When you work as a teacher, it can be a very competitive field. Looking for a new job is never going to be easy, as lots of people will apply and you will face lots of competition when going for interviews. One of the best things you can do is to make sure you have an up to date CV.
Even if you are not looking for a new teaching job, keep your CV updated just to be on the safe side and save yourself time. When you do decide to move on from your current position, your CV being up date will make such a difference. It won’t take very long to do if you don’t have that much work to do on it. You may want to consider uploading your CV online, even if you are not actively job hunting. You may end up being headhunted for a better role.
