I took some time to evaluate and make some decisions about my professional future (oh, and I got married, completed my National Boards, and bought a house in the meantime). After looking at school administration and various other career paths, I decided to pursue my MLIS. To be honest, my initial goal was not to be a school librarian. I actually intended to become an academic librarian.
I took the classes for academic librarianship and avoided the classes for school libraries like the plague. Then as I was finishing up, I decided I should go ahead and take the classes for school library certification just in case. Boy, that turned out to be a great move. Our school librarian was taking a year off for maternity leave, so I asked to take that position during her absence. That was the best thing that ever happened to me. She actually ended up not returning, and I stayed for ten years in the position.
Being a school librarian has been one of the most rewarding experiences. My evolution as a professional started when I took that position. I was lucky to have supportive administrators, and I am so thankful for all the students and teachers I had the opportunity to work with over the years.
