Guidelines for creating and submitting tutorials and lessons for Hour of Code™ and Computer Science Education Week hosts a variety of Hour of Code™ activities, lessons, and videos on the and Hour of Code websites. The current list is at

Want to submit your own self-guided tutorial, teacher-led lesson, or robotics/maker activity that explains a computer science principle? Join this global movement and help participants around the world get started with an hour of code or go further with multi-lesson, day-long, or week-long activities.

After reading the guidelines, you can submit your activity through our Hour of Code™ Activity and AI Submission page. You can submit an activity at any time, but the deadline for inclusion in any given calendar year is October 1 for non-AI activities and for 2023, if you are working on an AI submission, the deadline is anytime between now and October 31st. For clarity, any activities received after October 1, 2023 for non-AI or October 31, 2023 for AI, will not be listed for 2023's Hour of Code. If you have any questions about your activity submission, please reach out to us at

A few tips:

  1. Submit more than one activity: If you’ve built activities for different levels, different ages, or other categories, we list your activities separately so each teacher can find the right thing for their classroom. Submit each tutorial or activity individually. Given the number of submissions we have seen in recent years, we will have time to review up to 5 activities per partner. After that, we will make a best effort to review as many as possible before Hour of Code begins.

  2. Beyond beginner lessons: In addition to lessons for teachers and students who are learning computer science for the first time, we list learning experiences for computer science-savvy classrooms that want to go a little bit further! Help us by submitting lessons for classes that are already comfortable with the basics.

  3. Subject areas: Have a great lesson idea that integrates Computer Science into Math? History? Language Arts? Science? Art? Or another subject? We’ve had numerous requests from teachers who want to connect the Hour of Code to their subject area. Teachers can filter for their classroom type (grade band or subject area) so we need your help filling in gaps to offer classroom activities or lesson plans that relate CS to every major subject area for different grade bands. We also continue to have a “Computer Science” category for teachers who are looking for generic CS activities.


What to submit

Self-guided puzzle or game (example)

These activities are designed for students to self-direct through a tutorial. They don’t require much instruction from a teacher or teacher prep work.

Teacher Facilitated lesson (example, template)

Now that hundreds of thousands of educators have tried the Hour of Code, many classrooms are ready for more creative activities that teach the basics of computer science. To help more advanced teachers find inspiration, we collect and curate "teacher-led" lessons and activity plans for Hour of Code veterans.

One type of activity that we will feature for experienced teachers are “open sandbox” creation projects. Activities that encourage students to build their own app, game, website or other project. If facilitated properly, more open-ended activities can better showcase the creative nature of computer science.

Some educators may also prefer to host Hour of Code activities that follow a traditional lesson format rather than a guided-puzzle/game experience.

You can start with this template for your lesson plan.

Activities for teachers in other subjects/fields

We also feature lesson plans designed for different subject areas. For example, a one-hour lesson plan for teaching code in a geometry class. Or a mad-lib exercise for English class. Or a creative quiz-creation activity for history class. These can help recruit teachers in other subject areas to guide an Hour of Code activity that is unique to their field, while demonstrating how CS can influence and enhance many different subject areas.


For students with special needs

If you create an activity or tutorial that is designed for special needs students, please call that out in the description. In particular, there are very few options for the vision-impaired. If your activity is designed for this audience, please let us know.

General guidelines for creating an Hour of Code activity

The goal of an Hour of Code is to give beginners an accessible first taste of computer science or programming. The tone should be that:

The activities should teach a computer science concept such as loops, conditionals, encryption, or how the Internet works. An activity can also teach about how computer science connects to real world occupations, events, or history. For example, teaching UX design to make apps that are meaningful for an audience or cause. We discourage activities that focus on the syntax of programming rather than the concepts. For example, we will list, but not highlight, activities that teach HTML. Similarly, we discourage block programming lessons that focus on setting/changing configuration options rather than learning how to model an algorithm or process.

Technical requirements: Because of the wide variety of school and classroom technology setups, the best activities are Web-based or smartphone-friendly, or otherwise unplugged-style activities that teach computer science concepts without the use of a computer (see Activities that require an app-install, desktop app, or game-console experiences are okay but not ideal. We will not list activities that require sign up or payment. (Robotics activities can require robotics purchase.)

Student-led (Self-Guided) Format: The original Hour of Code was built mostly on the success of self-guided tutorials or lessons, optionally facilitated by the teacher. There are plenty of existing options, but if you want to create a new one, these activities should be designed so they can be fun for a student working alone, or in a classroom whose teacher has minimal prep or CS background. They should provide directions for students as opposed to an open-ended hour-long challenge. Ideally, the instructions and tutorials are integrated directly into the programming platform, to avoid switching tabs or windows between the tutorial and the programming platform.

