I have taught primary school for several years, then went back to uni to get a masters and now have applied for a job as head of that subject in a high school. I spoke to the head teacher before applying and he said that the leadership requirements of the job were minor and what he was really looking for was passion and expertise in the subject (I suspect the leadership is a bit tacked on in order to raise the wage a little as it is a very shortage subject area). I have been called for interview, and have been told I have to teach a lesson (obviously) but also that there will be a "worked task". Any ideas what this may consist of?
