Yù Rén Resources
A Parent's Guide to Mandarin Immersion by Elizabeth Weise is one of the most comprehensive resources for parents with a child in a Mandarin program. It is a little outdated in places, but a revised edition is in the works. She also has a website called Mandarin Immersion Parents Council, which has news and links to additional resources. There she maintains a list (page link, list link) of schools offering Mandarin Immersion programs around the United States as well as some abroad.
DeepL is used by organizations such as National PTA's DEI group and PTA leaders at schools with complex language communities similar to Harrison Park. It is also the tool Yù Rén & HP PTA use for their communications work.