How activities will be evaluated

For 2023: AI submissions will have an evaluation process separate from the base coding activities submissions. AI submission will be evaluated based upon level of engagement, creativity, and opportunities for participants to learn about AI.

For traditional coding activities, a diverse committee of computer science educators will rank submissions based on qualitative and quantitative criteria. All activities that fit the basic criteria will be listed. Teachers will be able to filter and sort to find the best activities for their classroom.

The rubric for evaluating activities and lesson plans will look for the following criteria on all activities and rank them accordingly:

If the review committee rates the activity a zero in production quality (due to bad bugs or instructions that make it very hard to use), in promoting learning in underrepresented groups (due to racist/sexist material), in educational value (does not teach CS concepts), or fun/engaging (due to being difficult/discouraging for students to work through), the activity will not be listed.

In addition, in order to be listed, all activities must:

For self-directed activities for new teachers and students the review committee will be looking for whether:

Teachers and students will be able to search through and filter our list of activities based on filters such as grade, experience level, subject, hardware, etc. By default, we will show lesson plans and activities first that:

Suggestions for designing one hour self guided tutorials

Activities do not have to include AI, though we are looking to offer more AI related activities.

You can include the Hour of Code logo in your tutorial, but this is not required. If you use the Hour of Code logo, see the trademark guidelines below. Under no circumstances can the logo and name be used. Both are trademarked, and can’t be co-mingled with a 3rd party brand name without express written permission.

Make sure that the average student can finish comfortably in an hour. Consider adding an open-ended activity at the end for students who move more quickly through the lesson. Remember that most kids will be absolute beginners to computer science and coding.

Include teacher notes. Most activities should be student-directed, but if an activity is facilitated or managed by a teacher, please include clear and simple directions for the teacher in the form of teacher-notes at a separate URL submitted with your activity. Not only are the students novices, some of the teachers are as well. Include info such as:

Incorporate feedback at the end of the activity. (E.g. “You finished 10 levels and learned about loops! Great job!”)

Encourage students to post to social media (where appropriate) when they've finished. For example “I’ve done an Hour of Code with ________ Have you? #HourOfCode” or “I’ve done an #HourOfCode as a part of #CSEdWeek. Have you? @Scratch.” Use the hashtag #HourOfCode (with capital letters H, O, C)

Create your activity in Spanish or in other languages besides English.

Explain or connect the activity to a socially significant context. Computer programming becomes a superpower when students see how it can change the world for the better!

Make sure your tutorial can be used in a Pair Programming paradigm. This is particularly useful for the Hour of Code because many classrooms do not have 1:1 hardware for all students.

Trademark Guidelines

Hour of Code® and Hora del Código® are registered trademarks of Many of our tutorial partners have used our "Hour of Code" trademarks on their web sites in connection with their Hour of Code activities. We don't want to prevent this usage, but we want to make sure the usage falls within a few limits:

  1. Use “Hour of Code” only in connection with non-commercial CS Education activities in the context of the Hour of Code campaign, and for no other purpose.
  2. Any reference to "Hour of Code" should be used in a fashion that doesn't suggest that it's your own brand name, but that it rather references the Hour of Code as a grassroots movement. Good example: "Participate in the Hour of Code ® at". Bad example: "Try Hour of Code by ACME Corp".
  3. Use a “®” superscript in the most prominent places you mention "Hour of Code", both on your web site and in app descriptions.
  4. Include language on the page (or in the footer), including links to the Hour of Code, CSEdWeek and web sites, that discloses both the following: a. Hour of Code® and Hora del Código® are registered trademarks of; and b. “The 'Hour of Code ® is a nationwide initiative by to introduce millions of students to one hour of computer science and computer programming.”
  5. Do not use "Hour of Code" in app names.
  6. Do not use “Hour of Code” in connection with any commercial use or purpose (e.g., placing your Hour of Code activity behind a paywall; promoting another paid service as part of your Hour of Code activity; selling Hour of Code merchandise).
  7. Do not use “Hour of Code” in connection with any activity that requires a login or account creation.

Tracking Pixel

In order to more accurately track participation we ask every tutorial partner to include a 1-pixel tracking image on the first page of their Hour of Code tutorials. The pixel-image must be on the start page only. Do not include on any interim pages of your tutorial.

This will allow us to count users who do your Hour of Code tutorial. It will lead to more accurate participation counts for your tutorial.

If your tutorial is approved and included on the final tutorial page, will provide you with a unique tracking pixel for you to integrate into your tutorial. See example below.

NOTE: this isn't important to do for installable apps (iOS/Android apps, or desktop-install apps)

Example tracking pixels for Dance Party:
