The ScratchJr app has been translated into 6 languages with the help of volunteering ScratchJr Translators from all over the world. If you have experience with a language, you can help the ScratchJr Team and other translators in completing translations for new languages and correcting any mistakes in current translations.

Translating the ScratchJr App and Website

The ScratchJr app and website are translated using Transifex. It lets registered translators suggest and edit the translations. The submitted translations are licensed under The MIT License


To translate part of ScratchJr app or website, you have to submit a translation application form first. You will be asked to provide the following information:

  • Name
  • Email
  • Languages
  • Translation experience
  • Reasons for interest in translation

When you submit the form, the ScratchJr Team will review your application and send you a Welcome Email that contains an invitation to the translation projects and a welcome package with details and information. Please refer to the Code of Conduct for the ScratchJr translator community.


After creating an account and logging in, you can start translating! In the dashboard on your account page, you can choose, from your personal list of projects, what to start translating.

Click Translate. You will be taken to the translation page. Choose the language you want to translate to and the resource you want to start translating.

What to translate first

Start with the ScratchJr app project. When the translation of the app is complete, you can start translating the ScratchJr website, then the ScratchJr videos.

When starting a new translation, always begin with the glossary. In the right pane, choose Glossary, then View Glossary. In the glossary page, provide translations for the terms. When the glossary translation is complete, proceed to translate the terms in the left pane.

Previewing translation

Changes on the site can be previews before publishing to the main site. A new version of the ScratchJr website has been added for that purpose at The new content can be viewed in context using Transifex on that version of the site at to see the new content in context.

Offline translation

We recommend that you translate directly on transifex, as it provides suggestions from others and warns of possible errors. However, if you prefer, you can translate offline.

Start by clicking the languages tab under the project being translated from your personal list in the Dashboard. Choose the language you want to translate to, then click Translate.

In the popup window, click on Download for translation as XLIFF. The file contains the current strings to be translated. You can open the file and edit it using a text editor. (What are the next steps?)

When you're done, you can upload through the same popup window. Make sure to choose the Upload XLIFF file option for the upload.

Publication of new languages

The ScratchJr team publishes a new version of the ScratchJr app every 3–6 months. This is when new languages are added to the app. In order for a new language to be added to the app, its translation condition in Transifex should be as follows at the time of publication:

  • ScratchJr app: Translation 100% complete.
  • ScratchJr website: Translation 80% complete / Index page translation 100% complete.

Languages that do not fulfill these criteria will not be included in the publication.

Note: Once a new language is published, it is expected that the status of translation is sustained for both he app and website after publication. A of 90% status of translation of the Teach and Learn pages on the website should be maintained at all times.
