Ok, Long story short- I am ambitious and was lucky enough to be promoted to KS4 then HOD within my first two years of Teaching. At one point earlier in the year, I met with my current HT to discuss career steps, after holding HOD post for nearly 5 years. There wasn't anything to offer here currently (3 months ago), but he wanted me to stay, however he did support my applications elsewhere. He did say in this conversation that I was selling myself short applying for HOD jobs elsewhere and should consider AH posts. So I did: got interviews, withdrew from one, and was unsuccessful in another, however this was a good thing as it dawned on me that I simply do not want to leave current school (never about leaving the school, I'd just like new challenges etc.) This was made very clear to current HT and he was fully supportive and I trust him when he says he knows I don't want to leave. Today I have seen a vacancy for AH with a particular specialism at current school. Should I apply for this role? I want to, my heart says yes, but I wonder why it wasn't mentioned to me before if he felt I was ready? He has not contacted me about this advert- it simply went online. Considering he thought I should go for AH roles and my hard work and achievements, I feel I should apply, but I don't want to cut my nose off to spite my face, or make myself look silly if he really doesn't want me. My results have been excellent, observations outstanding, I know I could do the job and would LOVE it (I mean none of that in an arrogant way!) however I'm having a confidence wobble because I'm worried about my age (very late 20s" :O) Thoughts, anyone?
