A little background.. I interviewed with District 1 last week and received a call from AP that they will recommend me to the board and I basically have the job. I am not sure what subjects I will be teaching but it will probably be high school Biology or Chemistry. This will be at a 5A school and a little more 'inner city' but the pay is good-ish. This week, I interviewed with District 2 and they told me it is for a Physics position. I told the P that I am not very comfortable teaching Physics but I will do my best if given the job. This is a 3A school farther out in the country and pays ~10K less than District 1. However, this P is now talking to my references and seems very interested and I suspect he will offer me the job. I am waiting to sign a contract with District 1, and I feel bad for P at District 2. Should I email the P at District 2 and let him know that I probably will not accept the job if he offered it to me? Or wait till I have a definite contract with District 1? What if the P from district 2 offers me a contract before District 1? Thanks for any advice!
