Hi, Leaving after 1 year never used to be particularly frowned upon, but now the job market is so much more competitive it could be an issue. The important thing is that you make it very clear, obvious and understandable why you want to move schools. The start date of your current job will certainly stand out on your application and be flagged up - but if you are a really great candidate, then the panel will just want reassurance that there's nothing wrong/something dodgy hasn't happened. Explain the PULL factor - how you just couldn't miss the opportunity at this school / a school you've wanted to work in for a long time etc - and also by a convincing explanation of why your skills/knowledge/experience aren't being utilised in your current post. I was employed in my current school after being only 2 terms in my previous school - my Head said to me that she went on the (previous) school's website and said she "immediately understood how out of context" I was there (not quite sure what that says about me but it worked and she offered me the job...) Good luck.
