Sorry Robby, times they are a-changing. You do have a time limit to complete your NQT year. AND once you start you have to complete it within two years. If you don't, your qualification will be invalid and you would have to do your ITT again to be able to teach in the UK. I'd agree with the others. Get NQT done first. Keep your options open. Plus, as someone said, the good schools want two years' experience. And would you want a school that didn't care if its teachers were fully qualified?
