When I were a lad, several of the teachers at my Boy's Secondary Modern school were ex-servicemen - and proud of it! Not only were they bl00dy good teachers, but they also knew how to handle the troublemakers. Sadly, that generation have long gone, and look what they've been replaced by! It's no surprise that so many state schools are failing these days.
Maybe this government should consider giving currently serving military personnel, who have instructional skills, proper accreditation and maybe some financial incentives to entice them into the teaching profession?
