The new teacher training ad, with its somewhat child-unfriendly image of headless people wandering around, is unlikely to help recruitment. “Oi” – it is saying – “you, in the braindead masses. Why not do the only job in the world where you use your brain. Teaching.” An advert whose hypothesis is only proven by its own ad agency. I use my brain plenty at work, not fannying around with a Van Der Graaf generator making self deprecating jokes about my lack of hair. The ad succeeds in insulting its target audience and making teaching look like doing bad stand up comedy. (Which if Teachers is anything to go by…)
