I am a practicing engineer about to make a leap (well, as a snail might see it) into teaching high school math. I've been doing some class observation hours, and right now I believe that my final aspiration is to teach an AP-track math series in a rural or (maybe) inner-city school. That and have some significant summer time to spend :-)
However, I percieve that this will not be a career path that is easy to accomplish in any short order. I expect I will enjoy teaching most math/science courses along the way as I have enjoyed tutoring a wide variety of students, but I doubt I will be satisfied until I am teaching an AP course of some flavor, or moving on to post-secondary roles.
All you out there teaching along the path to AP math... what is your background like? Are opportunities to teach advanced-track courses more a matter of seniority or was something else involved?
Any advice? Anyone think this way when they started, but change focus?
