New Education Q&A structured data help document from Google

Supported page types. Google said these two page types currently support this type of structured data:

• Flashcard page: A page that contains flashcards that typically have a question on one side and an answer on the other side. To mark up flashcard pages, continue reading this guide to learn how to add Education Q&A schema.
• Single Q&A page: A page that only contains one question and is followed by user-submitted answers. To mark up single Q&A pages, add QAPage markup instead.

Technical requirements. Google listed out these technical requirements for the Education Q&A structured data:

• Put structured data on the most detailed leaf page possible. Don’t add structured data to pages without questions.
• All questions must use the Flashcard value for the eduQuestionType property. Pages that contain other question types are not eligible for the Education Q&A carousel. For pages with other question types, consider using Practice Problems.
• Ensure that your host load settings allow for frequent crawls.
• The questions on your site should be immediately visible to users on the page, meaning that the questions aren’t held only in a data file or PDF.
• If your page has only one question followed by several user-submitted answers, use QAPage markup instead.

English only. This seems to only be available right now for English language queries, Google said the Education Q&A carousel is available in English when searching for education-related topics on desktop and mobile.
