Every teacher aspires to work in a good school where they can thrive, move up through the ranks and progress in their careers. Working in a top school helps things along and can providing a better environment for progressing in your career. It can be harder to get a job in a very good school in the first place though, with competition being stiff. Landing a job of this calibre is a very big achievement for any teacher.
The first step is knowing where to find the current teaching job opportunities in your area. Teaching job boards and recruitment agencies can tell you about some of the best positions around and can help you apply for them as well, based on your experience and teaching job history. They will know what the school is looking for so can provide tailored support while you are getting your application ready and are deciding how to sell yourself to the school.
