How can I get into teen librarianship?

If you're an IUPUI LIS student, as I am, then there are several relevant courses to take.  There is a course plan offered for those who would like to specialize in Youth Services, and here are its required courses:

S571 is what it sounds like--this course will help you learn how to assess materials for children's and teen's departments.  S572 is the essential course, focusing on "the history, philosophy, and description of children and young adult library services."  According to the class description, it will also help evaluate programming and other services offered, and how to anticipate future trends in youth services.  S672 is the advanced seminar, that will cover a variety of topics, depending on the semester.  It can cover anything from minority issues to collection evaluation to poverty.

Teen librarians may of course work in schools, but if you're going to be in a public library, then a good class might also be S575, Public Library Services.

Internships can also be a great way to get experience.  In searching around for internships, I found several that were public libraries co-operating with local universities.  Here's one such example for the Sunderland Public Libraries in Massachusetts.  IUPUI also offers the chance of internships through course S605 for more advanced students--those who already have 18 credit hours under their belt.  You can get an application here after speaking with some possible sponsors.

YALSA (remember--ALA's Youth Services portion!) also has tips for finding volunteer spots if you just want a more casual experience, or don't have the time to commit to something more.  They recommend these following sites for finding volunteer opportunities:
