I took a head 4A gig after one year of teaching.
I would strongly recommend, as someone who's been in your shoes, to wait a little longer before taking the head job. It is a LOT more than you think it is. Perhaps you're the next Kathy Johnson Randy Jones, or Amanda Drinkwater, but even they did not take a head gig one year out of the gate. They learned, and so should you.
If you don't selected don't take it personally. They wouldn't put a 2nd year teacher as the head athletic director either.
