I'm a recent graduate and decided to spend a year subbing to gain more in-classroom experience before going after a full-year position. I received a call from my district's sub-caller, asking me if I'd be interested in a Long Term Position for High School English (which is basically my dream job for the moment). I had the interview today, but after asking to see my resume and CEAS and telling me that there was a senior class in addition to the sophomore ones, she had me asking all the questions and said that while I seemed well-prepared (I had a huge portfolio of stuff I did student teaching as well as a list of questions prepared), she's concerned about me teaching a senior class because of my age. I know to take certain precautions-- like always leaving the door open, never being alone with a student, etc-- and she did say that everyone had to go through it eventually. Do you think being a young teacher (I'm 21, but I look even younger) will negatively impact my chances of getting the job? Or have any advice for young teachers/subs that could help me have a more successful interview in the future?
