coaches can help your kids achieve their goals.

Sessions run one or two hours a week (your choice), at the same time every week on a schedule that works for both you and our assigned Coach. Check out our video for more info!

Coding Lessons for Kids in West County, MO

Coding takes practice, and we believe getting kids to code consistently throughout the year is the only way they'll really learn to code! That's where our Code Coaches® come in, providing a long-term mentoring relationship to teach kids to code, from someone who's a coder themselves.

Our coding school's flagship program, Code Coaching®, combines a super-small teaching ratio of typically 2:1 or 1:1 with individualized curriculum so kids are able to move at their own pace, doing things that interest them most. This program works for kids of all ages and skill levels. From game development to web apps, Python to Java, or even niche technologies like AI and beyond, our Code Coaches can help your kids achieve their programming goals. Sessions run one or two hours a week (your choice), at the same time every week on a schedule that works for both you and our assigned Coach. Our lessons are taught in-person at our schools where available, or can be online for social distancing. Fill out our form above to get a free trial today!

Our Coder Tree®

We believe that every student learns in his or her own way, not only in what they want to work on, but how fast and how much. Our Coder Tree® is a visualization of our students' learning options as they grow and a sampling of some of the topics we teach. Like real trees, our students' coding journeys are unique from each other, but all require strong foundations and trunks to support their higher, advanced branches. Need a magnifying glass? Here's a zoomable view.

Tracking Progress

Custom coding means tracking progress is even more important! Our suite of proprietary tools* does just that. Our Coder Progress and Notes+ systems chart weekly progress through concept tracking and freeform notes. App Reviews track longer term progress by identifying current skills to build their individual Coder Tree®. Finally, our Student Portal is a one-stop shop to see it all and then some! Confused? It's complicated! Get an idea by clicking through a Sample Student's functional Student Portal to see for yourself.

Summer Camps

While St. Louis county has stated that the stay-at-home orders will be lifted on May 18th, we still feel that there is a lot of uncertainty and hence are canceling in- person summer camps at least in the month of June. We will hold remote camps depending on enrollments.

At West County, we have been working very successfully with remote coaching in our weekly year round after school program since mid-March. We have accumulated excellent experience thanks to the support of our parent community!


Here are a few testimonials:

  • “My son has been taking class at The Coder School since they opened and we were concerned we would have to stop during this pandemic. We were so pleased that the Coder School was able to accommodate classes and still be able to conduct "normal" coding class! It certainly provides a sense of normalcy during this chaotic time.”

  • “The Coder School has been a wonderful addition to my daughter's learning. It is impressive how much she has learned from her weekly coaching sessions. When COVID hit and our "new normal" caused most everything to go virtual, the Coder School was able to transition to the virtual environment seamlessly. Our online coaching sessions via Zoom have been an effective alternative to the in person sessions. My daughter continues to enjoy her classes and her ability to interact with her coach has not been hindered. Because coding is one of her passions, I am pleased that we've been able to keep up with this through this crisis!”

  • “Remote Coaching has been great for my son. It has allowed him the opportunity to stay connected to his amazing teacher and he is continuing to learn valuable coding skills. This is a great distraction from the boredom of being stuck at home.”

  • You will receive that same experience in our remote summer camps. This time, our ratio will be 6:1 or less depending on enrollment. Our Online Summer Camps will be conducted on the platform of Zoom and will be a mix of a week-long coding project, mini lessons, coding challenges, Kahoot! quizzes, tech talks, small group collaborations with breakout rooms, interactive games, exercise, screen-free breaks and of course, the chance to present their projects to fellow campers on the last day of camp!

    The camp timings will be from 9:30-2:00 with a one hour lunch break in between. We will coach from 9:30-11:30 and then resume again from 12:30-2:00. The camp cost is $199.


    Campers will be required to have the following technology available at home:

  • Windows PC, Apple/Mac, or Chromebook (or similar) computer.
  • Internet connection of at least 15 Mbps (most homes support at least this speed)
  • Microphone/Speakers - Many computers have a built-in microphone/speaker system that should work
  • A video/web camera connected to your computer allows us to see your child and coach them better based on their reactions.

  • Our sister schools have piloted three weeks of Online Camps during Spring Break and received rave reviews from families!

    Beyond Camps: Our year-round program weekly builds upon their summer experience. Coding Camp is like learning baseball over the summer. You must keep building on those skills throughout the year, you cannot just drop it.

    If you have any questions, we would be happy to offer you a free trial lesson! Please email at charu@thecoderschool.com or you can call at 636-220-3002 to chat!

    Our Schools

    Meet Our Owner and GM

    Charu Katyal

    Hi, I am Charu Katyal and I am the General Manager and co-owner at The Coder School. Most of my work experience has been in HR and IT recruitment, and my volunteer experience is primarily in the realm of education whether it is causes that support underprivileged kids or volunteering at my daughter’s school. These arenas that are seemingly separate, blend together in The Coder School mission which is: to teach children coding in a fun, nurturing environment. Truly an intermeshing of education and HRD which can be summed up as, "Kids learning happily!" That they are, because the teaching is customized and paced according to a child’s strengths and interests.

    In today's STEM focused environment, The Coder School is a perfect fit. When kids learn programming they hone many skills-logic, precision, reasoning, problem-solving, persistence and much, much more as they evolve into creative out-of-the-box thinkers. Our school lights a spark that is limited to not only coding, but one that carries over to math and science and beyond. So many of us assume we are not good in math, and it is my passion that children not borrow the same script. When kids learn to code they are learning math and science too as they organize data, break it down into smaller components, analyze, use math expressions and algorithms as they advance forward. For all of this to happen, the building block is an environment which is conducive to experimenting and taking risks. Welcome to a new experience...The Coder School! Please contact me at charu@thecoderschool.com.

    Meet Our Co-Owner

    Kathy Kilo-Peterson

    My name is Kathy Kilo Peterson and I am co-owner of The Coder School, Chesterfield/Town & Country. I am a parent that is passionate about enriching the lives of children. My business partner, Charu Katyal, will be running the school on a daily basis. I will be in the background helping with community outreach. I am super excited to bring The Coder School to St. Louis. We have such a rich connection to the Founders, Hansel Lynn and Wayne Teng. Both are Silicon Valley guys that attended Washington University, returned to Silicon Valley, met and founded The Coder School. They are just as excited as we are to bring this approach of learning technology to St. Louis. What I love about teaching kids to code, is that they learn logical thinking and math while having a blast. The ability to code is a skill every child should have. The philosophy of the Coder School intertwines technology learning, critical thinking and presentation skills. These skillsets will continue to become increasingly important for our children. Feel free to contact me directly at kathy@thecoderschool.com

    Meet Our Code Coaches® Too!
