Is it possible for someone to participate in more than one reading challenge using Beanstack?

Yes, readers may participate in more than one challenge at a time. Readers will be invited to register for all challenges available based on their age or grade level. They can then toggle between different challenges to check progress in them.

If you have more than one challenge available for the same age group/ grade level, and want the reader to choose between the challenges, then you will enable alternative challenges. For more information, read this article.
