I had taught at the boys Junior Section in an international school for 5.5 years and then moved back to Scotland and started supply, long and short term from 2006 to 2008. Since 2008, I could not find further work in my area and had to move to London in 2010. There is a gap of 2 years in my CV (2008-2010) due to unemployment. In London, I worked at a local school to get back into teaching and got register with the supply agencies. I want to get back into independent sector as it suits me and I had wonderful experience teaching in one of them. The school was remarkable institution with excellent results and its pupils were “Best in the world” in Physics and Chemistry declared in the examination of Cambridge. I am currently teaching on daily supply and do not have a headteacher to put in as my first referee. I am applying to independent schools for permanent positions and want to put the director of my supply agency as my first referee as they are the only employer. The director had told me that they had received good feed back from the schools where I had worked through them. Is it ok? What are other options?
