I know that the libraries I’ve worked with have very specific policies stating they can’t act in the place of parents and that they aren’t daycares (but they made it sound tactful). However, do librarians have to report kids in the library who they suspect are truant?
LibraryLawBlog answers this question with a resounding “NO!”
Essentially, public librarians are not in loco parentis and have no duty to report suspected truancy.
Of course, this is for Florida, so you should probably check with you library’s attorney if you work in another state. Just trying to be helpful.
