My associate (signed up this past fall) told me to make sure my bio was "not a repetition of what the reader will find on your resume and application, but to [use] the opportunity to bring yourself to life for the reader." Actually talk about you and reveal a little about yourself. I wrote about what I like to spend my time doing outside of work and how that, in turn, helps me to be a better teacher.

But, at the end of the day, I am not certain my bio helped get me an interview or not. I have a feeling that, like many college application essays, it has more to do with your ability to write well rather than what you say.
