How do I know this? Well, it's all do with an initiative from the government. The Excellent Teacher scheme aims to boost standards in England by getting experienced teachers to coach others. The Department for Education and Skills expected 5,000 teachers to apply - but only 34 have, and just 26 qualified.
So, if only 26 teachers are good enough to become excellent teachers, then the rest of must be pretty rubbish at our jobs.
