Schools and Teachers LOVE CodeHS!

You ALL are GREAT! The best support ever! I am telling all my friends who teach at area high schools to use CodeHS for their programming courses!

Anne Marie Bette

Teacher, New Egypt High School

My freshmen absolutely love computer programming. They rush in and get started way before the bell rings and keep going after the dismissal bell.

Bruce Supalla

Teacher, Helena Christian School

I can't thank the CodeHS team enough for being so patient and helpful to me when I was taking the PD course. They went above and beyond, giving me extra help and offering practical classroom tips that I plan on using when I teach the course this coming school year. The PD is well worth it!

Found out a former student who did CodeHS and then went on to programming in college tested out of his intro course.

Teacher, Greater Lisbon Christian Academy

The web site and program have revolutionized how we are teaching computers.

Mark Gasaway

Teacher, Covenant Christian Academy

I love it, the kids love it.

Brian Smith

Teacher, North Star Academy

CodeHS has been a game-changer in my Intro to Programming class for 9th graders. The students have been much more engaged and motivated since we started using CodeHS

Tom Simpson

Teacher, Heathwood Hall Episcopal School

My students love it! They are engaged, they can work at their own pace. It's awesome!

Courtney Moore

Teacher, Battle Mountain High School

I *love* CodeHS! It took me a little while how to figure out how to effectively use the FastGrade & Filter & Canned Responses, but now I have mastered it, and I'm catching up on my grading, and the students are getting much more timely feedback from me. I love how most of the feedback is automatically generated by the system. Bravo, CodeHS!!!

Charles Olson

Teacher, Mills High School

Loved it I loved it! Fantastic! I'm in love with the program's y'all have, thanks!



Its AWESOME. The kids love it.

George Toothman

Teacher, Saint Thomas Choir School

The students say the class is "fun, fun, fun" and that the class period is too short.

Ellen Kohrs

Teacher, Sea Crest School

Teaching computer science has ignited my passion for the subject. CodeHS has been a big part of that.

Christopher Evans

Teacher, Arlington Classics Academy Middle School

Bottom line: This class is the talk of the school. Kids are all working independently without any instruction from me. They are watching the videos and learning from mistakes. Discovery learning at its best. Very, very cool!

Teacher, The American School of Tangier

codeHS is flexible for both students and teachers, because I LOVE the problem-solving approach and puzzle/game nature of the exercises, and because students can learn at a level that is appropriate for them - whether they are a slow first-timer or speedy and already have coding experience. And it's all packaged in one place - CodeHS.

Eric Ferrante

Teacher, Cupertino High School

It was sort of like the Animation and Graphics module was the "event horizon" for capable students to get pulled into the "black hole" of programming awesomeness.

Don Gamble

Teacher, St. Ignatius Preparatory School

I've been extremely pleased with my CodeHS experience. My favorite part is the grading feature. My students have completed 10x as many labs and received 100x better feedback via CodeHS versus any other textbook or platform I have used in the past

Timothy Hipp

Teacher, Woodward Academy

It's out of this world compared to Code School and Codecademy. Keep it up! ;)


Student, Duanesburg Central School

Ok [my students] just asked me to stay later to do more coding. Later than the 1241 normal dismissal... My class is dying to build the helicopter game.

Joe Thompson

Teacher, Gunston High School

CodeHS offers a very easy platform for beginner programming teachers and provides a simple curriculum any teacher can use "right out of the box." I have taken on the humbling role of being a "lead learner" and am so thankful for the resources CodeHS provides.

Linda Hahn

Teacher, The King's Academy

We love the program, students love the programs, parents love the program, it's been exceptional!

Tyler Groth

Teacher, TechyKids

I am LOVING CodeHS!!!

Charles Olson

Teacher, Mills High School

Thanks so much, Max! I LOVE working with CodeHS, and have recommended it to other educators in the district. Hopefully I will be supported in gaining some more professional development funding if I'm asked to continue to teach a course on coding.

Sarah Shirk

Teacher, Da Vinci Institute

WOW!!! The students LOVED Karel the Dog! Today was their first day of using the software and the curriculum. Every single student was engaged and the comments were so full of excitement. This is going to be the much needed shot in the arm that my students need, I can tell already!

Linda Brown

Teacher, Desert Hills High School

I am really enjoying CodeHS. FYI - everyone keeps saying - why not use Khan Academy or code academy? ... And I keep telling them CodeHS has the materials to support the teacher and the class!

Roger Crowe

Teacher, James F. Byrnes Freshman Academy

The classes are amazing!! Kids really seem to be focused and engaged in the activities.

Nick Yugo

Teacher, North Star Academy

I want to thank you and all of CodeHS for providing such an awesome program (pun intended) of studies for my students. My favorite comment from one of my students was: "Wow, we REALLY learned a lot this year, and it was fun!" Another student said, "I never thought that I would be able to do something like this, but look at my works and I did it all by myself!"

Eve Sarra

Teacher, Central High School

First of all, my students are absolutely loving this class. They are flying through the Karel module. Take a look. We've had two 87 min classes so far and some of my students have completed activities that I had on my syllabus for Sept. 24. It has been amazing.

