I haven't written one for 12 years. I've been a full time mum for 8 years and I've found a job I want to apply for. Donkeys' years ago on PGCE we were told to begin a letter with our philosophy of education but that seems very cheesey. I've tried drafting one and have begun with 'I am a very experienced teacher' blah blah into what experience I've got but it doesn't read well.
Really need some help.