Jerome Schmidt

Teacher, Brentwood High School

The program has been improving each year and the addition of Cybersecurity makes CodeHS a cut above the rest!

Rik Fujioka

Teacher, Murrieta Mesa High

CodeHS is one of the best, no, scrap that. It IS the BEST of the computer programming websites on the internet. I would sincerely tell this to a friend to learn coding. You never know when it could come in handy.



I will praise codeHS to the skies and tell them why its better than codecademy, udacity, udemy, cousera, or books

Joe Thompson

Teacher, Gunston High School

It is AWESOME I LOVE IT. It is really interesting. I sat at my computer 3 hrs. straight and couldn't get my eyes off of it until my parents told me it was enough. . THANKS FOR MAKING CODE HS!!!


Student, Girls Teaching Girls to Code

I used CodeHS to teach JavaScript earlier this school year with my high school intro to programming students (mostly freshman & sophomores). In short, they loved it! The software was excellent. CodeHS is age-appropriate and engaging. Students were excited to come to class everyday & would start working on their programs before the bell would ring...The instructional model was great with short videos to introduce new programming concepts followed up with programming challenges.

Kristen Fisher

Teacher, Township High School

Thanks again for your excellent work in building CodeHS into the best online resource for teaching programmatic thinking and CS problem solving at the high school level. There is no resource that comes remotely close to what CodeHS provides.

Eric Ferrante

Teacher, Cupertino High School

My students learned so much more than coding through your wonderful program. Many of them will never write a line of code again, but they learned perseverence, precision, problem solving, cooperation and collaboration (you should have seen them analyzing and debugging each other's programs). These and many other "real world" skills, that they learned during their adventure in coding, will serve them well throughout their lives and in their chosen careers.

Eve Sarra

Teacher, Central High School

I truly believe the site is the most interactive way to teach programming!

Seth Nilson

Teacher, Sentinel Peak High School

I have been using CodeHS for 4 years and love the curriculum!

Paige Daniels

Teacher, High Point Christian Academy

This is a perfect step by step on-line tutorial. Short focused lessons. Clear videos. Good sample problems. Good auto grading. Quick responses from tutors. Excellent suggestions from tutors. Easy to use interface. Excellent progress reporting. HELP very helpful. Easy to stop and then return where left off. DOC'S helpful and easy to use. I love it when my problems turn green and I get a "Well done" response from a tutor. Easy to test and de-bug programs. So far it's free.

John Sawyer

Teacher, Lanika Elementary School

I have been using CodeHS in the classroom for over a year now. It has been an immense help to me, and overall it's an excellent product with a myriad of uses and a ton of content

Zach Huffman

Teacher, Busan Foreign School

Karel coding education is awesome!! It's easy and kind to learn!



I think you've built a really great website that gives a lot of help and support, but at the same time is challenging. I've used many of the other popular websites that have beginning coding material (Khan Academy, Codecademy, Code School, etc.) and yours is by far the best. I love learning (and hopefully teaching!) on here.

Jennifer Gyles-Bedford

Teacher, West Chicago Community High School

Not only is the tutorial age-appropriate and accessible, the things you choose to teach and how you teach them are Right with a capital R. I stand up and applaud the pedagogy. Well done!

Stephen Nucia

Software Engineer

CodeHS was so easy to work with. Assigning and grading work was a breeze; both my students and I could track their progress with the "colored dots", without any effort at all. We all loved the short videos. They were just the right size chunk of information for the students to digest at one time; anything longer and they would have tuned out. Then they were off to the example programs and the part they liked best: the hands on programming.

Eve Sarra

Teacher, Central High School

I had 101 students take the AP exam, and 95 passed with a 3 or better (~94% pass rate). It is great to be able to know that we are providing them with such solid content throughout the year through the use of CodeHS!

Sean Raser

Teacher, California High School

We come in and the students start working on their code. We are self paced and they start where they left off from the last class. Some students that are further along will assist others in writing or solving the code problem. It is great to see peer review and assistance. The students are teaching each other. I have set milestones to check progress, but students seem to breeze by these most of the time. I usually have to tell the students it is time to go at the end of class, because they want to stay and finish.

Mark Gasaway

Teacher, Covenant Christian Academy

I just forwarded the link to one of my colleagues - an engineer and currently a math teacher at Cape. She is very interested - she brought her lowest level Algebra class into the Achievement Center (my place) and we had her class do the hour of code challenge. She was blown away by how engaged her kids were. She actually teared up she was so happy! She is very interested but hasn't done coding in years - I told her go to boot camp and with the codeHS materials - you will be ready to go! I also told her you were my online mentor and did a great job so I know the boot camp will be great.

Ginger Raspiller

Teacher, Cape Elizabeth High School

CodeHS is the best learning platform of its kind. I've tried many sites in the last year or so and they don't come close in terms of engagement and challenge. It's the the best bar none.



FYI: Our kids at Clinton Hill started using CodeHS last week and are hooked; you guys have a really great product.
